The New Jersey Residential Well-Testing Program--a case study: Randolph Township.

Since 1993, several wells have been found to be contaminated in Randolph Township, New Jersey. As a result, the local health department believed there was a need to develop an ordinance that would protect the health of private well users. Samplings of 1,488 private and nonpublic wells in Randolph Township were used to provide the basis for the ordinance proposal.
