Water in Washington and Arlington County was confirmed safe to drink again on July 4, just one day after precautionary boil water advisories were issued because of increased algal blooms.

The District of Columbia Water and Sewer Authority (DC Water) announced in a press release that all DC Water customers who had been under the precautionary boil water advisory may now use tap water for all purposes.
