Water Quality Monitoring

The Division of Energy and Environment monitors the condition of the waterways in our portion of the Chesapeake Bay Watershed. We conduct three types of water quality monitoring activities throughout the year to fulfill MS4 Permit requirements. These monitoring projects evaluate and analyze the current chemical, physical, and biological aspects of a stream, as well as the overall trends in watershed health following Maryland’s Biological Stream Survey (MBSS) protocols.  

Frederick County Stream Survey

Frederick County has conducted a county-wide study of the health of its watersheds from 2008 to present. The study focuses on analyzing the stream health of different streams within a specific watershed. Each stream is inspected and scored for a variety of parameters including the presence of stream bug species, the quality of the physical habitat, the area of streamside forest buffer, the severity of stream bank erosion, and the amount of nitrogen and phosphorus in the streams based on a grab sample. Frederick County utilizes information gathered from these surveys to identify potential restoration opportunities in the County’s Watershed Assessments.  Those opportunities are ranked and the highest cost-effective restoration projects are moved into project implementation through our Watershed Restoration Capital Improvement Projects.

The Division of Energy and Environment is currently in their fourth year of the third round of county-wide stream surveys. Visit the Frederick County Stream Survey Page to view the interactive map, the Countywide Monitoring reports, and Round Monitoring fact sheets.

Restoration Monitoring

Funded restoration projects, who ranked the highest in priority, progress into project implementation through the County’s Capital Improvement Projects (CIP).  Those restoration projects which  require monitoring of restoration project goals will receive pre-restoration monitoring to capture existing conditions (typically a period of two (2) years), and comparing post-restoration data for five (5) years after project completion. Successful projects are rated based on whether their specific goals are achieved. These monitoring efforts assist the County in not only identifying when a project may need repairs but to also improve our overall future project designs. Based on the location and the proposed project, the project goals could be aimed at improving a variety of aspects starting with hydrology and moving up a hierarchal process to include: hydraulics, geomorphology, physiochemical, and/or biology. 

Peter Pan Run: Concentrated Long-Term Monitoring Water Quality Instrument

In 1999, yearly water quality sampling was initiated in the Urbana region to establish a baseline conditions and monitor Peter Pan Run as the surrounding land area was developed. This yearly monitoring is a regulatory requirement directed by the Maryland Department of the Environment. 

The monitoring program was designed to build a long-term database (currently 1999 to 2024) of water quality and biological conditions and to assess the cumulative effects of both stormwater runoff stemming from development and the impact of restoration projects in the watershed.
