Gilman, Colorado: Toxic Town


By Michael J. Lynch, University of South Florida, FL


Gilman, Colorado is an example of a toxic town (see entry on toxic towns in this dictionary). Originally founded in the 1880s as a silver mining location, Gilman later became the site of lead and zinc mining. Pollutants from the mining process are widespread in the area. The site covers 69 acres.

The site was officially abandoned under order from the US EPA in 1984 due to extensive groundwater pollution. Gilman is now a ghost town existing entirely on what is now private property. In 1990, the US EPA entered into an agreement with the State of Colorado to remediate the site. For further discussion of the outcomes of this remediation see the US EPA record of decision (Gilman decision). Click this link for the most recent EPA assessments (Gilman EPA Assessment).
