North Hempstead Landfill Hydrogeologic Investigation
Port Washington, NY
LKB developed and implemented the NYSDEC Part 360 hydrogeologic investigation for closure of this State Superfund site, located adjacent to a Town park and golf course and overlying a sole-source aquifer. The scope of work included a detailed review of existing data, preparation of a work plan, installing and sampling ground water monitoring wells, preparing a detailed report of the findings, and preparing a post-closure monitoring plan. During the course of this work,LKB discovered a previously unknown shallow clay layer that was overlooked by other consultants, which limited the vertical extent of the Uppermost Aquifer and thereby greatly reduced the extent and cost of post-closure monitoring required to be performed.
