What is the Water Quality in Monterey Park, California?

Compared to other US cities, Monterey Park water quality ranks in the high range for contamination excluding Lead.

Most of their 37 contaminants have cancer-causing attributes.

  • Arsenic is at extremely high levels: 344x health guidelines.
  • PFOA is at extremely high levels: 442x health guidelines.
  • PFOS is at very high levels: 7x health guidelines.
    • PFOA and PFOS are considered “forever chemicals” based on how difficult it is to break them down to safe levels. PFOA has been linked to cancer.

Let’s look closer at what’s in Monterey Park water.

What’s in Monterey Park water?

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

  1. Arsenic – Potential effect: Cancer
  2. Hexavalent Chromium – Potential effect: Cancer
  3. Haloacetic acids (HAA5 and HAA9) – Potential effect: Cancer
  4. PFOA – Potential effect: Cancer
  5. Uranium – Potential effect: Cancer

These are five of the 37 contaminants analyzed by the Environmental Working Group (ewg.org).

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

Does Monterey Park have Lead contamination?

Yes, Monterey Park has lead in its water. The most recent Lead samples collected from 2018 through 2020 showed concentrations up to 0.7 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 filtered out.

See the What Can You Do? section below to learn how to filter out contaminants.

Where does Monterey Park’s water come from?

Monterey Park’s water comes from the Chavez Ravine – Los Angeles River watershed.

The 4 assessed water sources in the Chavez Ravine – Los Angeles River watershed are in Impaired or Unknown condition. These include:

  • Belvedere Park Lake
  • Hollenback Park Lake
  • Lincoln Park Lake
  • Los Angeles River Reach 2 (Carson to Figueroa Street)

Ideally, a water source would be Known and rated in Good condition.

Whether a water source is in Impaired or Good condition refers to the quality of three uses:

  1. Aquatic Life
  2. Fish and Shellfish Consumption
  3. Recreation

Conclusion – What Can You Do?

Information about water quality in Monterey Park can be surprising.

But there’s no reason to lose hope. There are things you can do in your home as well as things you can do at a community level.

In Your Home:
Take Control of Your Water with Berkey Filters

  • Use Berkey filters with activated carbon to filter out at least 85% 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 Monterey Park water.
      • They will also remove Arsenic, HAA5, HAA9, PFOA, and PFOS.
    • Brita can filter 23 of 37 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 34 of the 37 contaminants, consider a Reverse Osmosis Pentair 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:
      • Arsenic
      • Bromodichloromethane
      • Chloroform
      • Chromium (total)
      • Fluoride
      • Haloacetic acids (HAA5 and HAA9) – byproduct of chlorination*
      • Hexavalent chromium
      • Molybdenum
      • NDMA
      • Nitrate
      • PFBS
      • PFDA
      • PFHPA
      • PFHxA
      • PFHXS
      • PFNA
      • PFOA
      • PFOS
      • Strontium
      • Total trihalomethanes – byproduct of chlorination*
      • 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.
