• Haloacetic acids (HAA5) are at extremely high levels: 125x health guidelines.
• Haloacetic acids (HAA9) are at extremely high levels: 195x health guidelines.
  • These are both byproducts of the chlorine treatment process most water supplies go through.
• PFOA is at very high levels: 13x health guidelines.
  • Perris has PFAS chemicals: PFHXS, PFOA, and PFOS.

Let’s look closer at what’s in Perris water.

What’s in Perris water?

Here are the top 6 chemical compounds in Perris water and what health issues they can potentially cause:

1. Arsenic – Potential effect: Cancer
2. Bromodichloromethane – Potential effect: Cancer
3. Chloroform – Potential effect: Cancer
4. Haloacetic acids – Potential effect: Cancer
5. Hexavalent Chromium – Potential effect: Cancer
6. Total trihalomethanes – Potential effect: Cancer

These are six of the 33 contaminants analyzed by the Environmental Working Group (ewg.org).

15 of these contaminants are rated as exceeding EWG Health Guidelines.

Does Perris water have Lead contamination?

No, Perris does not currently have lead in its water. The most recent Lead samples collected from 2014 through 2016 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 removed.

Conclusion – What Can You Do?

Information about water quality in Perris can be surprising.

But there are things you can do in your home to clean up your water.

1. Test Your Water using Varify Home Test Kits or similar.
2. To Remove Lead and Other Contaminants In Your Home:

• Use Activated Carbon filters to remove most contaminants in your drinking water.
  • Faucet-mount filters work better than pitchers.
  • PUR and Brita are low-cost and effective.

• 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:
    • 1,4-Dioxane
    • Aluminum
    • Arsenic – health risks
    • Barium – health risks in water
    • Bromodichloromethane – health risks in drinking water
    • Bromoform
    • Chloroform – side effects
    • Dibromoacetic acid
    • Dibromochloromethane
    • Fluoride
    • Haloacetic acids – chlorination byproduct*
    • Hexavalent chromium – health effects
    • Molybdenum
    • Nitrate
    • Nitrite
    • Strontium
    • Total trihalomethanes – byproduct of chlorination*
    • Trichloroacetic acid
    • Uranium
  • 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.
