Water Quality in Stockton, California
Watershed: McLeod Lake – Mormon Slough
What is the water quality like in Stockton, CA?
Let’s dive deeper into what’s in Stockton water.
What’s in Stockton water?
Here are the top 6 chemical compounds in your water and what health issues they can potentially cause:
- Arsenic – Potential effect: Cancer
- Bromodichloromethane – Potential effect: Cancer
- Chloroform – Potential effect: Cancer
- Haloacetic acids – Potential effect: Cancer
- Hexavalent Chromium – Potential effect: Cancer
- Total trihalomethanes – Potential effect: Cancer
These are six of the 36 contaminants analyzed by the Environmental Working Group (ewg.org).
13 of these contaminants are rated as exceeding EWG Health Guidelines.
See the What Can You Do? section below for all of the contaminants you can filter out and how to do it.
Where does Stockton’s water come from?
Stockton’s water comes from the McLeod Lake – Mormon Slough watershed.
One of the two EPA assessed water sources in the McLeod Lake – Mormon Slough watershed are in Impaired condition. This is:
- Mormon Slough from Stockton Diverting Canal to Bellota Weir.
Ideally, a water source would be rated in Good condition. The Stockton Diverting Canal itself is in Good condition.
Whether a water source is in Impaired or Good condition refers to the quality of these uses:
- Drinking Water

Conclusion – What Can You Do?
Information about water quality 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.
In Your Household:
- Use Berkey filters with activated carbon to filter out 32 of the 36 contaminants in your drinking water. (Berkey Light and Travel Berkey are the only types available in California.)
- To filter out 32 of the 36 contaminants in your whole house, consider a Reverse Osmosis water filtration system for your home.
- These are more expensive than pitchers to purchase, but can be more effective.
- They have the benefit of filtering out heavy hitters like:
- 1,4-Dioxane – “Exposure may cause damage to the central nervous system, liver and kidneys.”
- Arsenic – health effects in water
- Barium – In low doses, barium ions act as a muscle stimulant, and higher doses affect the nervous system, causing cardiac irregularities, tremors, weakness, anxiety, shortness of breath, and paralysis.
- Bromodichloromethane – health risks in drinking water
- Chloroform – side effects
- Chromium (total)
- Dibromoacetic acid
- Dichloroacetic acid
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Selenium – toxicity
- Total trihalomethanes – byproduct of chlorination*
- Trichloroacetic acid
*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.
In Your Community:
Contact your local government officials and put pressure on them to invest in cleaner waterways and upgraded city water filtration and treatment.
