PWSID CA0910001 · EPA data

Read this first

Nothing in the federal data for this utility is above a health goal. That covers PFAS, lithium, lead and copper; it does not cover everything, so read what this report cannot tell you below.

No health-based violations on file since 2016.

What was found, stop by stop

  • Below the health goal
  • Above the health goal
  • Above the legal limit
  • No federal data

  1. At the source

    EPA UCMR 5 sampled this utility for 29 PFAS and lithium from Feb. 7, 2023 to May 8, 2024. Each tick under a result’s line is one sample where it was found, dated when you point at it.

  2. Also found, with no federal limit

    EPA measured these PFAS to learn how often they occur. None has a legal limit or a health goal yet.

  3. In treatment

    No federal results for this stop. Disinfection byproduct, chlorine and fluoride levels are in El Dorado ID - Main’s own annual report, which it must send you every year.

  4. In the pipes

    No lead and copper results on file with EPA for this utility.

  5. At your tap

    The last stretch is your own plumbing. A certified lab test is the only way to know what reaches your glass. Lead in your water: what to do

Tested and not found

Below EPA’s minimum reporting level in every sample taken from Feb. 7, 2023 to May 8, 2024. Not found means not measured above that level, which is not the same as zero.

Violations since 2016

No health-based violations on file with EPA since 2016.

What this report cannot tell you

  • Levels of everything else. Federal bulk data carries results for PFAS, lithium, lead and copper, and violations for the rest. Nitrate, arsenic, disinfection byproducts and other levels are in El Dorado ID - Main’s own annual report, which it must send you every year.
  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.
  • Anything after the latest data. SDWIS data is from 2026 Q2; UCMR 5 samples are from Feb. 7, 2023 to May 8, 2024.

What to do next

  1. Every contaminant TapBuff tracks

    Nothing here is above a health goal in the federal data, which does not cover everything.

  2. Read the utility’s own report

    El Dorado ID - Main must send you a water quality report every year. It lists nitrate, arsenic and byproduct levels this page cannot.

  3. Test your own tap for lead

    Your service line, solder and fixtures decide the lead at your faucet, not the utility’s average.

  4. NSF/ANSI standards, decoded

    A filter for taste or chlorine is a preference, not a need. The standards say what each kind can do.
