The Ground Truth is Warren Nelson's newsletter on contaminated soil remediation: what the evidence actually shows, where treatment technologies genuinely differ, and what it takes to reach a permanent, verified outcome. It is written for site owners, consultants and public-sector teams who make decisions about contaminated land.
Each edition takes one decision that remediation projects actually face and examines it against project evidence: treatment selection, verification sampling, regulatory criteria, mobile versus fixed infrastructure, and the difference between managing contamination and destroying it. The newsletter draws on Nelson's project record, including the Tioga pipeline spill cleanup in North Dakota, the Honolulu brownfield remediation, and thermal treatment work across Alberta.
The name reflects the editorial standard. Claims are tied to documented projects, published regulatory criteria and named sources. Where the evidence is still developing, as with PFAS destruction pilot work, the edition says so plainly.
LinkedIn is where subscribers receive each new edition, and that channel continues. Publishing selected editions on this site gives them a permanent address that can be cited, shared with colleagues who are not on LinkedIn, and connected to the project records, maps and tools the edition discusses.
Website editions carry the same core editorial message as the LinkedIn original, with supporting links to Nelson's project records, The Hub contamination maps and the Strategy Navigator where they add useful context.
The Ground Truth is published on LinkedIn and read by a growing subscriber base of remediation professionals. Subscribing on LinkedIn delivers each new edition to your LinkedIn feed and inbox when it publishes. New editions are announced from Warren Nelson's LinkedIn profile and the Nelson Environmental Remediation company page.
