The Office of Sustainability and Environmental Resources (OSER) conducts three (3) types of water quality monitoring activities throughout the year to fulfill permit requirements. These monitoring projects evaluate and analyze the real-time chemical, physical, and biological aspects of a stream, as well as the overall 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 aims to use these surveys in order to identify potential opportunities for our Watershed Restoration Capital Improvement Projects.
OSER is currently in their second year of the third round of county-wide stream surveys. Countywide Monitoring reports and fact sheets can be found on our Publications and Resources under the Water Quality Monitoring Tab.
When Capital Improvement Projects have been funded, OSER is required to monitor restoration project goals by capturing existing conditions, pre-construction (typically a period of two (2) years), and comparing post-construction data for five (5) years after project completion. The goal is to see an improvement within the project limits based on the results of the comparison. 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.

Concentrated Long-Term Monitoring
In 1999, yearly water quality sampling was initiated in Urbana to establish a baseline, pre-existing conditions, and monitor development as it progressed. This yearly monitoring is conducted during storm events, and is a regulatory requirement directed by MDE. Until 2017, the existing conditions at Peter Pan Run were documented and evaluated during the development process in Urbana, at which point fifteen (15) stormwater management ponds were identified for a retrofit effort within the Peter Pan Drainage area in order to better treat stormwater runoff and improve stream health. Thereafter, the yearly water quality sampling assessed and monitored the impacts of a large scale restoration project on a watershed and compared the efficacy of BMP treatments. The 2017 Peter Pan Run Report is the last report that establishes pre-existing conditions and identifies the need for stormwater management retrofit efforts. The 2019 Peter Pan report is the most recent report since 2017 that contains the comparison data between pre- and post-retrofit impacts on watershed health. Both reports are linked in the table below.
