Lead And Copper Rule Revisions

Currently open health violation

Found at 2 of 57 providers

Contaminants found

Metals

Naturally occurring or corrosion-related elements, e.g. lead, arsenic, copper

Lead Summary

Detected: 0.0089 mg/L (ppm)

Found at 8 providers

Chromium, Hex

Detected: 0.75 UG/L (ppb)

Found at 5 providers

Lead

Detected: 27 UG/L (ppb)

Found at 2 providers

A metal that can leach from old pipes, solder, and fixtures. Current medical guidance holds there is no truly safe level of lead exposure, especially for children and pregnant women.

Copper, Free

Detected: 1600 UG/L (ppb)

Found at 2 providers

Manganese

Detected: 55 UG/L (ppb)

Found at 2 providers

Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.

Iron

Detected: 440 UG/L (ppb)

7/2/2025

Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.

Aluminum

Detected: 120 UG/L (ppb)

7/2/2025

Disinfection Byproducts

Formed when chlorine used to disinfect water reacts with organic matter

Totalhaloaceticacids (HAA5)

Detected: 60.6 UG/L (ppb)

7/2/2025

TTHM

Detected: 64.45 UG/L (ppb)

7/2/2025

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.

Chloroform

Detected: 63.45 UG/L (ppb)

7/2/2025

One of the individual trihalomethane disinfection byproducts, formed when chlorine reacts with organic matter.

Bromodichloromethane

Detected: 1 UG/L (ppb)

7/2/2025

Inorganics

Common dissolved minerals and salts, e.g. nitrate, fluoride, chloride

Nitrate

Detected: 1.5 MG/L (ppm)

Found at 10 providers

Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.
