Fresno Water Quality Issues

Does Fresno have water quality issues?

Fresno water quality ranks in the high range for contaminants. With a total of 53 contaminants in your drinking water, 17 of them exceed health guidelines.

  • For reference, Miramar, Florida has 75 contaminants. (The most of any U.S. city over 50,000.)

Drinking unfiltered water from Fresno water sources could be hazardous to your health.

Let’s look closer at Fresno water quality.

Fresno Water Contamination

Fresno has a total of 53 contaminants analyzed by the Environmental Working Group (

32.1% of contaminants are rated as exceeding health guidelines.

They include things like:

  • Arsenic
  • Chromium
  • PFOA
  • PFOS
  • Radium
  • Uranium

Most of the contaminants pose a risk of Cancer if allowed to stay in your drinking water.

Lead in Fresno Water

Fresno drinking water has very low levels of lead in it.

90 percent of samples taken from Fresno water sources from January 2018 – June 2018 had a lead concentration of 0.0 parts per billion (ppb) or less.

For comparison:

  • Lead concentrations of 3.9 ppb to 15 ppb “put a formula-fed baby at risk of elevated blood lead levels.” (
  • El Paso, Texas has lead concentrations up to 84 parts per billion.
  • Portland, Oregon has lead concentrations up to 52.4 parts per billion.
  • The legal limit for lead is 15 ppb. The city is not legally required to mitigate unless levels pass 15 ppb.

There is no safe level of lead for humans.

Here are a few of the lead poisoning symptoms for children under 6:

  1. Abdominal Pain
  2. Developmental Delay
  3. Learning Difficulties
  4. Fatigue
  5. Weight loss
  6. Irritability

So, What Can You Do?

Information about water quality can be surprising.

There are things you can do today to keep you and your family safe and healthy.

In Your Household:

Use Berkey water filters with activated carbon to filter out at least 72.5 percent of contaminants in your drinking water.

(They also remove up to 99% of lead contamination in Fresno water.)

Basic pitchers like Brita can filter 52.5%. Brita Longlast filters and faucet filters can also remove Lead.

Fresno Whole House Water Filtration Systems

A whole house filtration system can filter out 87.5 percent or better, making it another effective choice.

A few things to note:

  • Whole house systems are much more effective than water pitchers like Brita and PUR.
  • However, the initial cost is higher and they require installation.

For a list of the contaminants that can be filtered out by a whole house system, go to Fresno’s Water Quality page.
