The U.S. Geological Survey requires a contractor to properly abandon a monitoring well in Maryland where bentonite has bridged at a casing reduction transition. The work must follow procedures from the Maryland Department of the Environment and Talbot County Health Department, with a 30-day performance period plus time for approvals and reporting. The contract is a firm, fixed-price, small business set-aside, awarded on a lowest-price technically acceptable basis. The location for performance is within the Maryland-Delaware-Washington, D.C. Water Science Center area. No budget amount is specified.
