Read this first

  • Lead In the latest period, 9 in 10 homes sampled were at or below 9.0 ppb, below the 15 ppb action level. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

No health-based violations on file since 2016.

What handles it

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’s UCMR 5 did not sample this utility, so there are no federal PFAS or lithium results for it. Its own annual report lists what it tests for.

  2. In treatment

    No federal results for this stop. Disinfection byproduct, chlorine and fluoride levels are in City of Lakewood’s own annual report, which it must send you every year.

  3. In the pipes

    Lead and copper, from the homes the utility samples. Your own service line, solder and fixtures decide yours.

  4. Lead

    Above the health goal

    9.0ppb

    90th percentile, 2002

    In the latest period, 9 in 10 homes sampled were at or below 9.0 ppb, below the 15 ppb action level. The action level drops to 10 ppb on Nov. 1, 2027. EPA’s health goal for lead is zero.

    EPA SDWIS, lead and copper monitoring periods ending 2000 to 2002. The line stops at the latest period; each tick under it is an earlier one.

  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

Violations since 2016

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

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

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 City of Lakewood’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 no sampling at this utility.

What to do next

  1. About Lead

    What each marked result does to health, where it comes from, and the certification claim that addresses it.

  2. Read the utility’s own report

    City of Lakewood 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. Compare five-year costs

    What the filters certified for these results cost over five years, cartridges included.
