Read this first

  • PFOA was found in one of 2 samples, highest 6.4 ppt. Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.
  • PFOS was found in one of 2 samples, highest 4.3 ppt. Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.
  • Lithium was found in one of 2 samples, highest 31.5 ppb. Above EPA’s health reference level of 10 ppb, a screening level rather than an enforceable limit.
  • Lead In the latest period, 9 in 10 homes sampled were at or below 2.0 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.

11 health-based violations since 2016. Details are below.

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 UCMR 5 sampled this utility for 29 PFAS and lithium from April 10, 2024 to Oct. 2, 2024. Each tick under a result’s line is one sample where it was found, dated when you point at it.

    NSF’s PFAS claims are tested to below 20 ppt. EPA’s limit is 4.0 ppt, and EPA says no certification yet shows a filter reaching its levels.

  2. PFOA

    Above the legal limit

    6.4ppt

    Highest of 2 samples; found in one

    Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.

    • NSF/ANSI 53 · Look for: PFOA ReductionSame claim, other certifiers’ wording: Total PFAS Reduction; Perfluorooctanoic Acid (PFOA)

    • NSF/ANSI 58 · Look for: Perfluorooctanoic Acid (PFOA)

  3. PFOS

    Above the legal limit

    4.3ppt

    Highest of 2 samples; found in one

    Above the 4.0 ppt legal limit in at least one sample. Compliance is judged on a running annual average, not one sample.

    • NSF/ANSI 53 · Look for: PFOS ReductionSame claim, other certifiers’ wording: Total PFAS Reduction; Perfluorooctane Sulfonate (PFOS)

    • NSF/ANSI 58 · Look for: Perfluorooctane Sulfonate (PFOS)

  4. Lithium

    Above EPA’s health benchmark

    31.5ppb

    Highest of 2 samples; found in one

    Above EPA’s health reference level of 10 ppb, a screening level rather than an enforceable limit.

    What handles it: No certification claim covers this compound yet.

  5. 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.

    CompoundHighest sampleFound inCertification claim
    PFPeA5.1 ppt1 of 2None covers it
    PFHxA3.3 ppt1 of 2None covers it

  6. In treatment

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

  7. In the pipes

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

  8. Lead

    Above the health goal

    2.0ppb

    90th percentile, 2023 to 2025

    In the latest period, 9 in 10 homes sampled were at or below 2.0 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 2004 to 2025. The line stops at the latest period; each tick under it is an earlier one.

  9. 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 April 10, 2024 to Oct. 2, 2024. Not found means not measured above that level, which is not the same as zero.

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.”

  • NSF/ANSI 53

    Claims: PFOA Reduction, PFOS Reduction, Lead Reduction

    For: PFOA, PFOS, Lead

  • NSF/ANSI 58

    Claims: Perfluorooctanoic Acid (PFOA), Perfluorooctane Sulfonate (PFOS), Lead Reduction

    For: PFOA, PFOS, 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 Village of Parks Water System’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 April 10, 2024 to Oct. 2, 2024.

What to do next

  1. Start with PFOA

    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

    Village of Parks Water System 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.
