Estrogen equivalents of surface water in Pennsylvania, 2012-2017
Description
The data were gathered as part of a long-term, seasonal assessment of estrogenicity in selected locations within Pennsylvania from 2012-2017. Data were collected over this time frame to determine seasonal and annual changes in surface water estrogenicity.Estrogen is reported as estrogen equivalents (EEQ) as determined by a bioluminescent yeast estrogen screen. A total of 193 grab water samples were collected during this time of which 41% had EEQ above the limit of detection. The maximum estrogen equivalents (EEQ) measured was 5.44 ng EEQ/ L, while the median concentration was 0.44 ng/L. POCIS samplers were deployed at a number of sites to determine time-weighted estrogenicity between 2014 and 2017. A total of 150 POCIS samples were deployed over this time of which 77% had EEQ above the limit of detection.. The maximum estrogen equivalents (EEQ) measured was 12 ng EEQ/ POCIS.
