Some land has a history. We deal with it.

PuritySites is an environmental remediation firm for brownfields, contaminated sites, and toxic waste. We run the whole arc — Phase I records review through active cleanup to regulatory closure — and we've done it on EPA grant funding as well as private contracts.

Permit applications, closure reports, institutional controls, and deed restrictions. We handle the paper so the cleanup actually counts.

Process

Contamination to closure in four moves

1Assess

Phase I/II work identifies and quantifies what's in the ground.

2Plan

Remediation action plan with cost estimates and regulator sign-off.

3Clean

Active remediation with the most effective technology for the site.

4Restore

Restoration, monitoring, and a clean bill of health at closure.

Funding

Cleanups get paid for four ways

Remediation projects rarely run on one checkbook. We work across all of these, often on the same site.

EPA Brownfields grants

Assessment, cleanup, and revolving loan fund grants under the EPA Brownfields Program.

State programs

Voluntary cleanup programs, brownfield tax incentives, and environmental insurance.

Private contracts

Direct engagements with property owners, developers, and municipalities.

Noosphere Foundation

Partnership funding for environmental restoration through the CC ecosystem's 501(c)(3).
