The radon mitigation database keeps track of when mitigation has occurred at locations and of the levels of radiation reduction achieved. The data derived in the State of Pennsylvania is published and searchable online on the www.pa.gov website. This data will be updated annually for the prior calendar year in the first Quarter of the following year.

“e-Manifest” is Pennsylvania’s record of tracking hazardous waste shipments electronically and is maintained by the PA DEP. The records are submitted to the EPA’s e-Manifest system modernizing the nation's cradle-to-grave hazardous waste tracking process while saving valuable time, resources, and dollars for industry and states. EPA launched e-Manifest on June 30, 2018.
This dataset includes the eManifest Generator and Disposal Sites both collected and stored electronically in the National Waste Management RCRA (Resource, Conservation and Recovery Act) Information System since 2018. The PADEP Waste Management Program has been working with their national counterparts in receiving and integrating this data with its state eManifest system and eFACTS, its enterprise application system. Discussions of major revisions to integrate these internal systems are underway, which could temporarily suspend the receipt of this information for an undetermined period of time. Refresh frequency is anticipated to occur quarterly, but may be delayed until the potential interruption in this service is resumed.
The Department of Homeland Security (DHS) maintains a list of Chemicals of Interest (COI). In cooperation with DHS this website excludes waste lines from the manifest, including the quantity, that contain COI. This website also excludes the manifest's shipped and received dates for manifests containing COI. These exclusions should be taken into account when using this data.

EPA's Emissions Inventory System (EIS) contains information about sources that emit criteria air pollutants (CAPs) and hazardous air pollutants (HAPs). This data contains the facility information for Pennsylvania counties. EPA collects information about emission sources and releases an updated version of the NEI database every three years. The data made available in the NEI are used for air dispersion modeling, regional strategy development, setting regulations, air toxins risk assessment, and tracking trends in emissions over time. The data derived in the State of Pennsylvania is published and searchable online on the www.pa.gov website. This data will be updated annually for the prior calendar year in the first Quarter of the following year.

Safe Drinking Water Information System (SDWIS) is EPA’s national database that manages and collects public water system information from states, including reports of drinking water standard violations, reporting and monitoring violations, and other basic information. The data derived in the State of Pennsylvania is published and searchable online on the www.pa.gov website. This set contains the Water System Facility data, which will be updated annually for the prior calendar year in the first Quarter of the following year.

Pennsylvania collects and manages public drinking water system information in the Pennsylvania Drinking Water Information System (PADWIS).

The data includes water system inventory information, drinking water sample results for testing required by the regulations and violations of PA Safe Drinking Water Regulations, pertaining to monitoring/reporting requirements, MCL exceedances, and treatment techniques.
Much of this data is searchable via the www.drinkingwater.state.pa.us website. This set contains drinking water sample results reported on behalf of Pennsylvania’s regulated public water supplies.
The data is updated quarterly.

This dataset contains summary information on the status of authorizations under Department of Environmental Protection (DEP) Permit Decision Guarantee Policy that were outstanding in July 2017. The data maintains July 2017 as a baseline and shows DEP’s progress to issue or deny that specific group of authorizations
