Contaminants Found

Barium

Increases blood pressure and causes cardiovascular effects with long-term exposure.

Common source: Natural rock deposits, oil drilling operations, coal power plant waste

EPA limit: 2 mg/L

Disinfection Byproducts

Broad category of chemicals formed during disinfection, associated with increased cancer risk and adverse reproductive effects.

Common source: Reaction of disinfectants (chlorine, ozone, chloramines) with organic matter

Gross Alpha

Alpha-emitting radioactive particles increase cancer risk, particularly from bone and other internal cancers.

Common source: Natural uranium and radium in geological formations

EPA limit: 15 pCi/L (excluding radon and uranium)

HAA5

Haloacetic acids are associated with increased cancer risk and potential reproductive and developmental effects.

Common source: Reaction of chlorine disinfectants with organic matter in treated water

EPA limit: 0.060 mg/L (60 ppb)

Stage 2 DBP

Trihalomethanes and haloacetic acids that increase cancer risk and may cause adverse reproductive outcomes.

Common source: Chlorine disinfection reacting with natural organic matter in source water

EPA limit: TTHM: 0.080 mg/L; HAA5: 0.060 mg/L

Total Organic Carbon

Not a direct health risk but reacts with disinfectants to form carcinogenic byproducts such as trihalomethanes.

Common source: Decaying plant material, algae, soil organic matter in source water

EPA limit: Treatment technique (must reduce TOC based on source water level)

Concerned About Your Water?

A home water filter can remove common contaminants. NSF-certified filters are tested against EPA standards.

Consider a reverse osmosis system for comprehensive filtration or a carbon filter for basic improvement.
