PHILADELPHIA (WPVI) — The Penn Environment and Research Policy Center has released a new report spotlighting sewage overflow in Philadelphia.

The group released their findings at the Fairmount Water Works Monday morning.

Their report includes a new interactive online map showing the areas with the largest sewage discharges.

The hope is that the information is useful to Philadelphians who want to safely fish, boat, and take park in recreational activities in the city’s rivers.
