7 Rhode Island Ave Ne, Washington, Dc 20018
Dccr proposes to drill one monitoring well nebbc-71 located at 7 rhode island avenue ne. The boring will be 8 inches diameter and 165 feet bgs, drilled by mud rotary methods. A monitoring well will be installed at 12 feet bgs and a vibrating wire piezometer installed at 1 feet bgs. All drilling generated waste will be drummed, tested and shipped offsite for disposal. In the event the well is not completed within 1 day, the well shall be covered protected from surface water drainage, and the vertical migration of contaminants and other materials through the well casing and well annulus. A locking well cap will be installed and the rig parked over the excavation to prohibit vandalism. No drilling spoils or excavated soils will be used as backfill. See idw management plan and attached schematics for additional information.
