About this file
The document is a well construction details diagram for the City of Clearwater's Class I Injection Well Annual Monitoring Report, specifically detailing the technical specifications for well IW-1. The diagram, prepared by WSP USA Inc. in February 2021, provides a comprehensive vertical cross-section illustrating the geological strata and well construction components from the surface to a depth of 1,100 feet. The diagram includes detailed information about the borehole diameters, steel casing specifications (ASTM-A139 Grade B), cement quantities, and the geological layers encountered, including the Undifferentiated Hawthorn Group, Tampa Member, Suwannee Limestone, Ocala Limestone, and Avon Park Formation.
The technical drawing shows precise details of the well's construction, including multiple casing sizes with varying wall thicknesses, ranging from 32-inch to 10.75-inch diameters. The well includes a 3-foot stickup above land surface with a welded flange cover and features a 10.75-inch diameter FRP injection tube (Red Box 1500). The geological cross-section reveals multiple semi-confining units and zones (Upper Zone A, Lower Zone A, Zone B, and Zone C) within the Upper Floridan Aquifer, with specific attention to the placement of cement and grout at different depths to ensure structural integrity and prevent cross-contamination between geological layers.
