Real EPA measurements of haloacetic acids (haa5) for South Dakota water systems — Six-Year Review compliance samples 2012–2019 (historical). Methodology
We can't tell you from federal data yet. Our EPA dataset (SDWIS violations, the Six-Year Review, Lead and Copper Rule and UCMR 5 results) does not currently include any South Dakota public water system, so this page has no South Dakota city measurements or violation records for haloacetic acids (haa5). That is a gap in our data, not evidence that South Dakota water is free of haloacetic acids (haa5) — or that it contains any.
To find the real number for your tap, read your utility's annual Consumer Confidence Report (every community water system must publish one by July 1), or test your water with a certified lab if you are on a private well.
Every South Dakota system with a haloacetic acids (haa5) result in EPA's data, sorted by level. Averages of 2012–2019 finished-water samples, non-detects counted as zero — historical, not today's tap.
No haloacetic acids (haa5) detections have been reported in South Dakota cities.
Haloacetic acids are disinfection byproducts formed when chlorine or other disinfectants react with organic matter. The EPA regulates five HAAs (HAA5): monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monobromoacetic acid, and dibromoacetic acid. Studies have linked HAAs to increased cancer risk and potential developmental and reproductive effects. Dichloroacetic acid in particular has been shown to cause liver cancer in laboratory animals.
Formed during water disinfection when chlorine reacts with organic compounds; levels vary with source water quality and treatment processes
Based on our analysis of EPA Safe Drinking Water Information System (SDWIS) data and local water utility reports,haloacetic acids (haa5) has been detected in 0 South Dakota water systems.
The EPA MCL for HAA5 is 60 ug/L (60 ppb). The EPA MCL for haloacetic acids (haa5) is 60 ug/L. This limit is set to protect public health based on available scientific evidence about the contaminant's health effects.
0 South Dakota cities have haloacetic acids (haa5) detected in their water supply. All tested cities are within EPA safety limits.
Increased cancer risk, potential liver damage, developmental effects. The most vulnerable groups include pregnant women and people with liver conditions.
The most effective methods for removing haloacetic acids (haa5) include Activated Carbon, Reverse Osmosis, Distillation. Look for filters certified by NSF/ANSI for haloacetic acids (haa5) reduction.
The EPA Maximum Contaminant Level (MCL) for haloacetic acids (haa5) is 60 ug/L.The EPA MCL for HAA5 is 60 ug/L (60 ppb).
This page shows what South Dakota utilities reported for haloacetic acids (haa5). It cannot tell you what is coming out of your own tap: utility samples are taken across a whole system and averaged, levels vary by address and season, and anything picked up after the water leaves the main never appears in their report.
