Dccrp proposes to drill 3 environmental borings, nebbd-15e, nebbd-16e and nebbd-17e located in the median between rhode island ave nw, 6th st. Nw and r st. Nw. The borings will be 6 inches in diameter and up to feet deep. The work will take up to two weeks to complete and will require extended work time of 7am to 7pm. The work will not impact pedestrians, trees or parking meters.

Dccr project proposes to drill 1 direct push boring nebbd-66e located west of 1703 6th street nw. The dp borings will be 2 inches in diameter and extend feet below ground surface. The borings will be completed using direct push methods with a standard hollow soil rod to collect soil samples. Groundwater samples may be collected via a peristaltic pump. Samples will be analyzed for tph-dro, tph-gro, voc, svoc, rcra metals (plus vanadium), pesticides, herbicides and pcbs. All drill cuttings will be containerized in 55 gallon dot rated steel drums. All drill cuttings will be properly tested and characterized for disposal. The dp borings will be backfilled with hydrated bentonite. Monitoring wells will not be installed. When the boring is complete, we fill the borehole approximately 1 4 full of bentonite pellets then add approximately 5 gallons of water to hydrate bentonite in the borehole. The boring is then filled approximately 3 4 full with pellets and water is again added to the borehol

Propose 1 geotechnical boring and monitoring well, nebbc-43, located in median of 6th st. Nw and r st. Nw intersection. The boring will be 6 inches diameter and approximately 137 feet deep. The work time will be approximately 2 weeks and the work will require 24 7 occupancy of the work area. A full work time between 7am and 7pm is also required. The monitoring well will remain for up to 5 years. The work will not impact the parking meters or trees.

Propose one geotechnical boring (nebbc-44) located in the median of r street nw and rhode island ave nw. The boring will be 6 inches diameter and 137 feet deep. A vibrating wire piezometer will be installed upon boring completion and will remain for up to 5 years. The work will take approximately 2 weeks to complete and will require 24 7 occupancy and full work time between 7a and 7pm. The work area will not impact parking meters or trees but will require a sidewalk closure and detour.

Dccr proposes one geotechnical boring (nebbc-44) located in the right lane of the southbound 6th street nw. The boring will be 6 inches diameter and 124 feet deep. A monitoring well will be installed at feet below ground surface. A vibrating wire piezometer will be installed at approximately feet below ground surface. The greater than screened interval will allow for greater draw down in the event of a pump test. A permanent steel casing will be installed and socketed into the potomac clays. If environmentally impacted soils are encountered, soils will be drummed, characterized and disposed of appropriately. See idw management plan and attached schematics for additional information.
