The objective of Task 40 is to identify and evaluate abandoned <br />and/or replacement wells for conversion to permanent monitoring wells. This task <br />would increase the number of wells in the State Engineers Office (SEO) water level <br />monitoring network and will help satisfy one of the SB-96-74 study recommendations to <br />increase the number of wells monitored for water levels in the Denver Basin Region. <br />This work was undertaken for the Colorado Water Conservation Board (CWCB), under <br />Phase 2 of the SPDSS by Camp Dresser & McKee (CDM). <br />This Technical Memorandum was undertaken under Task 40.2, and summarizes the <br />process used to identify wells scheduled for abandonment and evaluate identified wells <br />for conversion to monitoring wells in the Denver Basin Region. <br />Approach <br />The following table summarizes the sections contained in this technical memorandum. <br />Section Description <br />1.0 Process of Identifying Wells Scheduled for Replacement or Abandonment <br />2.0 Results of Identifying Wells Scheduled for Replacement <br />1.0 Process of Identifying Wells Scheduled for Replacement or Abandonment <br />CDM, the ground water contractor, worked with SEO staff to understand the well <br />abandonment and well replacement processes and to identify candidate wells that have <br />potential for conversion into a permanent monitoring well. The process involved several <br />steps as listed below. <br />
