What is the Water Quality in Eastvale, California?
[Updated: June 10, 2023]
Compared to other US cities, Eastvale water quality ranks in the middle range for contamination excluding Lead.
Most of their 21 contaminants have cancer-causing attributes.
- Haloacetic acids (HAA5) are at very high levels: 50x health guidelines.
- Haloacetic acids (HAA9) are at extremely high levels: 161x health guidelines.
- These are both byproducts of the chlorine treatment process most water supplies go through.
Let’s look closer at what’s in Eastvale water.
What’s in Eastvale water?
Here are the top 6 chemical compounds in your water and what health issues they can potentially cause:
- Bromodichloromethane – Potential effect: Cancer
- Chloroform – Potential effect: Cancer
- Hexavalent Chromium – Potential effect: Cancer
- Haloacetic acids (HAA5) – Potential effect: Cancer
- Total trihalomethanes – Potential effect: Cancer
These are six of the 21 contaminants analyzed by the Environmental Working Group (ewg.org).
11 of these contaminants are rated as exceeding EWG Health Guidelines.
Does Eastvale have Lead contamination?
No, Eastvale does not currently have lead in its water. The most recent Lead samples collected in 2019 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.

Where does Eastvale’s water come from?
Eastvale’s water comes from the Lower Cucamonga Creek watershed.
Both water sources in the Lower Cucamonga Creek watershed are in Impaired condition. These are:
- Cucamonga Creek Reach 1

Conclusion – What Can You Do?
Information about water quality in Eastvale can be surprising.
But there are things you can do in your home to clean up your water.
- Test Your Water using Varify Home Test Kits or similar.
- 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 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 – irritant of the eyes and respiratory tract. “Exposure may cause damage to the central nervous system, liver and kidneys.”
- Haloacetic acids – byproduct of chlorination*
- Hexavalent chromium
- Total trihalomethanes – byproduct of chlorination*
- 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.
