DECinfo Locator

DECinfo Locator is a map-based way to easily access many documents and public data pertaining to the environmental quality of specific sites in New York State. By searching for a location on this map, you will see facility icons where you can view and download water permits, water quality data, and information about clean-up activities for that location. This tool and data are maintained by the NYS Department of Environmental Conservation. Icons represent the availability of data, not necessarily the presence of contamination or other problems.

This prototype focuses on the Newburgh area (Orange County) and the Owasco Lake watershed area (Tompkins and Cayuga counties) only. Additional locations, documents and data will be added in the next version of DECinfo Locator.

Please take our short feedback survey (only 5 questions) after using the prototype so we can make improvements with the next version.

Available Functionality

Function buttons you
will see on the map

You can access documents and data by clicking on any icon you see on the map. More icons appear when you zoom in closer. There are a number of features you can use within the mapping interface. These are located in the upper right corner of the map.

  • Legend - shows the symbol for each category of facilities and locations we have available data sets/documents.
  • Layers - you can determine which category of facilities and locations you want shown on the map. You can turn each off and on by clicking the check box.
  • Near Me - you can search facilities and locations near you up to a 15 mile radius. You can access documents and data by clicking on the facility name in the category drop down list.
  • Basemap Gallery - you can change the background map view. If you zoom into a particular location, switching to the Imagery with Labels view will show more details, including land boundaries and buildings. The default is set to Streets View.
  • Search - the default setting is to search location names, street addresses and zip codes; if the map doesn't zoom into the location you typed, check that the search dropdown arrow is set to ALL.

Map terms are linked from each facility detail box, as well as described on our map terms web page.

Newburgh Area Background Information

The City of Newburgh discovered perfluorooctanesulfonic acid (PFOS) in Lake Washington and reported it to the EPA. Although all samples were below the EPA's provisional short-term health advisory that was in place at that time, New York State assisted the city in early 2016 to conduct a comprehensive site investigation in potentially affected areas. The investigation identified Stewart Air National Guard Base as the likely source of PFOS contamination in the area due to the use of PFOS-containing firefighting foam. DEC listed Stewart Air National Guard Base as a state Superfund site in August 2016 to hold the U.S. Department of Defense (DoD) responsible for full site clean-up.

The state swiftly transitioned the city to a clean, alternative drinking water supply and launched an ongoing initiative to sample private wells in the affected area. The state is funding municipal water supply connections and point of entry treatment systems (POETs) to impacted private residences in the Towns of Newburgh and New Windsor. The state also built a system to draw down water in Lake Washington-by pumping it, filtering it, and discharging clean water into the watershed-to ensure the integrity of the dam.

Why There Are So Many Map Icons

You will see many facility icons on the Newburgh area map prototype. As with any typical urban area in New York State, there are a number of municipal and industrial facilities that are permitted by DEC. Through the permitting process, DEC monitors any releases to help protect the environment and human health.

Owasco Lake Watershed Background Information

The Owasco Lake watershed is found in Tompkins and Cayuga counties. There has been an increase in warm weather occurrences of Harmful Algal Blooms (HABs) in the lake - dense blooms of blue-green algae. These blooms can produce nerve, liver and skin toxins that can harm swimmers, pets, and those who drink the water. For the first time, low but significant levels of the HAB-related toxins were detected in the treated public drinking water of both the City of Auburn and Town of Owasco in 2016. Excess nutrients, particularly phosphorous, typically cause HABs. However, the cause of this lake's HABs are not adequately understood, requiring additional studies while efforts to control nutrients and sediment pollution continue.

The New York State Departments of Health, Agriculture and Markets, State and Environmental Conservation are all working to improve the lake's water quality in close cooperation with local communities. In addition to phosphorus and pollution reduction projects, a sewer extension has recently been completed in the Town of Owasco and septic users will be transferred to sewer connections beginning in spring 2017.

As with many rural areas in New York State, you will see farms and clean-up sites on the Owasco Lake watershed area map prototype. Owasco Lake was chosen to be a case study to investigate the cause of HABs and identify best management practices. More information can be found on our HABs web page.
