EPA has warned drinking water in the nation’s capitol may contain dangerous levels of toxic chemicals, including lead, cadmium, mercury and other contaminants.
According to a statement issued Thursday, EPA officials have determined that water samples taken in December 2015 and January 2016 contained levels of lead and cadmia levels of 50 ppb and 50 ppg.
The agency has also identified a potential high level of mercury contamination in some samples.
In its statement, EPA said the tests also indicated elevated levels of cadmias and lead.EPA is also investigating possible health impacts from the contamination of water samples, which were taken between January 1 and April 14, 2016.
The agency said the levels found in drinking water samples ranged from levels of 1.7 to 8.3 ppb per liter, with a median value of 6.3.
EPA is investigating the contamination to determine whether it is linked to any human health risks.
The statement noted that while the levels of contaminants detected in the samples were in the range of permissible levels in drinking-water standards, the EPA does not currently have a level that would trigger a “significant public health concern.”
The EPA’s Office of Inspector General, a division within the agency’s Office for Civil Rights, has launched an investigation into the incident.
