Nearly 6 million people live in the drainage area of the Potomac River which stretches 14,670 square miles across four states and the District of Columbia. 86% of these people get their drinking water from public water suppliers which use the Potomac River, its tributaries and surrounding ground water as their source water. And with an average flow before withdrawal of 7 billion gallons/day, it may be an understatement to say: it’s a big deal!
Luckily, this has not gone unnoticed. Organized in 2004, the Potomac River Basin Drinking Water Source Protection Partnership (DWSPP) has been working to better understand and address the risks that may negatively affect the quality of drinking water in the Potomac River basin. The Partnership is a voluntary association of 20 water suppliers and government agencies whose mission is the protection of their source water supplies in the basin. Some of the biggest interests of the Partnership are:
• Tracking research on low levels of emerging contaminants to determine their persistence in the environment and their potential threats to human health and the environment
• Early warning/emergency response to events and conditions which may threaten the safety of the water supply
• Urban issues such as the impact of roadway salts on drinking water sources
• Agriculture issues such as the potential contribution of pathogens. One example of this is Cryptosporidium, which may cause water-borne disease
Broad source water programs like the Partnership’s are significant because they extend beyond the treatment element and provide an invaluable multi-barrier approach to drinking water protection. With concerns like those above (and more) in both urban and rural areas, this collaborative approach should open the eyes of residents in watersheds everywhere.
So what should you do? Educate yourself on the issues the Potomac DWSPP is working on by visiting their website and be sure to take a look at specific information about special topics or workgroup activities. You may also find information like how to properly dispose of pharmaceuticals, as well as other ways you too can ensure safe drinking water for your area.
