Water quality synoptic data for Dead Run, Baltimore County, MD USA

This resource includes water quality data from synoptic sampling of streams and wells in Dead Run watershed, Baltimore County, MD. The stream network was sampled from the outlet at Dead Run Franklintown (DRKR) to the headwaters (Winters Lane in DR5) every 50 m over 5 km, after approximately 10 days of no rain, 2 to 3 times per year from 2014 - 2017. In addition, DR5 headwaters were sampled every 50 m over 1 km approximately monthly from 2017 - 2020. A network of 35 point piezometers in the DR5 subwatershed were also sampled 2-3 times per year from 2017 - 2020. Stream and well samples were analyzed for chloride, fluoride, nitrate-nitrogen and sulfate on a Dionex ion chromatography system. A subset of samples was also analyzed for d18O and d2H on a Picarro 2120-i water isotope analyzer. Three of the synoptic sampling sites are co-located with USGS stream gaging stations 01589315 (DR4), 01589312 (DR5), and 01589330 (DRKR).
