Peer Reviewed Private Well Research

The NJ Department of Environmental Protection, along with partnerships with the NJ Department of Health and Columbia University, have conducted many research projects in New Jersey throughout the years on private wells with a focus on outreach, treatment, arsenic, coliform bacteria, and gross alpha. Bolded names indicate members of the NJDEP and NJDOH.

NJ PWTA Data Summaries

Prior to the creation of our online interactive maps the Division of Science and Research compiled the summary data in reports.

The online interactive maps display the summary data of the NJ PWTA by county, municipality, census block group, and 2 mile by 2 mile grid.
