Mine Drainage and Water Quality Research
The USGS Pennsylvania Water Science Center conducts research on geochemical and hydrological processes that control water quality, including the sources, transport, and attenuation of metals and nutrients in undisturbed and mining-impacted watersheds and aquifers.
Results apply to scientific and regulatory programs for the prevention and remediation of aquatic contamination.
Recoding of AMDTreat Phase 2: Integration of PHREEQ-N-AMDTreat water-quality prediction tools with recoded AMDTreat cost-analysis software
Determination and prediction of micro scale rare earth element geochemical associations in mine drainage treatment wastes
Pollutant co-attenuation via in-stream interactions between mine drainage and municipal wastewater
Mine drainage precipitates attenuate and conceal wastewater-derived phosphate pollution in stream water
Interactive PHREEQ-N-AMDTreat water-quality modeling tools to evaluate performance and design of treatment systems for acid mine drainage
Batch extraction method to estimate total dissolved solids (TDS) release from coal refuse and overburden
Hydrologic characteristics and water quality of headwater streams and wetlands at the Allegheny Portage Railroad National Historic Site, Summit area, Blair and Cambria Counties, Pennsylvania, 2014–16
Hydrological and geophysical investigation of streamflow losses and restoration strategies in an abandoned mine lands setting
Enhanced Al and Zn removal from coal-mine drainage during rapid oxidation and precipitation of Fe oxides at near-neutral pH
Acid mine drainage
Monitoring, field experiments, and geochemical modeling of Fe(II) oxidation kinetics in a stream dominated by net-alkaline coal-mine drainage, Pennsylvania, USA
Temporal geochemical variations in above- and below-drainage coal mine discharge
AMDTreat 5.0+ with PHREEQC titration module to compute caustic chemical quantity, effluent quality, and sludge volume
Interactive PHREEQ-N-AMDTreat+REYs water-quality modeling tools to evaluate potential attenuation of rare-earth elements and associated dissolved constituents by aqueous-solid equilibrium processes (software download)
PHREEQ-N-AMDTreat
USGS developed, in cooperation with the Office of Surface Mining Reclamation and Enforcement, “user-friendly” aqueous geochemical modeling tools to simulate changes in water quality during passive and active treatment of acid mine drainage.
