NJDEP Private Well Testing Act summaries: private wells tested and reported to the state, 2002 to 2024. Shares are against the level the state applies to each contaminant, named in the last column; several are stricter than EPA.

What individual samples found

Each row summarizes every public sample for that contaminant inside Middle township. Above limit means above the EPA maximum contaminant level; where EPA has no enforceable limit, the row shows a health guideline or nuisance level instead.

Contaminant	Above limit	Samples	Detected	Median	Highest	Limit
Nitrate 1973 to 2026	4%	45	49%	0	23	10 mg/L EPA limit
Arsenic 1984 to 2026	0%	40	35%	0	0.47	10 ug/L EPA limit

Sampled fewer than 10 times, too few to summarize: Uranium (9), Fluoride (1), Copper (1), Radon (3), Chloride (1).

Over time

Share of samples above the limit by period. A cell needs ten samples to show; a comparison needs twenty in each period. Later periods sample fewer wells, and often the ones already known to have a problem.

What this means

Among homeowners in Middle township who sent a sample to the state lab, the health-based limits most often exceeded were PFOA (11% of 274 wells), total coliform (9% of 2,232 wells), and PFOS (6% of 274 wells). These are ordinary wells tested by their owners, so the shares are the best available picture of a typical well here, with one caveat: people test more often when they suspect a problem.

Manganese and iron exceed the state's advisory level in a sizable share of wells; these are mostly a taste, staining or diet issue rather than a toxicity one.

The rock under Middle township

Northern Atlantic Coastal Plain aquifer system

Semiconsolidated sand. Coastal plain sands like these give steady yields at moderate depth. Salt water and sodium are the usual issues near the coast, and nitrate where the water table is shallow; arsenic and radon from bedrock are less common.

Classification from the USGS Principal Aquifers of the United States (national map, 2003 edition, GIS release 2015), read at the town centroid. A single well can sit in a different unit, especially near a boundary.

Contamination sources on record in Middle township

NJDEP records 1 hazardous waste site in Middle township, among 160 regulated sites in total. Groundwater does not follow property lines, so a well within a few hundred feet of one of these is worth testing for what that site could release.

1: hazardous waste siteSolvents, degreasers and metals from industrial sites can travel far in fractured bedrock.
134: registered underground storage tank sitesRegistered tanks are regulated and inspected; they matter most when they are old or near a shallow well.
3: lined landfills and transfer facilities
22: other remediation projects

Standards are New Jersey's: arsenic 5 ug/L, PFOA 14 ng/L, PFOS 13 ng/L, PFNA 13 ng/L, manganese and iron secondary standards. Uranium and PFAS were added to the required panel in 2021 and 2020, so their well counts are smaller. Retrieved September 9, 2026.
