048-2 Wyo. Code R. § 2-1
(a) For purposes of meeting the requirements of W.S. 35-1-229(b), the following tests shall be conducted. The listed analytic levels are the standards for the water source to be suitable for human consumption:
| Test | Standard |
| Total coliform | negative/100 milliliters |
| Total dissolved solids: | =1500 mg/L |
| Sulfates: | =750 mg/L |
| Nitrate + Nitrite as N: | =10 mg/L |
(b) Tests should be conducted within 90 days prior to conveyance of the property. Tap water samples should be collected by a public authority (sanitarian or other county or state health department official). In case arrangements cannot be made with a public official, then the conveyee may collect, or arrange for collection of the sample by a documented third party. When the sample is not collected by a public authority, appropriate containers and instructions for collection should be obtained from the laboratory performing the test. Under no circumstances may the conveyor or their representatives collect the water sample.
(c) Tests must be conducted by a laboratory certified by EPA for the analytes included in these rules and the cost of such tests is to be borne by the parties as stated in the legislation. The four tests listed above are the minimum requirement for transfer of property covered by the legislation. Copies of the analysis report shall be mailed to the conveyee and his/her agent, the conveyor and his/her agent, the lender, if there is one involved in the conveyance, and the State Health Department Epidemiologist. Lists of EPA approved laboratories may be obtained from the Department of Environmental Quality, Agriculture Department Extension Offices, the State Public Health Laboratory, and County Public Health Offices. Imposition of the requirement for EPA certification will become effective 1 July 1997.
(d) In addition, consideration must be given for the following as either party in the transaction may deem appropriate: Calcium Magnesium Sodium pH Specific conductance Hardness Total alkalinity Chloride Sodium absorption ratio Iron Zinc Lead* Fluoride Manganese Copper Corrosivity *First and second draw samples used to evaluate contributions from the plumbing, pump, and/or source water. Acceptable limits for these analytes may be found in Appendix A of this document.
(e) For private water supplies serving 2-9 residences, the entire list of major cations, anions and metals (underlined above) shall be tested from the source water. The total coliform shall be tested from the property being conveyed. Every connected property must receive a copy of the analysis from the testing laboratory. These standards will apply to new wells or other private water source(s). The complete list of tests would only be required once for a given water source, but the short list (four tests) is required each time a connected property changes ownership. The short list of tests does not need to be given to the other owners of property on the same system.
