Lead Summary
Detected: 0 mg/L (ppm)
12/31/2024
Iron
Detected: 38 UG/L (ppb)
5/28/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Chromium, Hex
Detected: 0.4 UG/L (ppb)
5/29/2025
Arsenic
Detected: 6 UG/L (ppb)
8/5/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
Disinfection Byproducts
Formed when chlorine used to disinfect water reacts with organic matter
Totalhaloaceticacids (HAA5)
Detected: 6 UG/L (ppb)
9/30/2025
TTHM
Detected: 8 UG/L (ppb)
9/30/2025
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.
Bromoform
Detected: 4 UG/L (ppb)
9/30/2025
Dibromochloromethane
Detected: 3 UG/L (ppb)
9/30/2025
Bromodichloromethane
Detected: 1 UG/L (ppb)

Inorganics
Common dissolved minerals and salts, e.g. nitrate, fluoride, chloride
Nitrate
Detected: 7.9 MG/L (ppm)
10/14/2025
Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.
Fluoride
Detected: 0.1 MG/L (ppm)
7/8/2025
Often added deliberately for dental health; can also occur naturally.
Properties
General water characteristics like pH, hardness, and cloudiness (turbidity)
Gross Alpha Particle Activity
Detected: 2.53 PCI/L
7/8/2025
pH
Detected: 6.8 PH
5/29/2025
A measure of how acidic or basic the water is (7 is neutral). Affects taste and plumbing, not a direct health measure.
