Real EPA measurements of chromium 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 chromium. That is a gap in our data, not evidence that South Dakota water is free of chromium — 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 chromium 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 chromium detections have been reported in South Dakota cities.
Chromium-6 (hexavalent chromium) is a known human carcinogen when inhaled. When ingested through drinking water, chromium-6 has been shown to cause cancer in laboratory animals. Health effects include damage to the liver, kidney, and gastrointestinal and immune systems. California has proposed a specific MCL of 10 ppb for chromium-6, much lower than the federal total chromium standard.
Discharge from steel and pulp mills; erosion of natural deposits; industrial pollution
Based on our analysis of EPA Safe Drinking Water Information System (SDWIS) data and local water utility reports,chromium has been detected in 0 South Dakota water systems.
The EPA MCL for total chromium is 0.1 mg/L (100 ppb). The EPA MCL for chromium is 0.1 mg/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 chromium detected in their water supply. All tested cities are within EPA safety limits.
Potential carcinogen, liver and kidney damage, gastrointestinal effects. The most vulnerable groups include children and people with kidney disease.
The most effective methods for removing chromium include Reverse Osmosis, Strong Base Anion Exchange. Look for filters certified by NSF/ANSI for chromium reduction.
The EPA Maximum Contaminant Level (MCL) for chromium is 0.1 mg/L.The EPA MCL for total chromium is 0.1 mg/L (100 ppb).
This page shows what South Dakota utilities reported for chromium. 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.
