Beginning in 1993, Safe Drinking Water Act (SDWA) regulations required the 626 large community water systems in New Jersey to monitor their 2,600 wells and 45 surface-water intakes quarterly for 23 pesticides. Monitoring costs would increase consumers’ water bills by $6.4 million each year. The New Jersey Department of Environmental Protection (NJDEP) can waive monitoring requirements for wells or intakes that are not vulnerable to pesticide contamination.
The U.S. Geological Survey (USGS), in cooperation with NJDEP, determined the vulnerability of wells and surface-water intakes to pesticide contamination on the basis of hydrogeology and pesticide use. The NJDEP estimated that because many wells and intakes are not vulnerable to contamination by pesticides, monitoring waivers will save taxpayers at least $5.1 million annually for a one-time study cost of $1 million.
