11 borings and 2 auger probes will be advanced using 3. 25 inch hollow stem augers to create a 6 inch annulus. 3 test pits will be advanced at corners of the site. Borings will be advanced to depths as follows: 3 to feet and 8 to 15 feet. Probes will be advanced to a depth of 13 feet. Infiltration testing in accordance with doee standards will be performed within the auger probes. Monitoring wells will be installed in the 3, 30-foot deep borings in accordance with doee requirements. Borings and probes will be abandoned in accordance with doee requirements.

1 Gallatin St Ne, Washington, Dc 20011
We will perform a total of eleven soil borings and five auger probes at the proposed site. The borings will be drilled utilizing 3. 25-inch hollow stem, continuous flight augers. The borings will be performed utilizing an atv mounted drill rig and will generate an approximately 6-inch annulus. Borings will be advanced to depths as follows: 6 borings to feet and 5 borings to feet. The five auger probes will be advanced to a depth of 8 feet. Backfill of the borings upon completion will be with bentonite slurry that has a mix design of two bentonite powder to one gallon of water.

1315 Clifton St Nw, Washington, Dc 20009
Ecs will employ a geoprobe direct-push drill rig to collect soil samples from 6 boring locations on the property. The resulting bore holes will be 2 inches in diameter. Soil borings will be advanced to 15 feet below grade. Investigation derived waste will be containerized, tested by a lab and shipped off-site for disposal. Borings will be abandoned with a bentonite slurry mix using a 2 to 1 ratio of bentonite powder to water.

12 3rd St Ne, Washington, Dc 20002
15 environmental soil borings will be advanced to 35- feet below grade, groundwater, or depth of planned excavation whichever is encountered first using a geoprobe drilling rig. The resulting bore holes will be 2 inches in diameter. Geotechnical soil borings will be advanced with a truck or atv mounted geotech drill rig. 5 will go to ftbg and 5 will go to 1 ftbg. The resulting bore holes will be 6 inches in diameter. Investigation derived waste will be containerized, tested by a lab, and shipped offsite for disposal. Borings will be abandoned with a bentonite slurry mix using a 2 to 1 ratio of bentonite powder to water.

5715 Broad Branch Rd Nw, Washington, Dc 20015
We will perform eight soil brings on the proposed site. The soil borings will each be advanced to a depth of feet. Additionally, four soil borings and four infiltration auger probes will be performed on the proposed site and will be advanced to depths of feet and 15 feet, respectively. The borings/auger probes will be located within the bounds of the property. The borings/auger probes will be drilled utilizing 3. 25-inch hollow stem, continuous flight augers. The borings/auger probes will be performed utilizing an atv and/or truck-mounted drill rig and will generate an approximate 6-inch annulus. After geotechnical exploration is completed, the borings/auger probes will be backfilled with bentonite slurry, which has a consistency of two pounds bentonite powder to one gallon water. Borehole/auger probe abandonment will be performed by tremie-grouting via a positive-displacement pump from the bottom of the borehole/auger probe.
