- Haloacetic acids (HAA5) are at extremely high levels: 276x health guidelines.
- Haloacetic acids (HAA9) are at extremely high levels: 460x health guidelines.

Let’s look closer at what’s in Bristol water.
What’s in Bristol water?
Here are the top 5 chemical compounds in your water and what health issues they can potentially cause:
- Bromodichloromethane – Potential effect: Cancer
- Chloroform – Potential effect: Cancer
- Haloacetic acids (HAA5) – Potential effect: Cancer
- Haloacetic acids (HAA9) – Potential effect: Cancer
- Total trihalomethanes – Potential effect: Cancer
These are five of the 21 contaminants analyzed by the Environmental Working Group (ewg.org).
11 of these contaminants are rated as exceeding EWG Health Guidelines.
Does Bristol have Lead contamination?
No, Bristol does not currently have lead in its water. The most recent Lead samples collected in 2018 showed concentrations of 0.0 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 filtered out.

Where does Bristol’s water come from?
Bristol’s water comes from the Pequabuck River watershed.
8 of the 14 assessed water sources in the Pequabuck River watershed are in Impaired or Unknown condition. These include:
- Pequabuck River – Multiple sections
- Poland River – Multiple sections
Ideally, a water source would be rated in Good condition. Birge Pond, Pine Lake, Powder Brook, and South Mountain Brook are all in Good condition.
Whether a water source is in Impaired, Unknown, or Good condition refers to the quality of three uses:
- Aquatic Life
- Fish and Shellfish Consumption

What Can You Do?
Information about water quality in Bristol 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:
There is one solution that beats Brita, PUR, and expensive whole house systems.
- It costs less per gallon.
- Needs fewer filter changes.
- And it doesn’t make your water taste weird.
- Use Berkey filters with activated carbon to filter out at least 83% of contaminants in your drinking water.
- To filter out 18 of the 21 contaminants, consider a Reverse Osmosis water filtration system for your house.
- These are more expensive than pitchers to purchase, but are more effective.
- They have the benefit of filtering out heavy hitters like:
*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.
