PL PollutionLookup.com EPA-backed pollution lookup
Unified pollution lookup

See the contamination story around a place, not just one dataset.

One search surface for Superfund cleanup sites, TRI chemical releases, and EPA enforcement signals.

Address autocomplete routes place searches into the right county page. Facility and chemical terms still resolve through the site search stack when they are not place queries.

Data sources

The homepage is shaped around the three EPA systems in the brief.

Each source answers a different user question, and the county page is where they finally sit side by side.

Superfund

Superfund layer

Cleanup status, contaminants, and milestone timelines for the most serious legacy contamination sites.

Mapped to site detail pages and county summaries. Official source
TRI

TRI layer

Facility-level toxic release reporting across air, water, and land pathways, rolled into chemical and facility pages.

The clearest answer to 'what is being released near me?' Official source
ECHO

ECHO layer

Inspection, enforcement, and significant noncompliance signals that make raw release tables more actionable.

The legal and due-diligence layer of the product. Official source
County pages

The county pages are the commercial core.

They turn broad search intent into a specific local answer: cleanup sites, worst polluters, chemicals released, and current violation pressure.
