The Arlington County Police Department will participate in the D.C. region’s second annual Litter Enforcement Month in April.

Police will actively enforce litter and illegal dumping laws during the month. The goal, according to an ACPD press release, is to “raise awareness of litter, illegal dumping and related crimes; the laws associated with them, and their social and environmental effects on our communities, our economy and the Potomac River.”

Litter Enforcement Month coincides with the 24th annual Potomac River Watershed Cleanup.

“Preventing trash pollution in the Potomac starts by enforcing litter and illegal dumping laws in our neighborhoods,” Arlington police Sergeant John Ravinskas said in a statement.
