Report Environmental Concern

This is a photo of polluted runoff coming from an outfall pipe.
Polluted runoff is seen when it discharges from
outfall pipes.

Citizen reports of environmental problems are a great complement to regular monitoring programs. You can provide surveillance at a level beyond that of the monitoring staff. Citizens often can provide immediate local information that increases the chance of eliminating illicit connections to pipes in the storm drain system.

See below to learn the difference between and emergency and a concern.


An environmental emergency poses an immediate threat to public health as well as the environment. Examples of emergencies include:

  • Fish kills
  • Chemical spills
  • Sewage overflows

Call the Maryland Department of the Environment Emergency Response Division at 1-866-633-4686 if you observe a chemical spill or fish kill. This is serviced 24 hours a day.

Report sewage discharges to Baltimore County Department of Public Works by calling 410-887-7415. This is serviced 24 hours a day.


A concern is a problem that could have negative impacts on the environment, such as trash dumping or discharging wash water to a storm drain. To learn more about stream pollution visit these other Baltimore County web pages about monitoring runoff from outfalls, chemical monitoring and severe stream erosion.


To report a concern, complete the online form below or call 410-887-5683 weekdays between 7:30 a.m. and 3:30 p.m. Pictures can be emailed to
