Analysis

What to know about Rockaway Boro-1434's water

Rockaway Boro-1434 ranks #136 out of 435 cities in New Jersey for water quality, placing it mid-range in the state.

Rockaway Boro-1434 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.
