Arlington County officials are warning residents to stay out of Four Mile Run Stream because it has been contaminated with waste from a portable toilet for the second time in as many weeks.
The waste was dumped into a storm drain and flowed into the stream near Interstate 66 and Westover and Bon Air parks, officials said. A resident reported the spill about 8:30 this morning. [...]
Officials believe the illegal dumping is connected to a similar incident that occurred July 31. The county also had advised residents to avoid the water after that spill, but lifted the advisory Tuesday after clean-up, days of stream flow and a rainstorm helped flush away bacteria from the spill.
Park officials and Arlington fire officials are investigating.
I don't think most people realize Arlington's storm drains often flow straight into our local waterways with no treatment. Hopefully Arlington authorities can catch who's responsible -- it's our tax dollars that are paying to clean up these messes.
