  • Lithium (above EPA’s health benchmark) was found in eight of 8 samples, highest 75.9 ppb. Above EPA’s health reference level of 10 ppb, a screening level rather than an enforceable limit.

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

What was found

Highlighted: above the health goal, or EPA’s health benchmark where there is no goal. Circled: above the legal limit in at least one sample, or the action level. Every scale puts that line at its middle.

PFAS and lithium: EPA UCMR 5, samples taken from Feb. 16, 2023 to Nov. 28, 2023. Each blue tick on a scale is one sample where it was found.

75.9ppb

Highest of 8 samples; found in eight

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.

Tested and not found

Below EPA’s minimum reporting level in every sample taken from Feb. 16, 2023 to Nov. 28, 2023. Not found means not measured above that level, which is not the same as zero.

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 Military Hwy WSC Las Rusias’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. 16, 2023 to Nov. 28, 2023.

  • Get the utility’s own report

    Military Hwy WSC Las Rusias must send you a water quality report every year. It lists nitrate, arsenic and byproduct levels this page cannot.

    How to read it

  • Test your own tap for lead

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

    Lead in your water: what to do

  • Decide if you want a filter at all

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