What is the water quality like in Santa Ana, CA?

Let’s dive deeper into what’s in Santa Ana water.

What’s in Santa Ana water?

Here are the top 7 chemical compounds in your 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
  7. Uranium – Potential effect: Cancer

These are seven of the 25 contaminants analyzed by the Environmental Working Group (ewg.org).

14 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.

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 19 of the 25 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 Santa Ana water.
    • Brita can filter 13 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 23 of the 25 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 – “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.
      • Bromide
      • Bromodichloromethane – health risks in drinking water
      • Bromoform
      • Chloroform – side effects
      • Dibromoacetic acid
      • Dibromochloromethane
      • Dichloroacetic acid
      • Fluoride
      • Haloacetic acids – chlorination byproduct*
      • Hexavalent chromium – health effects
      • Molybdenum
      • Monochloroacetic acid
      • Nitrate
      • Nitrite
      • Perchlorate – used as oxidizers in propellants for rockets, fireworks, and highway flares. Also used to control static electricity in food packaging.
      • Strontium
      • Total trihalomethanes – byproduct of chlorination*
      • Trichloroacetic acid
      • Uranium

*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.
