An analysis of 7,158 houses that were directly inspected through test pits by the DCWASA, reported to the U.S.
EPA, consultation with the DC Department of Health, and its own contingency plans, in 2003 the DCWASA implemented plans for families living in homes with lead lines or testing above the LAL:
* The board of directors of the DCWASA decided to adopt a voluntarily accelerated program to replace the public segment of all lead service lines in the District of Columbia, exceeding requirements of the LCR (U.S.
* The DCWASA offered free water testing to any customer in the distribution area who requested it.
Beginning in August 2004, the DCWASA conducted an Optimal Corrosion Control Treatment (OCCT) study, as required by the LCR (U.S.
From the fall of 2003, the DCWASA embarked on a massive program of replacing lead service lines, as required by the LCR (U.S.
This special program was funded by the DCWASA at a total cost of $1 million.
A subset of 177 houses with water lead levels of > 300 ppb was identified by the DCWASA through its sampling program, and the residents were invited to participate in the lead-screening program.
As Hemphill explains it, the EPA then demanded that DCWASA explain whether it had failed to adequately monitor for lead or to adequately alert the public and the EPA about the elevated levels.
In July, DCWASA accelerated its timetable for replacing its lead service lines, promising to complete the job by 2010 (under EPA regulations, water systems need replace only a small percentage of public service lines per year and may approve lines using lead testing in lieu of actual pipe replacement).
In addition, DCWASA has completed coating, chlorination and testing along the entire length of the main.
* DCWASA will install 2,050 feet of 12-, 8-, and 6-inch ductile iron water mains, 20 valves, upgrade five hydrants and replace 10 sewer connections; and
