The Pennsylvania Oil and Gas Waste Mapping Tool includes interactive visualizations that show waste generation and handling from oil and gas development in Pennsylvania as reported to the Pennsylvania Department of Environmental Protection (PADEP). Click below to view oil and gas wastewater generation by county and oil and gas wastewater handling locations and handling methods across Pennsylvania and neighboring states.

Wastewater Generated from Oil and Gas Development in Pennsylvania (1991 - 2017)
Explore wastewater generated by oil and gas development in Pennsylvania by county, by well type, and by waste type. Hover over visualizations to see annual wastewater volumes and the number of wells responsible for generating wastewater. All wastewater volumes are reported in barrels (bbl). Briefly, unconventional wells tap into unconventional source rock formations (e.g., the Marcellus shale) and employ extraction techniques such as high-volume hydraulic fracturing (e.g., fracking). Conventional wells produce from conventional formations, and may or may not use hydraulic fracturing to extract oil and gas.
Oil and Gas Wastewater Handling Locations (1995 - 2017)
Explore wastewater handling locations and handling methods for oil and gas wastewater within and beyond Pennsylvania. Wastewater produced from oil and gas wells may be stored, treated, disposed, or reused. While certain waste handling methods indicate the final end point for waste (e.g., injection disposal wells), other categories reflect an intermediary point and not the final destination for waste (e.g., storage pending disposal or reuse).
1 The database of oil and gas waste used for these visualizations was compiled by the Pennsylvania Department of Environmental Protection (PADEP). For more details visit: https://www.paoilandgasreporting.state.pa.us/publicreports/Modules/Welcome/WasteFacilityReport.aspx
2 PADEP suffered an unrecoverable data loss in 2007, explaining the limited waste generation and waste handling data available for this year.
3 While waste generation data reported to PADEP begins in 1991, spatial information is not available until 1995. As such, the waste generation visualization includes data from 1991 to 2017 and the waste handling visualizations show data from 1995 to 2017.
4 The spatial visualizations (maps) are limited to waste records that included verifiable spatial information. The bar graph visualizations include all wastewater volumes reported to PADEP, regardless of if spatial information was included.
5 Road spreading was often reported at the municipality or county level. Road spreading wastewater volumes reported at the municipal or county level are captured in the bar graph visualization, but are not shown in the mapping visualization.
6 Over time, a single waste handling location (e.g. facility or well) could be reported with multiple waste handling methods. While facilities could change over time with upgrades and new permitting, we assumed that the waste handling method was consistent across a calendar year. To address this, we visualize the facility- or well-specific waste handling method reported most frequently for each year.
For questions, comments, or to report any errors in the data or trouble with the Pennsylvania Oil and Gas Waste Mapping Tool, please ask Lee Ann Hill at: firstname.lastname@example.org. These reported data are accurate to the best of our knowledge, but there may be errors in data reporting and data compilation. We would appreciate any input if you notice any anomalies or inaccuracies to help improve this visualization. We are also eager to help you navigate and use the tool, so please reach out if we can help you these visualizations to answer any specific questions!
