For the second time in two weeks, portable toilet waste was dumped into Four Mile Run Park, which borders the Arlandria section of Alexandria. Officials are warning residents and visitors to stay away from the contaminated water, usually a popular spot for fishing, biking and other outside recreation.

A vacuum truck was used to remove the waste, which was dumped into a storm drain and seeped out near Interstate 66 and Westover and Bon Air Parks. According to Arlington County officials, a resident reported the waste spill last Thursday around 8 a.m. after noticing an offensive odor. Since the original complaint, there have been no other reports from residents.  However, the county has complied with requests to place warning signs around the site.

Chief Fire Marshal Benjamin Barksdale is leading the Arlington County Fire Department investigation. No arrests have been made. 

Recent excessive rains have impeded restoring the stream. Immediately after the spill, hydrants were opened around the area to flush out the harmful contents and to reduce the odor, according to the Arlington County Department of Environmental Services.

After positive test results from water samples this past week, the Department of Environmental Services has decided to lift the advisory as of today. 

Anyone with information that would benefit the ongoing investigation, call 703.558.2222.
