If you are interested in finding out information about ongoing investigations involving petroleum contamination of ground water in Baltimore County, view the Maryland Department of the Environment's Oil Control Program Remediation Sites.

Baltimore County is no longer processing new claims for home well water contamination alleged to be caused by road salt application. The County began to process these claims in mid-2014, although it never acknowledged liability nor has there ever been a finding by any appellate court in Maryland that a county would be liable for any damages, assuming they could even be proven. Homeowners who require help or advice with this matter are encouraged to contact and work with a well drilling or water treatment company.
