(a) The director of health is authorized to provide, upon request, testing for all private water supplies used as sources of drinking water. This testing shall be on a voluntary basis and does not confer upon the director or department of health jurisdiction over that private water supply, in addition to that provided for elsewhere.

(b) The director is further authorized to provide, upon request, testing for public water supplies used as sources of drinking water. The testing shall be on a voluntary basis and does not confer upon the director or department of health jurisdiction over public water supplies in addition to that provided for elsewhere.

(c) The director of health is further authorized to provide, upon request, testing for other substances of public health concern such as radon in air, lead in paint and soil, and other indoor air pollutants.
