What is the Water Quality in Carson, California?
Compared to other US cities over 50,000, Carson water quality ranks in the high range for contamination excluding Lead.
Most of their 36 contaminants have cancer-causing attributes. Arsenic is at high levels: 36x health guidelines.
Let’s look closer at what’s in Carson water.
What’s in Carson water?
Here are the top 5 chemical compounds in your water and what health issues they can potentially cause:
- Arsenic – Potential effect: Cancer
- Chloroform – Potential effect: Cancer
- Haloacetic acids – Potential effect: Cancer
- Hexavalent Chromium – Potential effect: Cancer
- Total trihalomethanes – Potential effect: Cancer
These are five of the 36 contaminants analyzed by the Environmental Working Group (ewg.org).
12 of these contaminants are rated as exceeding EWG Health Guidelines.
Does Carson have Lead contamination?
No, Carson does not currently have lead in its water. The most recent Lead samples collected from 2015 through 2017 showed concentrations of 0.0 parts per billion.
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.
See the What Can You Do? section below to learn how to filter out contaminants.
Where does Carson’s water come from?
Carson’s water comes from the Lower Dominguez Channel watershed.
5 of the 7 EPA assessed water sources in the Lower Dominguez Channel watershed are in Impaired or Unknown condition. These include:
- Alondra Park Lake
- Dominguez Channel
- Dominguez Channel Estuary
- Los Angeles Harbor
- Torrance Carson Channel
Ideally, a water source would be rated in Good condition. Del Amo Channel and Los Angeles Project No. 5246 are in Good condition.
Whether a water source is in Impaired or Good condition refers to the quality of these uses:
- Drinking Water
- Aquatic Life
- Fish and Shellfish Consumption

Conclusion – What Can You Do?
Information about water quality in Carson, California can be surprising.
But there’s no reason to lose hope. There are things you can do in your household as well as things you can do at a community level.
- Use Berkey filters with activated carbon to filter out at least 81.5% of contaminants in your drinking water. (Berkey Light and Travel Berkey are the only types available in California.)
- Berkey filters can also remove up to 99.99% of Lead in Carson water.
- Brita can filter 19 contaminants and Lead depending on the filter.
- Note: We may receive a commission if you decide to purchase filters through links on this page.
- To filter out 33 of the 36 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:
- Arsenic – health risks
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Selenium – health risks
- Total trihalomethanes – byproduct of chlorination*
*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.
