Drinking Water Quality Reports

Get the Facts About Your Drinking Water

Water Quality Report

Here you can view College Station's annual drinking water quality reports, also known as the Consumer Confidence Reports. If you have ever wondered where your water comes from, or what is in your drinking water, you will find the answer to these and more questions in these documents. Public water suppliers must provide these reports to their water customers each year by July 1, as required by the 1996 amendments to the Safe Drinking Water Act (SDWA).

These reports are full of some complex language and long words (trihalomethanes?! Cryptosporidium?!). To help you understand the terms in your drinking water quality report, here are some helpful links from the Environmental Protection Agency (EPA) the American Water Works Association (AWWA), and NSF International:

Water quality is maintained in the distribution system through continuous monitoring of water pressure, temperature, disinfectant residual, and turbidity. Environmental Technicians also collect at least 91 water samples each month throughout College Station for analysis by the Brazos County Health Department. Samples are tested for Total Coliform bacteria, which are usually indicators of microbial contamination of drinking water because they are often found in association with other disease-causing organisms (though hardier than most pathogens).

College Station Utilities also maintains a chlorine disinfectant residual of at least 0.2 milligrams per liter (mg/L) throughout the water distribution system to prevent against bacteriological contamination after the water leaves the Dowling Road Pump Station.

In January 2011, the U.S. Department of Health and Human Services proposed lowering the recommended level of fluoride in drinking water to 0.7 mg/L. College Station's drinking water comes from the Carrizo-Wilcox Aquifer and, as noted in the drinking water quality reports linked above, contains approximately 0.4 mg/L fluoride already. Following this change by HHS, in September of 2011 the City of College Station discontinued adding fluoride to the drinking water. A detailed explanation of this decision to discontinue fluoridation can be found in this blog post from September 2011. More information about drinking water fluoridation, including its risks and benefits, can be found at
