National Drinking Water Database
Country Club Estates - ,
Serves 52 people - Test data available: 2005-2009
This drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group (EWG) by the South Dakota Department of Environment & Natural Resources. It is part of EWG's national database that includes 47,667 drinking water utilities and 20 million test results. Water utilities nationwide detected more than 300 pollutants between 2004 and 2009. More than half of these chemicals are unregulated, legal in any amount. Despite this widespread contamination, the federal government invests few resources to protecting rivers, reservoirs, and groundwater from pollution in the first place. The information below summarizes test results for this utility and lists potential health concerns.
Contaminants Exceeding Health Guidelines
Other Detected Contaminants
Testing History-Tested      -Detected      -Over Health Guidelines      -Over Legal Limit*
|NitrateNitrate enters drinking water sources from fertilizer runoff, leaching septic tanks, and erosion of natural deposits; it is also emitted by chemical, petrochemical and metal-finishing industries.||0.4 ppm|
|NOTE: Each dot in the above graph represents one month.|
* Water utilities are noted as exceeding the legal limit if any test is above the maximum contaminant level (MCL). Most MCLs are based on annual averages so exceeding the MCL for one test does not necessarily indicate that the system is out of compliance.
