The US Environmental Protection Agency recently awarded Somerville $300,000 for the city’s Brownfield Cleanup Revolving Loan Fund. Together with $400,000 previously awarded by the EPA, the city now has $700,000 available for the program, which provides grants and low-cost loans for the assessment and cleanup of sites where potential contamination poses a hurdle to redevelopment. Through previous state and federal awards, the program has helped pay for the cleanup of such properties as Maxwell’s Green on Lowell Street and the former Kiley Barrel site in Union Square. The state Department of Environmental Protection has identified 542 known brownfield sites in Somerville, 118 of which have not yet been thoroughly assessed or mitigated.
