What is covered—and what still needs work

WNYAtlas publishes documented records in stages. A place appearing here does not establish exposure or harm, and a place being absent does not establish that no relevant history exists.

Geographic coverage

Six counties currently have environmental place records.

Health reporting uses the eight-county Western New York region. The environmental collection has not yet identified publishable place records in Allegany or Wyoming counties. Those zeroes describe Atlas coverage—not environmental conditions in those counties.

What kinds of places are represented

Category totals describe the page’s primary classification. A cleanup site may also carry a PFAS or radiological tag when the source record supports it.

Quality checks

What was checked in this review

  • 175 coordinates: no duplicate or out-of-region coordinate problems found.
  • 120 DEC-linked places: no differences greater than 250 meters from official DEC coordinates.
  • 55 other places: require non-DEC or manual authority checks because no matching DEC site coordinate governs them.
  • 175 histories: every place has a story and at least two sources under the current depth audit.
  • School records: unavailable DEC document directories are withheld from public links; one American Brass collection was recovered under DEC record V00314.

Next research priorities

Known gaps are kept visible.

  1. Allegany and Wyoming counties: screen official cleanup, landfill, industrial, radiological, and PFAS records before adding any place.
  2. Airborne events: add only government-defined monitoring areas or documented event records; do not invent plume boundaries.
  3. Source maintenance: recheck moved or unavailable government document collections and preserve the last review date.
  4. Visual history: add aerial comparisons only where imagery dates, rights, alignment limits, and interpretation can be explained.
