Project scope and field context
ATI Companies provided geotechnical drilling services to CDM Corporation for CERP, a long-range plan designed to restore and preserve the vast, complex Everglades ecosystem. Large-scale urban development and agriculture in the region have adversely impacted water quality and quantity and the distribution and timing of surface water flows in the system. To restore water storage capacity and reduce pollutant flow into the lake, CERP proposes to construct a series of aboveground reservoirs and storm water treatment areas with levees and pump stations, to be located throughout water basins north of Lake Okeechobee. In the Lemkin Creek area, north of the lake, ATI advanced a series of soil penetration test borings to 25 to 100 feet to characterize subsurface hydrogeologic conditions for one of the proposed levees and aboveground reservoirs. The borings were located both on land and in water. Primary investigation targets were semi-confining units within, and at the base of, the surficial aquifer, and paleo-karst features. ATI also installed piezometers and conducted aquifer performance tests.
