This system received a grade of D because PFOS exceeds the EPA Maximum Contaminant Level by 1.6×.

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 EL PASO WATER UTILITIES PUBLIC SERVICE B customers can do

EL PASO WATER UTILITIES PUBLIC SERVICE B's water exceeds federal PFAS limits. We recommend customers take action:

  • Install a reverse osmosis (RO) or activated-carbon water filter certified to NSF/ANSI Standard 53 or 58 for PFAS reduction. RO systems remove the widest range of PFAS compounds.
  • Do NOT boil your water to remove PFAS. Boiling concentrates them.
  • Request your most recent Consumer Confidence Report from your utility and ask when PFAS treatment will be installed.
  • Contact your local elected officials and water utility board to demand a remediation timeline.
  • Get independent water testing through services like Tap Score (mytapscore.com) if you want to verify your in-home levels.
  • Talk to your healthcare provider about PFAS exposure, especially if you are pregnant, nursing, or have young children.
