Delaware Facility Air Emissions Inventory for Major Pollutants

Annual emissions inventory of eight pollutants, including carbon monoxide, lead, and fine particulate matter, submitted by large facilities in Delaware. The dataset includes Facility Name, Address, and pollutant-specific columns like VOC (tons) and SO2 (tons), with a Year column indicating temporal coverage. Data is provided by data.delaware.gov and was last updated on 2026-05-07.

Use Cases

• Analyze trends in pollutant emissions like SO2 (tons) and NOx (tons) over time using the Year column.
• Map pollution sources by geolocating facilities using City, Zip, and Address columns.
• Identify facilities with the highest emissions of specific pollutants like PM2.5 (tons) or Lead (lbs).
• Cross-reference facility-level emissions data with Facility Description and Notes for compliance or impact studies.

Strengths

• Covers eight specific pollutants with dedicated columns, including VOC, SO2, PM2.5, and Lead.
• Includes contextual facility information via Facility Description, Address, and Notes columns.
• Provides a clear reporting threshold, with emissions values of 0.0001 or less reported as 0.0001.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata is limited; actual data quality and completeness of blank cells require manual inspection after download.
