Chemistry of streams draining mined and unmined watersheds in the mountaintop mined landscape of Central Appalachia, USA

Résumé

Mountaintop removal coal mining is the predominant form of surface mining in the Appalachian Region, USA and leads to elevated levels of chemical constituents in streams draining mined watersheds. This data set contains measurements of water chemistry in the mountaintop mined landscape of Central Appalachia, USA. These data were collected to determine the accumulation and transport of mercury (Hg) and selenium (Se) across environmental compartments in mountaintop mining-impacted waters as well as the impact of mountaintop mining on the aquatic-terrestrial subsidy. Samples were collected in summer 2017 and spring/summer 2018. Data predominantly include Se, THg, and methylmercury (MeHg) in the following environmental compartments at sites impacted and unimpacted by mountaintop removal coal mining: water, sediment, biofilm, larval cranefly, adult aquatic insects and spiders. Additional water parameters that have been found to vary across a gradient of mountaintop mining impact (total organic carbon [TOC], total nitrogen [TN], sulfate [SO4 ], nitrate [NO3 ], chloride [Cl], pH, sodium [Na], potassium [K], magnesium [Mg], calcium [Ca], manganese [Mn], sulfur [S], specific conductance) were also measured. The majority of sites represented are headwater streams, although some settling ponds below valley fills are included. This data set also includes taxonomic characterization of the adult aquatic insect community as well This article is protected by copyright.
