Wastewater Discharge Data by Water Year

Below are tabular datasets of wastewater data for the entire state for years 2009-2018. Wastewater Release Sites (National Pollution Discharge Elimination System) were retrieved from the ODEQ database. Flow data and water-quality parameters for sites in Oklahoma were retrieved from the EPA (Permit Compliance System/Integrated Compliance Information System) database. Each annual table includes data for each water year (October through September).
