This poster details a research project undertaken to analyze the impact of a wetland passive treatment system for the remediation of acid mine drainage (AMD) on downstream surface water quality and aquatic habitats. An original study done in 2000 focused upon developing a prioritization of sites for acid mine drainage remediation in the Lower Yellow Creek Watershed located in southwestern Pennsylvania. Approximately two years after the original study, a local watershed association installed a passive wetland treatment facility to restore water quality in the heavy affected drainage. The present project, undertaken eighteen years after the installation of the constructed wetland, involved a second assessment of water quality and aquatic habitat conditions downstream of the system. Various sampling techniques were employed including; rapid habitat assessment, macroinvertebrate sampling, and analytical water chemistry. Analysis of data resulting from these sampling techniques provides insight into the effectiveness and spatial patterns of impacts of the passive wetland AMD treatment system facility in Lower Yellow Creek drainage.
