Contaminants found
Metals
Naturally occurring or corrosion-related elements, e.g. lead, arsenic, copper
Lead Summary
Detected: 0 mg/L (ppm)
12/31/2027
Iron
Detected: 210 UG/L (ppb)
10/6/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Manganese
Detected: 260 UG/L (ppb)
6/3/2025
Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.
Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
Dibromomethane
Detected: 0.5 UG/L (ppb)
5/5/2025
TTHM
Detected: 4 UG/L (ppb)
5/5/2025
A group of disinfection byproducts formed when chlorine reacts with organic matter. Long-term exposure above the legal limit has been linked to increased cancer risk in some studies.
Inorganics
Common dissolved minerals and salts, e.g. nitrate, fluoride, chloride
Chloride
Detected: 248 MG/L (ppm)

Sulfate
Detected: 467 MG/L (ppm)
10/16/2025
Nitrate
Detected: 5.7 MG/L (ppm)
10/27/2025
Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.
Properties
General water characteristics like pH, hardness, and cloudiness (turbidity)
pH
Detected: 7.5 PH
7/9/2025
A measure of how acidic or basic the water is (7 is neutral). Affects taste and plumbing, not a direct health measure.
