Environmental remediation RFPs and government contracts

An environmental remediation RFP (request for proposals) is a notice in which a government agency asks companies to clean up contaminated soil, water and sites, with a price and a proposal sent by a deadline. Federal agencies publish them on SAM.gov as solicitations, combined synopsis/solicitations or requests for quotes; presolicitations and sources sought notices announce them earlier.

9 on Nov 11, 2026, from 8 federal agencies in 12 states. 14 of the open bids are set aside for small businesses. The list is updated every day from SAM.gov.

Bids for this service mostly use 562910 (Remediation Services), 562211 (Hazardous Waste Treatment and Disposal), 237990 (Other Heavy and Civil Engineering Construction) and 541620 (Environmental Consulting Services). Check the NAICS code in each notice: it decides the size standard for small-business set-asides.

The middle half of the 8 recent awards with a published amount was between $13K and $4.3M (median $423.8K), from SAM.gov award notices. The award amount is the value in the notice, often including options.
