SECTION 252:631-3-23. Source water development

(a)   Continued protection for all sources. A PWS system shall provide protection for all sources of water from potential sources of contamination through ownership, zoning, easements, leasing or other legal means.

(b)   Reservoir and lake protection. PWS systems shall provide protection for a reservoir or lake used as a source of water. Control the marginal shoreline land by purchase or ordinance. If control is through the use of an ordinance, the ordinance must describe the water district boundaries and enforcement rules which shall include:

(1)   regulating the public health aspects of the water supply, waste and sewage disposal and recreation activities;

(2)   regulating the building of structures within the control area;

(3)   regulating aquatic activities involving human body contact with the water, including restricting body contact with the water during recreational or other activities when the water quality or public health may be adversely affected; and

(4)   regulating the removal of brush and trees to the high water elevation, regulating the protection from floods during construction within the control district, and regulating the plugging of wells which are inundated, in accordance with OWRB requirements.

(c)   Groundwater source protection. To protect all groundwater wells from microbiological contamination:

(1)   disinfect every new, modified or reconditioned groundwater well in accordance with AWWA standard specifications after completion of work on the well and the placement of the permanent pumping equipment;

(2)   upon completion of the well, the PWS system shall submit a copy of the well driller's log to the DEQ;

(3)   upon completion of the well, collect at least 2 bacteriologically safe samples on consecutive days. Collect samples after chlorine used to disinfect the well has been completely dissipated and submit the sampling records to the DEQ;

(4)   if any samples show the presence of coliform bacteria, additional samples shall be taken to determine the degree of contamination and the treatment required; and

(5)   if any of the samples show the presence of fecal coliform, a study shall be conducted and a determination made whether the groundwater source is under the direct influence of surface water.
