This system was not included in federal PFAS monitoring
FYI▾
Should I be concerned?
This system serves fewer than 3,300 people and was not required to participate in EPA UCMR5 testing. Absence of data is not the same as absence of contamination.
Lead risk depends on your home, not just the water system
Act soon▾
The concern isn't usually the treatment plant — it's pipes inside older homes. No level is considered safe for children under 6.
Should I be worried?
Not necessarily — but if your home was built before 1986, it's worth checking whether you have lead pipes or solder. Run cold water 30 seconds before drinking in the morning.

Contaminants detected above federal limits
Your utility's own 2025 water report disclosed the following levels. Utilities have until 2029 to comply with new federal limits.
Contaminant

Chlorite▸
0.02 mg/L
MCLlegally enforceable
What is it?
A byproduct of chlorine dioxide disinfection, used by some utilities as an alternative to chlorine.
Why it matters
Exposure above the MCL of 1.0 mg/L can cause anemia in infants and young children and nervous system effects.
What to do
No action needed at typical detection levels.
HAA5▸
47.7 µg/L
MCLlegally enforceable
Sample history
Range: 25.8 to 47.7 µg/L across 5 samples (Jan to Oct 2025).
Compliance for HAA5 is calculated as a locational running annual average (LRAA), not single samples. This system's LRAA was 36.56 µg/L, within the 60 µg/L MCL.
What is it?
Another group of disinfection byproducts formed when chlorine reacts with natural organic matter. HAA5 measures the five most common species.
Why it matters
Long-term exposure above the MCL of 60 µg/L (0.060 mg/L) is associated with increased cancer risk. Like THMs, the MCL is based on a running annual average.
What to do
Activated carbon filters can reduce HAA5. If your system consistently approaches the limit, a reverse osmosis filter provides more complete removal.
TTHM▸
93.2 µg/L ×1.2
MCLlegally enforceable
Sample history
Range: 25.5 to 93.2 µg/L across 5 samples (Jan to Oct 2025).
Compliance for TTHM is calculated as a locational running annual average (LRAA), not single samples. This system's LRAA was 56.93 µg/L, within the 80 µg/L MCL.
The high single-sample value is shown because brief exposures can matter for some health outcomes, even when annual averages remain compliant.
What is it?
Formed when chlorine used to disinfect water reacts with natural organic matter. Includes chloroform, bromoform, and related compounds. The trade-off: disinfection prevents waterborne disease, but creates these byproducts.
Why it matters
Long-term exposure above the MCL of 80 µg/L (0.080 mg/L) is associated with increased cancer risk and possible reproductive effects. The MCL is based on a running annual average, not a single sample.
What to do
If your system is near or above the limit, an activated carbon filter (including pitcher filters like Brita) can reduce THMs. Running water for a minute before drinking also helps, as THMs are volatile and dissipate.
