Louisiana Revised Statutes Tit. 30, § 2187. Monitoring of drinking water wells which provide public water supplies located near commercial hazardous waste facilities

(1) The secretary shall establish a test area around each such disposal facility. Such test area shall consist of a circle with a two-mile radius with the disposal facility at its center.

(2) The secretary shall divide each such test area into four quadrants of equal size by bisecting the test area twice with lines which are at right angles to each other.

(3) The secretary shall select, at random, one drinking well which provides public water supplies in each quadrant and shall sample and test the water from such well. Such selection, sampling, and testing shall be conducted every six months. The secretary shall not select any one such well in a quadrant for retesting until all such wells in that quadrant have been tested, unless there exists some need or reason to retest such well.

(4) The purpose of such sampling and testing shall be to insure that the drinking water wells which provide public water supplies located near said disposal facilities are not contaminated with toxic or hazardous pollutants which may be stored, treated, or disposed of at said disposal facility.
