Water program

Downstream Strategies catalogs current conditions, links policy and management options with scientific data, and writes detailed plans. We also perform economic and policy analyses, provide expert testimony and litigation support, and conduct field monitoring. We arm our clients with the technical expertise needed to improve and protect water resources.

The Benefits of Acid Mine Drainage Remediation on the North Branch Potomac River (2010)

After decades of impairment, a successful acid mine drainage (AMD) treatment program initiated by innovative staff at Maryland state agencies has transformed the North Branch Potomac River into a popular recreational river and a driver of local economic development. This study calculates the local economic benefits generated in these Maryland counties stemming from AMD remediation on the North Branch, so that policy makers can make informed decisions about future funding to ensure that this remediation continues. These benefits are calculated from a survey of North Branch anglers and boaters.

Plants Not Pipes: Promoting Green Infrastructure and its Side Benefits in Region VI (2010)


Green infrastructure refers to stormwater management techniques that infiltrate, evapotranspire, and capture and reuse runoff. These techniques include green roofs, rain barrels, permeable pavement, and many others. In addition to reducing the volume and pollution levels of stormwater runoff, green infrastructure provides many side benefits ranging from reduced maintenance and water utility costs to improved aesthetics and air quality. This report is part of a broader project to introduce green infrastructure to communities within West Virginia’s Region VI Planning and Development Council’s region and to provide tools to encourage more widespread use of the techniques.

Field monitoring

  • Streams and water wells
  • Chemical, physical, and biological monitoring, including fish and benthic macroinvertebrates
  • Surface and underground coal mines
  • Natural gas drilling, including Marcellus Shale

Marcellus Shale Water Monitoring

DS employee monitoring well water

As more Marcellus Shale gas wells are fractured across West Virginia and Pennsylvania, nearby property owners may have concern about the quality of drinking water or nearby streams. Water monitoring can document baseline water quality and detect potential changes. Downstream Strategies offers technical staff to conduct a variety of water monitoring and related services for property owners near gas wells. All water samples are analyzed by a certified laboratory to ensure results are accurate and defensible.

The Benefits of Acid Mine Drainage Remediation on the North Branch Potomac River


After decades of impairment, a successful program initiated by innovative staff at Maryland state agencies has transformed the North Branch Potomac River into a popular recreational river and a driver of local economic development. This remarkable improvement in water quality is the direct result of the installation of eight dosers since 1992, which add alkaline material to the river and its tributaries to treat acid mine drainage from abandoned coal mines. This study calculates the local economic benefits generated in these Maryland counties stemming from acid mine drainage remediation on the North Branch, so that policy makers can make informed decisions about future funding to ensure that this remediation continues. These benefits are calculated from a survey of North Branch anglers and boaters and include three types: local spending, the economic impacts of that spending, and the willingness-to-pay even more for recreational experiences.
