Section 1.

Inorganic and Organic Chemical Sampling, Analytical Techniques, and Maximum Contaminant Levels.

(1)

A public water system shall meet the requirements for inorganic chemicals as established in 40 C.F.R. 141.11, 141.23, 141.41, 141.51, and 141.62.

(2)

A public water system shall meet the requirements for organic chemicals as established in 40 C.F.R. 141.24, 141.50, and 141.61.

Section 2.

Section 3.

Sampling, Analysis, Reporting, and Treatment for Secondary Contaminants.

(1)

A public water system that treats groundwater or surface water shall sample for secondary contaminants as established in 40 C.F.R. 143.1 through 143.4.

(a)

An analysis for secondary contaminants shall be performed if a new source of water supply is proposed to the cabinet for preliminary approval pursuant to 401 KAR 8:100, Section 1.

(b)

Excessive amounts of these contaminants or excessive costs for removal of these contaminants shall be grounds for rejection of the proposed source of water.

(2)

(a)

An existing public water system that treats groundwater or surface water shall sample for, analyze, and report the secondary contaminants listed in 40 C.F.R. 143.3 annually, and if consumer complaints indicate the presence of one (1) or more of these contaminants.

(b)

Treatment shall be adequate to assure that the secondary contaminant level does not exceed the maximum level limits established in 40 C.F.R. 143.3.

(3)

A sample shall be taken from each entry point to the distribution system.

(4)

If a secondary maximum contaminant level established in 40 C.F.R. 143.3 is exceeded by a supplier of water, the cabinet may direct that supplier to modify the treatment procedure or to locate a more suitable source of water if the exceeded contaminant level results in a violation of the primary drinking water standards or in consumer complaints.
