(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:
(1) For new construction serving a single
residence:
Calcium
Magnesium
Sodium
pH
Specific conductance
Hardness
Total alkalinity
Chloride
Sodium absorption ratio
(2) After 6 months of occupancy in the new
residence:
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.
