Dataset includes continuous discharge at the USGS (Station ID: 05485605) Fourmile Creek near Ankeny, IA DS1 gage site (http://waterdata.usgs.gov/usa/nwis/uv?site_no=05485605) as well as daily precipitation and water level data in select groundwater piezometers recorded in 10 minute intervals during the period Oct 1, 2013 to November 30 2013. Latitude and longitude data are provided for groundwater piezometer locations. This data release supports the following publication: Hubbard, L.E., S.H. Keefe, D.W. Kolpin, L.B. Barber, J.W. Duris, K.J. Hutchinson, and P.M. Bradley. Hydrologic Impact of Wastewater Contribution to Shallow Groundwater: Before and After Wastewater Discharge Cessation. Environmental Science: Water...

The Ankeny, Iowa wastewater treatment facility (WWTF) was decommissioned in November 2013 providing a unique opportunity to characterize the impacts of WWTF discharge on water quality at the surface-water/groundwater interface in a shallow, unconfined alluvial aquifer. The Ankeny WWTF discharged treated effluent for nearly forty years into Fourmile Creek, located in Ankeny, Iowa. Dataset includes site information (Table 1), analytical methods (Table 2), piezometer water level elevations (Table 3), trace and major element concentrations collected from 2011 to 2013 before the WWTF shutdown (Table 4), and trace and major element concentration collected from 2013 to 2014 after the WWTF shutdown (Table 5).

The USGS conducted a combined wastewater facility pre/post-closure groundwater assessment adjacent to an effluent-impacted reach of Fourmile Creek, Ankeny, Iowa, USA. This data release includes pharmaceutical concentration data for Fourmile Creek determined by enzyme-linked immunosorbent assay (ELISA) and HPLC-MS/MS during the period October 2012 to October 2014, along with associated HPLC-MS/MS analyte and method performance information.
