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

What Else is in Anaheim water?

Here are the top 5 chemical compounds in your water and what health issues they can potentially cause:

  1. Bromodichloromethane – Potential effect: Cancer
  2. Chloroform – Potential effect: Cancer
  3. Hexavalent Chromium – Potential effect: Cancer
  4. Total trihalomethanes – Potential effect: Cancer
  5. Uranium – Potential effect: Cancer

These are five of the 39 contaminants analyzed by the Environmental Working Group (

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

Does Anaheim have Lead contamination?

Yes, Anaheim has lead in its water. The most recent Lead samples collected from 2016 through 2018 showed concentrations up to 2.0 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.

There is one solution that beats Brita, PUR, and expensive whole house systems.

  • It costs less per gallon.
  • Needs fewer filter changes.
  • And it doesn’t make your water taste weird.

Take Control of Your Water with Berkey Filters

  • Use Berkey filters with activated carbon to filter out at least 75% 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 Anaheim water.
    • Brita can filter 21 contaminants (53%) 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 34 of the 39 contaminants (87%), consider a Reverse Osmosis water filtration system for your house.

*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.
