How this grade was calculated

This system received a grade of C because HFPO-DA was detected at 73% of the EPA Maximum Contaminant Level, approaching but not yet exceeding the federal limit.

Letter grade rubric
GradeCriteria
ANo PFAS detected above the Minimum Reporting Level
BPFAS detected, all below 50% of the EPA MCL
CWorst compound between 50% and 100% of EPA MCL
DAt least one compound exceeds the EPA MCL (up to 5×)
FAt least one compound exceeds 5× the EPA MCL

What WESTERN LEWIS RECTORVILLE WATER DISTRICT customers can do

WESTERN LEWIS RECTORVILLE WATER DISTRICT's water is approaching federal PFAS limits. Consider these steps:

  • Install a water filter certified to NSF/ANSI Standard 53 or 58 for PFAS reduction. Activated carbon pitchers or under-sink reverse osmosis systems both work.
  • Request your utility's most recent Consumer Confidence Report and ask specifically about PFAS testing.
  • Ask your utility what treatment changes are planned to reduce PFAS levels.
  • Sign up for water quality alerts and follow your utility's compliance reporting.
