There will a construction crew working at the Knickerbocker site tomorrow, June 22, 2012, from approximately 8 a.m. to 5 p.m. They will be drilling seven (7) groundwater wells 6-8 feet deep using an excavator with a small drill rig. It will generate some construction noise. The wells will be capped when they’re done.
There will be another crew there next week to hand-dig three (3) additional shallow wells, approximately 2-3 feet deep, for devices that will show the elevation of the stream. All work will be done next to the stream and not in the water itself
