Att_E_-_Well_Construction_Details.pdf

This document is a set of construction detail drawings prepared by Jacobson Helgoth Consultants for aeration proto-type wells. The drawings specify the construction specifications for four different extraction/injection wells (EW-1, EW-4, EW-5, and EW-6), each with a nominal 16-inch diameter borehole.

Each well construction detail provides comprehensive specifications for backfill materials, depths, casing types, and screen types across multiple intervals. The wells utilize materials including concrete grout seal, bentonite hole plugs, sand, and smooth grout at varying depths. The casing and screen components are consistently specified as 8-inch Schedule 40 PVC casing with 0.030 slot screens. The wells range in total depth from approximately 236 feet (EW-1) to 250 feet (EW-5, EW-6), with EW-4 extending to 240 feet. Each well is designed with multiple construction zones featuring different backfill materials and intervals to facilitate proper well functioning. The drawings were prepared in December 2001 with completion dates ranging from January 30, 2002 to December 6, 2001, and were drawn and checked by SRC and PFD respectively. These construction details serve as technical specifications for implementing the aeration well system design.
