What individual samples found
Each row summarizes every public sample for that contaminant inside Deptford 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 1980 to 1986 | 10 | 60% | 0 | 0.14 | 10 mg/L EPA limit | |
| Sodium 1951 to 2009 | no limit | 22 | 100% | 38 | 79 | 20 mg/L health guideline |
| Iron 1951 to 2009 | no limit | 19 | 100% | 160 | 2,000 | 300 ug/L nuisance level |
| Manganese 1951 to 2009 | no limit | 18 | 94% | 4 | 210 | 300 ug/L health guideline |
Sampled fewer than 10 times, too few to summarize: Lead (8), Arsenic (5), Chloride (1).

Among homeowners in Deptford township who sent a sample to the state lab, the health-based limits most often exceeded were total coliform (29% of 70 wells), PFOA (5% of 20 wells), and arsenic (3% of 33 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.
Iron and manganese 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 Deptford 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.

Share of private wells exceeding each standard in tests required at sale or lease under the New Jersey Private Well Testing Act, September 2002 to December 2024, published by NJDEP. Tests are untreated water at the time of sale or lease, so every well is counted once per transaction. Municipalities with fewer than ten wells are suppressed. 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.

Non-detects count as samples and are treated as zero when computing medians. Exactly at the limit counts as not above it. A sample belongs to the town containing the well's reported coordinates.
