    • E. coli dataset at from the Outfall of the Nogales International Wastewater Treatment Plant, geographic NAD83 (Water Years 2009–2015)

    Metadata Updated: July 6, 2024

    This dataset contains E. coli data collected at the Outfall of the Nogales International Wastewater Treatment Plant (NIWTP; SC6, 312724110580501) by U.S. International Boundary and Water Commission (IBWC) personnel. The IBWC collects discrete samples at the Outfall of the NIWTP daily or weekly by dipping a 100 mL sterilized IDEXX bottle in the centroid of flow. Samples are kept chilled and shipped to Turner Laboratories Inc. or Legend Technical Services Inc. Both laboratories use standard method 9223B for E. coli analysis, which uses the Colilert™-24 (Colilert) and Quanti-Tray®/2000 (Quanti-Tray) system. The holding time specified for wastewater is 30 hours. The dataset is a compilation of multiple paper records. E.coli concentrations reported as 0 most probable number (MPN) per100 mL were qualified as less than the 1 MPN/100mL specified by the Colilert test. The datasest includes E. coli concentration data for the period of June 01, 2009 to March 31, 2015.
