What is the Water Quality in New Rochelle, New York?
[Updated: June 9, 2023]
Compared to other US cities, New Rochelle water quality ranks in the middle range for contamination excluding Lead.
Most of their 22 contaminants have cancer-causing attributes.
- Chloroform is at very high levels: 83x health guidelines.
- Haloacetic acids (HAA5) are at extremely high levels: 264x health guidelines.
- Haloacetic acids (HAA9) are at extremely high levels: 431x health guidelines.
- These are both byproducts of the chlorine treatment process most water supplies go through.
Let’s look closer at what’s in New Rochelle water.
What’s in New Rochelle water?
Here are the top 5 chemical compounds in New Rochelle water and what health issues they can potentially cause:
- Chloroform – Potential effect: Cancer
- Haloacetic acids (HAA5) – Potential effect: Cancer
- Haloacetic acids (HAA9) – Potential effect: Cancer
- Hexavalent Chromium – Potential effect: Cancer
- Total trihalomethanes – Potential effect: Cancer
These are five of the 22 contaminants analyzed by the Environmental Working Group (ewg.org).
9 of these contaminants are rated as exceeding EWG Health Guidelines.
Does New Rochelle water have Lead contamination?
Yes, New Rochelle has lead in its water. The most recent Lead samples collected from 2016 through 2018 showed concentrations up to 6.5 parts per billion (ppb).
The legal limit for lead is 15 parts per billion. Being well-below this level is a good thing.
- Concentrations between 3.8 ppb and 15 ppb put a formula-fed baby at risk of elevated blood lead levels. Read more about the symptoms of Lead in water.
There is no safe level of lead for humans.
- The good news is that 99.99% of the lead can be removed.

What Can You Do?
Information about water quality in New Rochelle can be surprising.
But there are things you can do in your home to clean up your water.
To Remove Lead and Other Contaminants In Your Home:
- Use Activated Carbon filters to remove most contaminants in your drinking water.
- To filter out even more contaminants, consider a Reverse Osmosis water filtration system for your house.
- These are more expensive than pitchers to purchase, but can be more effective.
- They have the benefit of filtering out heavy hitters like:
- Barium – health risks in water
- Bromodichloromethane – health risks in drinking water
- Chloroform – side effects
- Chromium (total)
- Dichloroacetic acid
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Pentachlorophenol – toxicity
- Total trihalomethanes – byproduct of chlorination*
- Trichloroacetic acid
- Our recommendation: APEC Reverse Osmosis Systems
*Chlorination is an effective method of disinfecting/treating drinking water. You can then use a water filter to reduce the effects of chlorination byproducts to get the safest, cleanest water possible.
