"Looking Below the Surface" (the macroinvertebrate story map) is designed to inform and educate the public about PA DEP's benthic macroinvertebrate dataset. Not all streams and rivers are created equal, so DEP has developed unique macroinvertebrate collection methods for various stream types. DEP uses these differing methods to get a picture of water quality and ecosystem integrity. This story map touches on why benthic macroinvertebrates are so important and how they are used to measure water quality.
Macroinvertebrates are used throughout the world as indicators of water quality. Macroinvertebrate community assessments are efficient and powerful because they offer the ability to assess short-term and long-term, cumulative effects of many ecosystem stressors, including both chemical and physical factors. To address the complexities of different types of streams and the macroinvertebrate communities that may prefer certain physical or chemical features, DEP has created three unique macroinvertebrate collection methods. This app will allow you to view and download macroinvertebrate and associated data collected across the state. These data can be exported into several file types including gif, jpg, pdf, png, xlsx, and csv.
Learn about adverse human impacts on the East Coast's longest river and its tributaries and follow the progress of the Department of Environmental Protection's (DEP's) efforts to tackle them on a new interactive, multimedia website called the Susquehanna River Story. The Susquehanna River Story website uses GIS maps, videos, charts, and photos to show where mining, agriculture, stormwater, and dams have impaired macroinvertebrate, fish, and plant life, as well as DEP's progress in addressing these impairments. DEP research on smallmouth bass is also shared. Site visitors can see which streams have been impaired by farming activities as well as samples of agricultural best management practices that have been implemented to repair impacts and which streams have been impaired by acid mine drainage and locations of successful treatment projects.
The Pennsylvania Department of Environmental Protection (DEP) has published its 2016 Oil and Gas Annual Report in an interactive, electronic format to improve public access to well information. It's the first time the report has been published electronically. It is built on the ESRI platform, data are geolocated in GIS maps and real-time data is displayed, drawing from DEP's daily electronic compliance tracking system updates. The report presents 2016 data on permit activity, inspections, operator compliance, and enforcements for conventional and unconventional wells.
Municipalities and other entities such as universities and prisons that meet certain standards must obtain NPDES permit coverage for discharges of stormwater from their municipal separate storm sewer systems (MS4s). This new web mapping application allows the user to search for the municipality and see the urban area report, as well as the impaired streams.
This interactive website has been designed to facilitate filling out forms for the PA Nutrient Credit Trading Program. Use it to identify surface waters and their basin, Chapter 93 water quality uses, and impairments (section 5.D. on the certification request form, sections 3 and 6 on the registration request form).
eMapPA is a GIS based website and mapping tool that focusses on the display of environmentally relevant data to Commonwealth Agencies, contractors and the public. In addition to DEP-permitted facilities, there are over 50 map layers relating to administrative and political boundaries, culture and demographics, geology, mining, streams and water resources, and transportation networks. Tools for navigating, querying, identifying, extracting, buffering, and address matching are available for GIS analysis. All of the tools and their uses are fully explained in the Help option on the menu bar. For security reasons, information regarding Dams, Explosive Storage Locations, Public Water Supplies, and certain Water Pollution Control, Water Resource, and Radiation Facilities are not displayed on eMapPA. Permit information, inspections, and other data related to these facilities can be obtained by contacting the appropriate DEP Office.
eMapPA enables the userto identify sensitive data and non-sensitive data attributes located near aproposed project without showing the water source locations or coordinates. Also, eMapPA can assist permittees/applicants who are required to develop DownStream Notification Lists. To obtain sensitive and non-sensitive data, click on these
This interactive website shows the location of both conventional and unconventional oil and gas wells, including producing and non-producing wells, based on information from operator submitted reports. The user can request this data set to display information based on the permit number, combinations of operator that submitted the report, the county in which the well is located or the municipality (also known as Minor Civil Division or MCD) in which the well is located. The user also has the ability to use map functionality to locate a specific address, county, latitude and longitude, municipality or zip code. Please note that only wells which have locational information and are located within the boundaries of Pennsylvania will be available.

DEP Oil and Gas Well Mapping Application
This interactive web mapping application shows the location of impaired and attaining streams in Pennsylvania, which corresponds to the 2016 Integrated Water Quality Monitoring and Assessment Report. In addition, it will allow the user to see the impairment sources and causes, the category, the date listed, TMDL information, the stream names, and much more! It also allows you to print or export the information into a pdf. The user can search data based on stream name and assessment ID. The user also has the ability to use map functionality to locate a specific address, county, latitude and longitude, municipality or zip code.
Oil and Gas development in Pennsylvania has been ongoing for over 150 years. Regulatory standards for the industry have evolved significantly during this time period as a function of both advances in technology and a more intense focus on environmental protection. Materials and techniques historically used for well plugging are inadequate by today's standards. Additionally, because oil and gas development had been taking place for nearly a century prior to permitting requirements enacted in 1955, it is estimated that somewhere between 100,000 and 560,000 wells are yet to be accounted for. This story map overlays a historical oil and gas legacy development map (1930-1960s) over Allegheny County along with the Department of Environmental Protection known well inventory.
The Pennsylvania Water Quality Network (WQN) is a statewide, fixed station water quality sampling system operated by Department of Environmental Protection's (DEP) Bureau of Clean Water (BCW). It is designed to assess both the quality of Pennsylvania's surface waters and the effectiveness of the water quality management program. This new web mapping application allows the user to search for WQN information by stream, by station ID and location, and it shows the location and information about reference stations, stormwater sediment stations, standard stations and macroinvertebrate stations.
DEP launched a web mapping application for the 2016 Integrated Report that consisted of Category 5 priority waters. This map includes waters proposed for restoration alternatives and high priority impaired waters requiring a TMDL. This app will allow you to locate these waters and information regarding the watershed and reason why it was listed as either a high priority for TMDL development or restoration alternative (5alt). This application only includes the sources and causes of impairment addressed with the TMDL or alternative plan and other sources and causes of impairment may be linked to these waters and will be addressed later.
The Pennsylvania Activity and Use Limitation (PA AUL) Registry website provides the public with information on properties within Pennsylvania that have some form of use restriction or ongoing obligation associated with a remediation. The Uniform Environmental Covenants Act (UECA) requires DEP to maintain a registry of properties with environmental covenants. The PA AUL Registry meets this requirement by including properties with environmental covenants, deed restrictions, post remediation care plans or any other AUL document. Searches for properties with AULs can be performed using the map on the website or by searches on address, zip code, county or other criteria. Once a property of interest has been located it is possible to view any AUL documents that have been associated with that property.

There are known contaminant plumes affecting groundwater at various locations in Williamsport. Within these areas, if a well is to be allowed, additional sampling requirements are necessary to insure contaminated groundwater would not be used. To see if the proposed well is located in a plume, use this interactive mapping application to enter the latitude and longitude of the well. If the well resides in a contaminated location, a list of contaminants of concern (COC) and additional required sample parameters will be displayed.
