Rosen, M.R., and Tarar, A.M., 2020, Data for Analysis of Endocrine Disrupting Compounds in Lake Mead National Recreation Area near Las Vegas, Nevada: U.S. Geological Survey data release,


This dataset presents the results of passive water sampling conducted at 2 sites in 2013 and 3 sites in 2014 in Lake Mead National Recreational Area. Polar Organic Chemical Integrative Samplers (POCIS) and Semipermeable Membrane Devices (SPMDs) were deployed in Las Vegas Bay and Overton Arm in 2013 and Las Vegas Bay, Boulder Basin, and Overton Arm in 2014. The samplers were analyzed for concentrations of polychlorinated biphenyls (PCBs), organochlorines (DDT-type compounds and their degradates), polybrominated biphenyl ethers (PBDEs), polycyclic aromatic hydrocarbons (PAHs), waste indicators (WW), and yeast estrogen screen (YES) by the U.S. Geological Survey (USGS) at the Columbia Environmental Research Center (CERC) in Columbia, Missouri.

These data were collected as part of a cooperative study with the U.S. Geological Survey (USGS), National Park Service (NPS), and the University of Nevada, Reno (UNR) to quantify the concentrations of endocrine disrupting compounds (EDCs) in Lake Mead water. The chemical results were coupled with tissue data collected from biota and stable isotope data that determined trophic position of each species and was used to understand how contaminants bioaccumulate through the food web.
