Water Quality Summary
Austin is served by 616 public water systems with a combined service population of 1,788,805 people, and has 12,912 EPA Safe Drinking Water Act violations on record. Critically, 1147 of those are health-based violations, meaning one or more contaminants were detected above EPA-established safe levels — a serious public health concern. Austin's violation count is 5974% above the national average for Texas. Contaminants associated with violations include Barium, Bromate, Chlorine Dioxide, Disinfection Byproducts, E. coli.
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
Bromate
Probable human carcinogen that increases the risk of kidney and thyroid cancers.
Common source: Ozonation of bromide-containing water; used as flour improver
EPA limit: 0.010 mg/L (10 ppb)
Chlorine Dioxide
Can cause anemia in infants and young children; may cause nervous system effects at high levels.
Common source: Water treatment disinfectant used to control taste, odor, and microorganisms
EPA limit: 0.8 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
E. coli
Causes gastrointestinal illness; certain strains (e.g., O157:H7) can cause severe kidney failure and death.
Common source: Fecal contamination from humans or animals entering the water supply
EPA limit: Zero (no E. coli permitted in drinking water)
Fecal Coliform
Indicates direct fecal contamination; associated with diarrhea, cramps, nausea, and potential severe illness.
Common source: Human and animal fecal waste
EPA limit: Zero tolerance (any positive triggers violations)
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)
Haloacetic Acids
Linked to increased cancer risk and potential reproductive and developmental effects with long-term exposure.
Common source: Reaction of chlorine disinfectants with organic matter in treated water
EPA limit: 0.060 mg/L (60 ppb)
Lead
Causes neurological damage, developmental delays in children, and kidney damage in adults even at low exposure levels.
Common source: Old plumbing pipes, lead solder, brass fixtures
EPA limit: Action Level: 0.015 mg/L (15 ppb)
Selenium
Hair loss, nail brittleness, and nervous system damage at elevated concentrations.
Common source: Natural geological deposits, mining discharges, oil refinery waste
EPA limit: 0.05 mg/L (50 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
TTHM
Total trihalomethanes are linked to increased risk of bladder cancer and adverse reproductive outcomes.
Common source: Reaction of chlorine disinfectants with naturally occurring organic matter in water
EPA limit: 0.080 mg/L (80 ppb)
Total Haloacetic Acids (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)
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)
