According to a press release from Marylou Berg, Director of Communication, “Once again in 2016, Rockville’s drinking water met or exceeded all drinking water quality regulations set by the Environmental Protection Agency and adopted and enforced by the Maryland Department of the Environment.”
The Annual Drinking Water Quality Report will be officially released on June 30, 2017. The report details the source, treatment, distribution, safety, and quality of Rockville’s drinking water.
For testing lead and copper, tap water samples were taken from 33 addresses within the city during 2016. The testing detected lead in just two samples, at levels far below where the Environmental Protection Agency takes regulatory or remedial action. The tests also showed copper levels far below the EPA action level.
The City has a new chemical feed system at the city’s water treatment plant on the Potomac River. On March 21, 2017, the plant began full-time use of ferric chloride to coagulate and remove organic compounds from the river water, improving the quality of the city’s drinking water. If you are not aware, all drinking and bottled water can be expected to contain small amounts of some contaminants. According to the City’s website, the presence of these contaminants does not necessarily indicate that water poses a health risk. Obviously, all water comes from rivers, lakes, streams, ponds, reservoirs, springs, and wells, where it dissolves naturally occurring minerals and can pick up substances resulting from the presence of animals or from human activity.
