Appendix_3_-_As-Built_Completion_Log.pdf

This document is an As-Built Completion Log for an LFG (Landfill Gas) Extraction Well (W-34R) at the Palo Alto Landfill, prepared on 11-8-13. The log details the technical specifications and construction details of a groundwater monitoring well, including a precise vertical profile of the well's components. The well was drilled with a 24-inch borehole diameter and features a 4-inch solid/perforated PVC casing with a total well casing depth of 49 feet and a total borehole depth of 50 feet.

The well construction includes specific layering components such as a 4" PVC top cap, soil backfill, 4" hide pipe, bentonite seals, a gravel pack, and a perforated 4" HDPE pipe with an end cap. The log meticulously records measured depths for key structural elements including the top of bentonite, backfill, soil, gravel, and screen, with design and as-built measurements matching exactly. The document provides a detailed technical representation of the well's vertical composition, serving as a critical record for the landfill's gas extraction and monitoring infrastructure.
