As summer’s hottest month heats up, the country celebrates National Water Quality Month. This month is a time to educate individuals and companies about steps they can take to protect the country’s sources of fresh water.
State, federal, and local regulations govern the wastewater that companies can dump directly into water supplies. These regulations do not provide perfect protection—witness the 2014 coal ash spill into the Dan river—but they prevent companies from deliberately disposing of their waste products into the water.
The more insidious impact, however, comes from the way that people add chemicals to the water supply without even knowing it. This happens through rainwater runoff, when water from rain storms collects in storm drains, bringing with it all the chemicals on buildings and sidewalks that it has encountered along the way. These storm drains then empty into water supplies—still carrying environmental pollutants.
Cities—and the companies that are located there—generate five times more rainwater runoff than forests or fields. The rain washes pollutants like oil, antifreeze, pet waste, fertilizers, and pesticides right into the water supply. To avoid contributing to poor water quality, follow Clean Water Action’s fact sheet:
- Don’t use antibacterial soaps or cleaning products.
- Don’t put anything except water down storm drains.
- Avoid using pesticides or chemical fertilizers.
- Choose nontoxic household products whenever possible.
Sometimes water pollution is visible, like in the case of toxic algal blooms. More often, however, poor water quality is not visible to the naked eye. To make sure your office water supply is safe, check where your water comes from with the United States Environmental Protection Agency’s “Surf Your Watershed” tool, and buy a water quality testing kit. These standards from the General Services Administration provide good guidelines on making sure your water supply is safe.
