¶ 1 Plaintiffs/appellants challenge recent amendments to the Oklahoma Groundwater Law, 82 O.S.2001, §§ 1020.1, et seq. The challenged legislation,2 codified at 82 O.S.Supp.2003, §§ 1020.9, 1020.9A and 1020.9B, relates to “sensitive sole source groundwater basins.” It defines “sensitive sole source groundwater basin” as:
a major groundwater basin or subbasin all or a portion of which has been designated as a “Sole Source Aquifer” by the United States Environmental Protection Agency pursuant to the Safe Drinking Water Act, as of the effective date of this act, including any portion of any contiguous aquifer located within five (5) miles of the known areal extent of the surface out-crop of the sensitive sole source groundwater basin.
82 O.S.Supp.2003, § 1020.9A(B)(1). The challenged legislation imposes moratoria on 1) issuing temporary permits that would lead to any additional municipal or public use of water from a sensitive sole source groundwater basin at locations outside of the basin and 2) contracting by municipalities and other political subdivisions outside a sensitive sole source groundwater basin for water from the basin. 82 O.S.Supp.2003, §§ 1020.9A(B)(1) and 1020.9B(A). The moratoria are effective until a hydrological study is completed and the Oklahoma Water Resources Board determines a maximum annual yield for the sensitive sole source groundwater basin. 82 O.S.Supp.2003, §§ 1020.9A(B)(2) and 1020.9B(B). The challenged legislation also requires the Oklahoma Water Resources Board, before issuing a permit to withdraw water from a sensitive sole source groundwater basin, to determine if the proposed use is likely to degrade or interfere with springs or streams emanating in whole or in part from water originating from the sensitive sole source groundwater basin. 82 O.S.Supp. 2003, § 1020.9(A)(1)(d).
¶2 The legislation is challenged as: 1) a special law regulating municipal and county affairs contrary to the Okla. Const., art. 5, § 46; 2) a special law relating to a subject area that can be dealt with in a general law contrary to the Okla. Const., art. 5, § 59; 3) a special law with no notice as required by the Okla. Const., art. 5, § 32; 4) a taking of private property without just compensation contrary to the Okla. Const., art. 2, § 24 and the U.S. Const., Fifth Amendment, Takings Clause; and 5) discriminatory treatment of landowners contrary to the U.S. Const., Fourteenth Amendment, Equal Protection Clause. We conclude the challenged legislation is valid and uphold the legislation codified' at 82 O.S.Supp.20Q3, §§ 1020.9, 1020.9A and 1020.9B.
I. Facts and Proceedings Below
¶ 3 The plaintiffs/appellants, Jacobs Ranch, LLC, Roos Ranch, Inc., and Roos Resources, Inc., claim rights in and to the groundwater in the Arbuckle-Simpson Groundwater Basin underlying them property in Pontotoc County. They also claim to be holders of temporary permits for the withdrawal of that groundwater;
¶ 4 The defendants/appellees, Oklahoma Water Resources Board (OWRB) and Duane A. Smith, Executive Director of the OWRB, are responsible for the administration and enforcement of Oklahoma’s groundwater law. The municipal intervenors, Ardmore, Davis, Durant, Sulphur, Tishomingo, Wynnewood and Ada, receive all or a portion of their water supply from the Arbuckle-Simpson Groundwater Basin. Other intervenors are the Arbuckle Master Conservancy District and some of the members of Citizens for the Preservation of the Arbuckle-Simpson Aquifer.
¶ 5 The Arbuckle-Simpson Groundwater Basin is a major groundwater basin as defined by the Oklahoma Groundwater Law. 82 O.S.2001, § 1020.1. It lies entirely within the State of Oklahoma. It extends into five counties- Pontotoc, Murray, Johnston, Carter and Coal counties. It has depths- greater than any other aquifer in the state, and its hydraulic and geologic conditions are unique in the state. It is a predominately carbonate *847aquifer that provides high-sustained flows to its springs and streams. Its carbonate formation, the limestone and dolomite strata, causes the recharge and discharge rates to be less predictable than aquifers with the more common sandstone and shale formations.
¶ 6 The Arbuckle-Simpson Groundwater Basin serves as a source of good-quality drinking water to many domestic users, municipalities and parks in the area overlying the basin. The United States Environmental Protection Agency (EPA) has designated a portion of the Arbuckle-Simpson Groundwater Basin as a sole source aquifer pursuant to the Safe Drinking Water Act, 42 U.S.C. §§ 300g and 300h-3 e.3 There are a total of seventy-two designated sole source aquifers in the continental United States.
¶ 7 The municipal intervenors receive drinking water from the Arbuckle-Simpson Groundwater Basin or sources that originate in the basin. Municipal and public water supply use is one of the largest uses of water permitted to be withdrawn from the Arbuck-le-Simpson Groundwater Basin.
¶8 The OWRB has the duty to make a hydrologic survey and investigation of each groundwater basin in Oklahoma at least every twenty years. 82 O.S.2001, § 1020.4. The OWRB also has the duty to determine a maximum annual yield of groundwater to be produced from each groundwater basin. 82 O.S.2001, § 1020.5. Any regular permit to withdraw water from a groundwater basin must be based upon a completed hydrological study and a maximum annual yield determination. 82 O.S.2001, § 1020.11.
¶ 9 The Oklahoma Geological Survey and the United States Geological Survey studied the hydrology of the Arbuckle-Simpson Groundwater Basin. In 1990, those agencies reported on the hydrology of the Arbuckle-Simpson Groundwater Basin but the report was not prepared to support a finding of the maximum annual yield by the OWRB. The OWRB advises that a hydrological study sufficient to determine a maximum annual yield will be completed in the calendar year of 2008.
' ¶ 10 In 1985 and 1986, the OWRB issued temporary permits to withdraw water for public and municipal use to plaintiffs/appellants based on their interests in land in Pon-totoc County overlying the Arbuckle-Simpson Groundwater Basin. The temporary permits were revalidated annually until 2003. Beginning in 2003, numerous protests objecting to any further revalidation of plaintiffs’/appellants’ temporary permits have been filed with the OWRB.
¶ 11 Plaintiffs/appellants did not withdraw any water from the Arbuckle-Simpson Groundwater Basin pursuant to their temporary permits.4 However, in 2003 plaintiffs/appellants proposed to begin selling more than twenty billion gallons of water annually from the Arbuckle-Simpson Groundwater Basin to municipalities in Cana*848dian County, Oklahoma. Although no Canadian County municipality is involved in this litigation, plaintiffs/appellants assert that the Canadian County municipalities depend on groundwater sources that may become impractical in the future due to more restrictive arsenic standards for drinking water. Those municipalities also purchase water from Oklahoma City.5
¶ 12 Without a sufficient hydrological study, the effect of plaintiffs’/appellants’ proposed withdrawal of water from the Arbuck-le-Simpson Groundwater Basin can not be determined by the OWRB. However, it is undisputed that: 1) aquifers in Oklahoma have suffered irreversible decline where withdrawals exceeded the aquifer’s ability to recharge, such as the Ogallala Aquifer; 2) decline in the groundwater level has resulted in the loss of the natural flow of streams, such as the Beaver River in the Oklahoma panhandle; and 3) a decline in the groundwater level of the Arbuckle-Simpson Groundwater Basin could jeopardize the flow of springs and streams, such as the spring that is the source of the water for the city of Ada.
¶ 13 In 2003, the Oklahoma Legislature passed Senate Bill No. 288 and the Governor signed it into law.6 The measure expressly found that “a moratorium is necessary on the issuance of certain temporary permits on certain sensitive sole source groundwater basins or subbasins to protect the health, safety and welfare of the people of Oklahoma.” 82 O.S.Supp.2003, § 1020.9A(A).
¶ 14 A major groundwater basin designated as a sole source aquifer, the Arbuckle-Simpson Groundwater Basin falls within the statutory definition of a “sensitive sole source groundwater basin.” 82 O.S.Supp.2003, § 1020.9A(B)(1). Presently, it is the only sensitive sole source groundwater basin in the state.
¶ 15 Plaintiffs/appellants filed this action asking that the sensitive sole source groundwater basin law be struck down as inconsistent with the federal and state constitutions. They moved for summary judgment.
¶ 16 The district court concluded that the sensitive sole source groundwater basin law is valid and enforceable and entered summary judgment in favor of the defendants and intervenors. Plaintiffs appealed. This Court retained the appeal.
II. Standard of Review
¶ 17 Summary judgment disposes solely of issues of law which we review by a de novo standard. Manley v. Brown, 1999 OK 79, 989 P.2d 448, 455. Our de novo review is plenary, independent and non-deferential. Gladstone v. Bartlesville Indep. Sch. Dist. No. 30, 2003 OK 30, ¶ 5, 66 P.3d 442, 445.
¶ 18 Here, the issue is the constitutionality of the 2003 amendments to the groundwater statutes. There is a strong presumption that the statutes are constitutional. Black v. Ball Janitorial Service, Inc., 1986 OK 75, ¶ 5, 730 P.2d 510, 512. In deciding their constitutionality, the statutes will be upheld unless they are clearly inconsistent with the constitution. Id.
III. The trial court’s ruling on plaintiffs’ standing
¶ 19 The dissenting opinion raises a threshold issue which we are obliged to address before we proceed to review the merits of the summary judgment on appeal. The dissent takes the position that there is no clear paper trail of the trial court’s ruling on plaintiffs’ standing raised in defendants’ dismissal motion and asserted as an affirmative defense in intervenors’ answer.
¶ 20 The record before this Court shows that the trial court did make a determination that plaintiffs have standing to maintain this declaratory judgment action. On July 15, 2003, the defendants filed a motion to dismiss for, among other grounds, lack of standing. The motion was fully briefed. On September 25, 2003, the trial court heard arguments on *849the dismissal motion and entered a minute order overruling the motion. The trial court memorialized the September 25th ruling in a journal entry filed on October 6, 2003.
¶21 The appellate record does not show that the intervenors directly challenged plaintiffs’ standing in their summary judgment filings. The dissenting opinion correctly notes that the answers filed by the municipal intervenors alleged that plaintiffs lacked standing as an affirmative defense. But the dissenting opinion reaches to find a standing challenge in the attack on plaintiffs’ status as permit holders in the municipal intervenors’ cross-motion for partial summary judgment. It also reaches to find a standing challenge in the attack on plaintiffs’ lack of economic injury in the municipal intervenors’ argument responding to plaintiffs’ summary judgment argument that plaintiffs have not suffered an unconstitutional taking.
¶22 The appellate record shows that defendants directly challenged plaintiffs’ standing before the trial court.' The trial court ruled against the defendants on their challenge to plaintiffs’ standing in a journal entry filed of record. Intervenors did not file a motion to dismiss plaintiffs’ petition for lack of standing nor did they directly challenge plaintiffs’ standing to maintain this declaratory judgment action in their summary judgment filings. The plaintiffs filed their motion for summary judgment. The municipal in-tervenors filed a response to the summary judgment motion and a cross-motion for partial summary judgment. The citizen interve-nors filed a response to the summary judgment motion. The trial court proceeded to summarily dispose of the merits of the controversy argued by all the parties on summary judgment.
¶23 The trial court’s ruling on plaintiffs’ standing is not drawn by implication from mere silence. It is clear in this record that the trial court recognized plaintiffs’ standing, as it had earlier determined, when it allowed the plaintiffs to be heard on the merits and when it proceeded to consider and rule upon the merits of the summary judgment filings.
IV. Exercise of police power to regulate water resources
¶ 24 Defending the constitutionality of the challenged legislation, the Attorney General argues that the measure is an exercise of the Legislature’s police power for the purpose of regulating the state’s water resources. Police power is an attribute of state sovereignty. Gibbons v. Missouri K. & T.R. Co., 1930 OK 108, 285 P. 1040, Syllabus by the Court. It is generally an inherent power of the state legislature that extends to the whole system of internal regulation by which the state preserves public order, prevents offenses .against the state, and insures to the people the enjoyment of rights and property reasonably consistent with like enjoyment of rights and property by others. Id. Through the exercise of its police power, the Legislature determines what is necessary for the peace and welfare of the people. Edmondson v. Pearce, 2004 OK 23, ¶ 34, 91 605, 623, 91 P.3d 605.
¶ 25 The Legislature may exercise its police power to regulate any property within the jurisdiction of the state when regulation is necessary to secure the general safety, the public welfare, and the peace and good, order of the community. Gibbons, 285 P. at 1042. The Legislature may exercise its police power to regulate the use and enjoyment of property when the free exercise of such use is detrimental to the public interest. Phillips Petro. Co. v. Corp. Comm’n, 1956 OK 313, 312 P.2d 916.
¶26 It is a basic principle that water is a natural resource, Sheldon v. Grand River Dam Auth., 1938 OK 76, 76 P.2d 355; Anderson-Prichard Oil Corp. v. Okla. Corp. Comm’n, 1951 OK 234, 241 P.2d 363; Kline v. Okla. Water Resources Bd., 1988 OK 18, 759 P.2d 210, which the state may regulate for the health, welfare and safety of the people. See, Wyoming v. Colorado, 259 U.S. 419, 42 S.Ct. 552, 66 L.Ed. 999 (1922); Fort Gratiot Sanitary Landfill, Inc. v. Mich. Dept. Of Natural Resources, 504 U.S. 353, 365, note 6, 112 S.Ct. 2019, 2026-2027, 119 L.Ed.2d 139 (1992). The Legislature may exercise its police power to protect the state’s water irrespective of the rights of private owners of the land most immediately *850concerned. Hudson County Water Co. v. McCarter, 209 U.S. 349, 355, 28 S.Ct. 529, 531, 52 L.Ed. 828 (1908). For the health, welfare and safety of its citizens, the Legislature may regulate a landowner’s use and enjoyment of water resources to prevent waste and infringement on the rights of others. Franco-American Charolaise, Ltd. v. Okla. Water Resources Bd., 1990 OK 44, 855 P.2d 568, 576; Kline v. Okla. Water Resources Bd., 759 P.2d at 212.
Y. Oklahoma’s Groundwater Statutes
¶ 27 The OWRB asserts that the Legislature, in regulating groundwater, has classified groundwater basins as minor basins and major basins and that the challenged legislation is a further classification for the protection of basins that supply drinking water for communities. The OWRB argues that the challenged legislation is sound management and stewardship of unique aquifers within the current regulatory system of allocation for reasonable use.
¶ 28 An overview of the groundwater statutes is helpful in our analysis of the challenged legislation. In 1949, the Oklahoma Legislature enacted the Oklahoma Ground Water Law to regulate the taking and use of ground water in order “to conserve and protect the ground water resources of the State.”7 The 1949 law restricted landowners to withdrawing only the safe annual yiéld of a basin as measured by its average annual recharge. 82 O.S.1951, § 1015; Okla. Water Resources Bd. v. Texas County Irrigation and Water Resources, 1984 OK 96, ¶ 6, 711 P.2d 38, 41. The Legislature determined that the ground water regulation served “the interest of agricultural stability, domestic, municipal, industrial and other beneficial uses, general economy, health and welfare of the State and its citizens_” 82 O.S.1951, § 1003.
¶29 In 1972, the Oklahoma Legislature repealed the 1949 Ground Water Law8 and enacted a new statutory scheme “to utilize the groundwater resources of the state.” The 1949 conservation policy was replaced'by a reasonable utilization policy. Okla. Water Resources Bd. v. Texas County Irrigation and Water Resources, 711 P.2d at 41. The 1972 legislation provided for “the allocation for reasonable use based on hydrologic surveys of fresh ground water basins or subba-sins to determine a restriction on the production, based upon the acres overlying the ground water basin or subbasin.” 82 O.S.Supp.1972, § 1020.2. In the 1972 enactment, the Oklahoma Legislature declared that a water utilization policy was necessary for the health and welfare of the state and its citizens. Id.
¶ 30 Enacted in the exercise of the Legislature’s police power, the current groundwater law, 82 O.S.2001, §§ 1020.1 et seq., is the 1972 regulatory regime for the reasonable utilization of the state’s groundwater resources and the subsequent amendments thereto.- The challenged amendments impose a moratorium against the transfer of water for out-of-basin municipal and public use and interject a conservation requirement to the utilization regime. As amended, the groundwater law requires a permit applicant to show that the withdrawal of water is not likely to degrade or interfere with springs or streams emanating in whole or in part from water originating from the sensitive sole source groundwater basin.
VI. The Okla. Const., art. 5, § 59
¶ 31 Plaintiffs/appellants contend that the challenged legislation is unjustifiably limited to the Arbuckle-Simpson Groundwater Basin without naming it and that the limitation is irrational and a subterfuge for a special law, relying on Elias v. City of Tulsa, 1965 OK 164, 408 P.2d 517. They argue that the classification of “sensitive sole source groundwater basin” is invalid because it is not reasonably related to a valid legislative objective, citing Reynolds v. Porter, 1988 OK 88, 760 P.2d 816. They further argue that the withdrawal of water for out-of-basin use and the reduction in stream flow due to groundwater pumping could be addressed on a statewide basis as was done in the groundwater statutes, 82 O.S.2001, §§ 1020.1-*8511020.22, and that the subject could be legislated upon in a general law as required under art. 5, § 59, citing Grant v. Goodyear Tire & Rubber Co., 2000 OK 41, 5 P.3d 594.
¶ 32 The Oklahoma Constitution, art. 5, § 59 imposes two distinct restrictions upon lawmakers. It requires that “laws of a general nature” must operate uniformly throughout the state. It also prohibits the enactment of a “special law” where a “general law” can be applied. Article 5, § 59 reads:
Laws of a general nature shall have a uniform operation throughout the State, and where a general law can be made applicable, no special law shall be enacted.
¶ 33 Article 5, § 59 was included in the original Constitution of the State of Oklahoma. At statehood the meanings of the terms “law of a general nature,” “general law,” “special law” and “uniform operation” were established.9 A “law of a general nature” related to a subject of common interest to the whole state. J.G. Sutherland, Statutes and Statutory Construction 148-150 (1891). A “general law” related to a subject of common interest to the whole state and embraced the whole subject or a whole class related to the subject.10 Id. Although it might have related to a subject of common interest to the whole state, a “special law” embraced particular persons or things of a class but not the whole subject or whole class. Id. A law had “uniform operation” throughout a state when it related to a subject of common interest to the whole state and the Legislature did not apply it to particular localities or prohibit its operation in particular locations, even though it did not practically operate in every part of the state. Id.
¶ 34 Immediately after statehood, this Court considered the uniformity restriction imposed upon lawmakers by art. 5, § 59. Anderson v. Ritterbusch, 1908 OK 250, 98 P. 1002, State ex rel. Smith v. Brown, 1909 OK 199, 103 P. 762, and Burks v. Walker, 1909 OK 317, 109 P. 544. In Anderson, a statute establishing a procedure to collect taxes on omitted property was challenged as contrary to art. 5, § 59 because it had no practical application in the eastern half of the state, pre-statehood Indian Territory. Anderson determined the challenged statute had uniform application across the state even though the dissimilarities in the governmental and industrial conditions in Oklahoma Territory and Indian Territory caused a difference in the statute’s application. In so ruling, Anderson quoted Noffzigger v. McAllister, 12 Kan. 315:
Whenever a law of a general nature is passed by the Legislature for the whole state, and is not applied by the Legislature to any particular locality thereof and has no words prohibiting its operation in any particular locality thereof, it is a law of uniform operation throughout the state, within the meaning of the constitutional provision, although it may not practically have operation in every part of the state.
Anderson, 1908 OK 250, ¶ 26, 98 P. at 1009.
¶ 35 In State ex rel. Smith v. Brown, a statute providing for the removal of sheriffs, *852constables, marshals, police officers, and city and county attorneys for failure to diligently enforce the prohibition laws was challenged as contrary to art. 5, § 59 because it applied to some but not all county, township and municipal officers. State ex rel. Smith determined the challenged statute had uniform application across the state because it applied to all the local officers in the class of officers who had the duty to enforce the prohibition laws.
¶ 36 In Burks v. Walker, a statute establishing a county superior court in each county that had at least 30,000 inhabitants and a city with 8,000 inhabitants was challenged as a special law with local application. Recognizing that a law of a general nature may have uniform operation throughout the state even though it operates only upon a legislative class, Burks, 1909 OK 317, ¶ 23, 109 P. at 549, explained:
In order for a law to be general in its nature and to have a uniform operation, it is not necessary that it shall operate upon every person and every locality in the state. A law may be general and have a local application or apply to a designated class if it operates equally upon all the subjects within the class for which it was adopted. To determine whether or not a statute is general or special, courts will look to the statute to ascertain whether it will operate uniformly upon all the persons and parts of the state that are brought within the relation and circumstances provided by it. People ex rel. v. Hoffman, 116 Ill. 587[, 5 N.E. 596, 8 N.E. 788 (1886)]; Nichols v. Walter et al., 37 Minn. 264, 33 N.W. 800. And the operation is uniform if it affects alike all persons in like situation. But where a statute operates upon a class, the classification must not be capricious or arbitrary and must be reasonable and pertain to some peculiarity in the subject matter calling for the legislation. As between the persons and places included within the operation of the law and those omitted, there must be some distinctive characteristic upon which a different treatment may be reasonably founded and that furnish a practical and real basis for discrimination. Nichols v. Walter, supra.
¶ 37 This Court has tested a plethora of statutes for conformity with the requirements of art. 5, § 59. Adhering to the art. 5, § 59 principles pronounced at statehood, our extant jurisprudence tests a legislative classification in a law of a general nature to determine if the distinction of the persons, entities or things (the class) has a reasonable and substantial basis and a sound and rational relation to the subject of the legislation. See, Hudgins v. Foster, 1928 OK 243, ¶ 30, 267 P. 645, 649 (striking down a statute abolishing township offices in forty-nine counties but not the remaining twenty-eight counties for lack of reasonable basis); Roberts v. Ledgerwood, 1928 OK 723, ¶ 18, 272 P. 448, 452 (striking down a statute imposing the duty to oversee road and bridge work on county commissioners, with incremental salaries, only in counties that fall within specific population levels as arbitrary and without relation to the subject matter of the statute); Sheldon v. Grand River Dam Authority, 1938 OK 76, ¶ 17, 76 P.2d 355, 361 (upholding a statute creating a reclamation district for the Grand River Dam Authority as reasonable with sound and rational relation to the subject of the legislation); Elias v. City of Tulsa, 1965 OK 164, ¶¶ 9-10 and 20, 408 P.2d 517, 519-520 (striking down a statute providing for a city-county coopera-tivé planning commission in cities within specific population limits fitted to Tulsa only as arbitrary and a subterfuge); Isaacs v. Oklahoma City, 1966 OK 267, 437 P.2d 229 (upholding population-based classification for urban redevelopment as reasonable); Tulsa Expo. & Fair Corp. v. Bd. Of County Comm’rs, 1970 OK 67, ¶ 22, 468 P.2d 501, 507 (striking down a statute authorizing county fairs only in counties having a population between 100,000 and 200,000 as not related to the subject matter); Reynolds v. Porter, 1988 OK 88, 760 P.2d 816 (striking down medical negligence statute of limitations as special law prohibited by art. 5, § 46); and Kerley v. Uniroyal Goodrich Tire Co., 2000 OK 62, 10 P.3d 230 (striking down workers’ compensation statute allowing only self-insured employers to recoup overpayment of temporary disability as underinclusive class legislation). Under the reasonable basis and the rational relation tests, the court must *853determine if the legislative classification rests upon a reasonable difference that bears a rational relation to the purposes and goals of the legislation, i.e., does the classification further a legitimate state purpose or interest'.
VII. Analysis of the challenged legislation under the Okla. Const., art. 5, § 59
¶ 38 The essence of plaintiffs’/appellants’ challenge is that the sensitive sole source groundwater legislation creates an invalid classification prohibited by the Okla. Const., art. 5, § 59. This challenge requires us to inquire into 1) the nature of the legislation, 2) the legislative classification and 3) the uniformity of its operation.
¶39 As to its nature, the sensitive sole source groundwater basin legislation relates to the state’s water resources that supply safe drinking water to the basin area and to all the people who live, work or visit there. Unquestionably, safe drinking water is a subject of common interest throughout the state and a rightful subject for legislative regulation. The sensitive sole source groundwater basin legislation is a law of a general nature.
¶ 40 As to the legislative classification of “sensitive sole source groundwater basin,” we must determine whether there are distinguishing characteristics which make “sensitive sole source groundwater basins” really different from other groundwater basins in the state. The Legislature determined that a sensitive sole source groundwater basin is different from other major groundwater basins by virtue of the EPA’s “Sole Source Aquifer” designation. The EPA designation protects all within a sole source aquifer area that depend upon the aquifer for safe drinking water. The designation allows the EPA to review federal financially assisted projects in the out-crop area of a sole source aquifer or its streamflow source area to ensure projects do not contaminate the aquifer and threaten public health. 54 F.R., 39230. We conclude the EPA’s designation of “Sole Source Aquifer” is a substantial and reasonable distinction that makes the “sensitive sole source groundwater basin” class different from other major groundwater basins in this state.
¶ 41 We must next determine whether the classification is rationally related to the purpose of the legislation. Plaintiffs/appellants assert that the actual purpose of the challenged legislation is to stop the transport of water to Canadian County municipalities for municipal and public use without interfering with other temporary permits. The legislation does not single out Canadian County municipalities. It finds that a moratorium on the issuance of temporary permits on “sensitive sole source groundwater basins” is needed to protect the health, safety and welfare of the people of Oklahoma. 82 O.S.Supp. 2003, § 1020.9A(A). And, it imposes a moratorium on the issuance of temporary permits for out-of-basin municipal or public use until it is determined that further removal -of water from the “sensitive sole source groundwater basin” will not reduce the flow of its springs and streams. 82 O.S.Supp.2003, § 1020.9A(B)(2).
¶42 It is undisputed that the source of safe drinking water for in-basin use may be degraded by the transfer of large quantities of water for out-of-basin use. It is also undisputed that public use is one of the largest uses of the Arbuckle-Simpson groundwater. Anticipating that the transfer of water to out-of-basin municipalities might interfere with the availability of safe drinking water for in-basin use, the Legislature decided to preserve the sources of safe drinking water for in-basin use until completion of a hydrological study and determination of a maximum annual yield. Accordingly, we conclude that the purpose of the challenged legislation is to conserve the sole source of safe drinking water for use in the area overlying the sensitive sole source groundwater until a hydrological study is completed and a maximum annual yield is determined that ensures the withdrawal of water will not interfere with the in-basin drinking water supply.
¶ 43 Different treatment of in-basin public use and out-of-basin public use does not make the legislation a special law because the in-basin area and out-of-basin areas are not in like situations. The in-basin area relies solely on the aquifer for drinking water. The bases for the EPA designation are that the drinking water in the designated sole *854source aquifer area is provided by the Ar-buckle-Simpson aquifer and that there are no existing alternative drinking water sources nor cost-effective sources capable of supplying the drinking water demands for the designated area. 54 F.R. 39230. The distinction between in-basin use and out-of-basin use has a rational relation to the purpose of the legislation. We conclude that the classification of groundwater basins designated by the EPA as “Sole Source Aquifers” is rationally related to the conservation of safe drinking water for use in the overlying area.
¶ 44 As to its uniform operation, we must determine whether the “sensitive sole source groundwater basin” classification limits the legislation’s application to particular locations or particular persons thereby preventing statewide uniform application of the law. Plaintiffs/appellants argue that the class embraces only the Arbuckle-Simpson Groundwater Basin and those persons having an interest in the overlying land. They urge that the class is not open to any other groundwater basins in the state that the EPA may in the future designate as sole source aquifers because the legislation defines sole source aquifer designated by the EPA “as of the effective date of this act.” We disagree.
¶45 The challenged legislation is framed in general language to apply to the whole class of major groundwater basins designated by the Administrator of the EPA to be sole source aquifers in accordance with the Safe Drinking Water Act, 42 U.S.C. §§ 300g and 300h-3(e). As a general rule, a statute is applied prospectively unless the language evidences an intent that it also be applied retrospectively.11 The statutory language defining the “sensitive sole source groundwater basin” class as those basins designated sole source aquifers “as of the effective date of this act” expresses an intent that the legislation shall apply to any sole source aquifer so designated prior to its effective date. However, we glean no intent, express or implicit, from the legislation that it would not apply to any major groundwater basin in this state which, in the future, the EPA designates as a sole source aquifer. We conclude the sensitive sole source groundwater basin legislation operates uniformly throughout the state upon all major groundwater basins designated as sole source aquifers before and after its effective date and all persons brought within the circumstances provided by it. The fact that there was only one groundwater basin designated by the EPA as a “Sole Source Aquifer” when the challenged legislation was enacted does not destroy its uniform operation throughout the state.
¶ 46 In summary, the challenged sensitive sole source groundwater basin legislation is a law of a general nature. The legislative classification of “sensitive sole source groundwater basins” is reasonable and rationally related to the purpose of the legislation. The sensitive sole source groundwater basin legislation operates uniformly throughout the state upon all major groundwater basins designated, presently and in the future, as sole source aquifers. The challenged legislation is a valid general law under the Okla. Const., art. 5, § 59. Because the challenged legislation is a general law, we need not consider plaintiffs’/appellants’ argument on the notice requirements for a special law under the Okla. Const., art. 5, § 32.
VIII. The Okla. Const., art. 5, § 46
¶ 47 Plaintiffs/appellants challenge the sensitive sole source, groundwater basin legislation as contrary to art. 5, § 46 of the Oklahoma Constitution.12 They contend that the moratorium on contracts in the sensitive sole source groundwater basin legislation is a special law regulating municipal and county affairs.13 They argue that the moratorium *855regulates municipal and county affairs because it impacts the ability of out-of-basin municipalities and counties to enter into contracts for their public water supplies. They also argue it is a special law because it applies to some but not all counties and municipalities in the state and to only the Arbuckle-Simpson Groundwater Basin.
¶ 48 We have already determined that the challenged legislation relates to a subject of common interest throughout the state and that it regulates the state’s water resources through the exercise of the state’s police power for the health, welfare and safety of the public. Clearly, regulation of groundwater resources for the benefit of the public is a statewide concern. Although we are mindful of the fact that water supply is a basic concern of each of our political subdivisions, we do not view the regulation of the state’s water resources as an affair of counties, cities or towns under art. 5, § 46. Accordingly, we need not ’ further consider plaintiffs’/appellants’ art. 5, § 46 arguments.
¶49 We have also determined that the purpose of the challenged legislation is to conserve the sole source of safe drinking water for in-basin use until a hydrological study is completed and a maximum annual yield is determined that ensures the withdrawal of water will not interfere with the in-basin drinking water supply. Obviously, § 1020.9B was intended to serve that legislative purpose.
IX. The Takings Clauses in the U.S. Const., Fifth Amendment and the Okla. Const., art. 2, § 24.
¶ 50 Plaintiffs/appellants argue that the sensitive sole source groundwater basin legislation constitutes a taking of private property without just compensation contrary to the U.S. Const., Fifth Amendment, Takings Clause and the Okla. Const., art. 2, § 24. We are not convinced. The general rule is that the Legislature may restrict the use and enjoyment of the state’s water resources by exercise of its police power for the preservation of the public health, safety and welfare without compensating the property owner. Franco-American Charolaise, Ltd. v. Okla. Water Resources Bd., 1990 OK 44, 855 P.2d 568, 576. The challenged legislation regulates the state’s water resources expressly “to protect the health, safety and welfare of the people of Oklahoma.” 82 O.S.Supp.2003, 1020.9A(A).
¶ 51 The Takings Clause of the Fifth Amendment to the Constitution of the United States provides “nor shall private property be taken for public use without just compensation.” The recent case of Tahoe-Sierra Preservation Council, Inc. v. Tahoe Regional Planning Agency, 535 U.S. 302, 122 S.Ct. 1465, 152 L.Ed.2d 517 (2002), observed that the Fifth Amendment Takings Clause requires compensation whenever the government appropriates private property for a public interest, but it does not necessarily require just compensation where government regulations “prohibit a property owner from making certain uses of her private property.” Id. at 321-322, 122 S.Ct. 1465. Whether a regulatory prohibition amounts to a taking under the Fifth Amendment depends upon all the relevant facts and circumstances. Id. at 322, 122 S.Ct. 1465.
¶ 52 The Oklahoma Constitution, art. 2, § 24 provides that “[p]rivate property shall not be taken or damaged for public use without just compensation.” While a governmental taking of private property for public use must be compensated, a reasonable government regulation of the property is not compensable. Suntide Inn Operating Corp. v. State, 1977 OK 204, 571 P.2d 1207, 1209. In this regard, Suntide, at 1210, quoted Gib *856 bons v. Missouri, K & T.R. Co., 1930 OK 108, 285 P. 1040:
[A]cts done in the proper exercise of the police power, which merely impair the use of property, do not constitute a taking within the meaning of the constitutional requirements as to the making of compensation for the taking of property for public use, and accordingly do not entitle the owner of such property to compensation from the state or its agents, or give him any right of action for the injuries sustained. In other words, regulations which the state, in the exercise of its police power, authorizes with respect to the use of property are entirely independent of any question of compensation for such use. The question of compensation has no influence in establishing them. The exercise of the police power, therefore differs from the exercise of the right of eminent domain, which involves the appropriation of private property to public use, and requires, in its lawful exercise, pecuniary compensation for the loss inflicted on the owner.
It is well settled that the state, or its agents, in the exercise of its police power can extend this power only to such measures as are reasonable under all the circumstances. The means adopted must bear some real and substantial relation or be reasonably necessary for the accomplishment of a legitimate object falling within the scope of the police power, and the law or regulation must tend toward the preservation of public welfare, health, safety, or morals.
See also, Phillips Petro. Co. v. Corporation Comm’n, 1956 OK 313, 312 P.2d 916 (holding that a statute requiring a natural gas producer to make gas available to pump water for agriculture irrigation at a price fixed by the Corporation Commission is not a regulation under the police power but a taking of the producer’s property without due process of law and an appropriation of the producer’s property without just compensation); and Mattoon v. City of Norman, 1980 OK 137, 617 P.2d 1347 (concluding that the exercise of the police power to divert surface water onto one’s land must be tested under the rule of reason and holding that the enactment of a flood plain ordinance is not a per se taking of private property for public use).
¶ 53 The challenged legislation prohibits the OWRB from issuing temporary permits for out-of-basin municipal or public use until a hydrological study is completed and a maximum annual yield is determined. It also requires the OWRB, in considering applications for regular permits, to determine whether a proposed use is likely to degrade or interfere with springs or streams emanating from water originating from a sensitive sole source groundwater basin. We view this moratorium on temporary permits as a temporary restriction, at most, on the plaintiffs’/appellants’ use of their water. We view the additional requirement on applicants for regular permits to be a proper regulation of the state’s water resources in the exercise of the Legislature’s police power. We conclude that under the facts and circumstances presented on summary judgment, the temporary moratorium on plaintiffs’/appellants’ proposed use of water from the sensitive sole source aquifer and the additional permit requirement do not constitute a taking of private property'for public use under the constitutions of the United States and the State of Oklahoma.
X. The Equal Protection Clause in the U.S. Const., Fourteenth Amendment
¶ 54 Plaintiffs/appellants complain that the sensitive sole source groundwater basin classification causes disparate treatment of landowners and permit applicants and holders contrary to the U.S. Const., Fourteenth Amendment, Equal Protection Clause and Due Process Clause. We do not agree.
¶ 55 The United States Supreme Court has fashioned a two-tier equal protection framework. Equal protection analysis requires strict judicial scrutiny of statutes that operate to the peculiar disadvantage of a suspect class such as a class based on alien-age or ancestry or that interfere with the exercise of a fundamental right grounded in the constitution such as the right to vote, right to interstate travel and rights guaranteed by the First Amendment. Mass. Bd. Of Retirement v. Murgia, 427 U.S. 307, 312, 96 *857S.Ct. 2562, 2566, 49 L.Ed.2d 520 (1976). Equal protection analysis of other statutes is the less stringent rational basis standard. The legislative class is examined for a rational relation to the objective of the statute. Id. at 314, 96 S.Ct. 2562. The rational relation inquiry is a “relatively relaxed standard reflecting the Court’s awareness that the drawing of lines that create distinctions is peculiarly a legislative task” and such action by the Legislature is presumed valid. Id.
¶ 56 The “sensitive sole source groundwater basin” legislation does not relate to a fundamental right grounded in the constitution nor .does it operate upon a suspect classification. Equal protection analysis of the legislation does not require strict judicial scrutiny. We have already examined the legislation for purposes of art. 5, § 59 and concluded that the “sensitive sole source groundwater basin” classification has a reasonable basis and it is rationally related to the purpose of the law. We reach the same conclusions for purposes of equal protection. The challenged legislation does not deny plaintiffs/appellants equal protection of the laws.
XI. Conclusion
¶ 57 The utilization and the conservation of the state’s water resources are rightful subjects for legislative regulation. The Oklahoma Legislature not only has the power to regulate but also the profound responsibility to allocate this precious natural resource for the benefit of the whole state. The state’s water resources is a subject over which the Oklahoma Legislature must be vigilant and act with prudence for the benefit of all the citizens in the state. Unquestionably, a statewide comprehensive policy for both the utilization and the conservation of the state’s water is crucial to the health and welfare of every inhabitant in this state. We conclude the challenged groundwater legislation concerns a statewide interest and it operates uniformly throughout the state upon the legislative class of “sensitive sole source groundwater basins” that is reasonable and rationally related to the regulation of the state’s water resources. We hold the challenged legislation is a valid general law under the Okla. Const., art. 5, § 59.
¶ 58 The district court concluded that the challenged legislation is “addressed to the Arbuckle-Simpson Aquifer.”14 This conclusion is inconsistent with our conclusions that the legislation is drafted in general terms and that it applies to any major groundwater basin that, in the future, may be designated by the EPA as a sole source aquifer. Even so, the district court reached the correct result. Where the trial court reaches the correct result for the wrong reasons or on incorrect theories, it will not be reversed. Estate of Bartlett, 1984 OK 9, 680 P.2d 369; Dixon v. Bhuiyan, 2000 OK 56, 10 P.3d 888. Accordingly, we affirm the district court’s summary judgment in favor of defendants/appellees and intervenors/appellees.
