TL;DR: Human health risk assessments indicate that concentrations in groundwater, which is used as a drinking water source, appear to pose minimal risk, and risk calculations conducted on the wastewater effluent suggest that the risk posed by PPCPs that persisted in the effluent are medium to high to aquatic organisms.

TL;DR: In this article, the authors examine hydrologic and biogeochemical responses of managed catchments regarding the degree of stochastic, nonlinear filtering of hydro-climatic and anthropogenic drivers.

TL;DR: Maximum observed hormone concentrations were well above the lowest observable effect concentrations for these hormones; however, complexities at the field scale make it difficult to directly relate hormone concentration and impacts on fish.

TL;DR: Water samples were collected from 26 households with private wells in the West Branch of the Susquehanna River basin in central Pennsylvania in winter 2017 and a simple, physicochemical-based modeling approach was used to predict pharmaceutical transport from septic absorption field to groundwater.
