What to know about Wharton Boro-1439's water
Wharton Boro-1439 ranks #189 out of 435 cities in New Jersey for water quality, placing it mid-range in the state.
Wharton Boro-1439 relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.
Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.
While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection.

Why does Wharton Boro-1439 have so many PFAS compounds in its water?
4 different PFAS "forever chemical" compounds were detected in Wharton Boro-1439's water supply during UCMR 5 testing. PFAS contamination often originates from proximity to military installations (AFFF firefighting foam), airports, industrial manufacturing sites, or wastewater treatment facilities. Some levels exceed the 2024 EPA maximum contaminant levels — a reverse osmosis or NSF-certified activated carbon filter is strongly recommended.
How does Wharton Boro-1439's water compare to other cities?
Wharton Boro-1439 ranks #189 out of 435 cities in New Jersey (better than 57% of state cities) and #9501 out of 15744 cities nationally (40th percentile). The grade of B reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
