Gwynns Falls Outfall Screening Blitz

Learn about water quality testing with the scientists of Blue Water Baltimore! An Outfall Screening Blitz consists of taking teams of volunteers into our local streams to sample water quality. The events take place 48 hours after a major rain event to ensure stormwater is not being sampled. Samples will be collected from streams being monitored where dry weather flow is coming from a stormwater outfall. If an outfall screening blitz is rained out, this event will transition into a stream walk. We will discuss different types of pollution, how it is entering our waterways and steps you can take to help report and prevent pollution from happening. This is a limited capacity event. Due to the limited number of spaces for this event, registration will not open until the week before the event.
