Analysis

What to know about Ramapo (T)'s water

Ramapo (T) ranks #725 out of 855 cities in New York for water quality, placing it among the lowest-rated in the state.

Ramapo (T) 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.

Hexavalent chromium (chromium-6) was detected at 0.12 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.

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.

Where Ramapo (T)'s water comes from

Groundwater

Ramapo (T)'s drinking water is drawn from underground aquifers through wells.

Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals.

Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds.

The system is operated by local government ownership and serves approximately 13,440 people through 7 water systems.

Frequently asked questions

Is Ramapo (T), NY tap water safe to drink?

Ramapo (T)'s water quality earned a grade of C+ (67.7/100). Some concerns have been identified. Consider a water filter for an extra layer of protection. The city ranks #725 out of 855 cities tested in New York.

What contaminants are in Ramapo (T)'s water?

Lead was measured at 6.0 ppb (90th percentile). 4 PFAS compounds were detected. 50 violations are on record.

How is Ramapo (T)'s water quality grade calculated?

The grade is based on four factors: violation history (40%), lead and copper levels (25%), PFAS contamination (25%), and regulatory compliance (10%). The score is also adjusted based on how complete the available data is. See our methodology page for full details.

Do I need a water filter in Ramapo (T)?

While lead levels are within EPA limits, a filter adds extra protection. PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.

Where does Ramapo (T)'s water come from?

Ramapo (T)'s water is sourced from Groundwater. The city has 7 water systems serving approximately 13,440 residents.

What health violations has Ramapo (T)'s water system had?

Ramapo (T) has 19 health-based violations on record. The most recent violation was recorded in October 2024. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 17 violations remain unresolved.

Is Ramapo (T)'s groundwater at risk of contamination?

Ramapo (T) uses groundwater, which can be affected by naturally occurring contaminants like arsenic, radon, and nitrate, as well as agricultural runoff and industrial activity. The system has 50 violations on record that may relate to groundwater quality. Groundwater systems are generally less susceptible to surface contamination but should be monitored for emerging contaminants like PFAS.

Why does Ramapo (T) have so many PFAS compounds in its water?

4 different PFAS "forever chemical" compounds were detected in Ramapo (T)'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 Ramapo (T)'s water compare to other cities?

Ramapo (T) ranks #725 out of 855 cities in New York (better than 15% of state cities) and #11191 out of 15744 cities nationally (29th percentile). The grade of C+ reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
