11.5.4.3 Cost Analysis for Case 3: Deep Barrier
The cost analyses for the three technologies considered in Case 3 are presented in Table
11.7
.
A summary of costs is presented in Table
11.8
.
As with the biobarrier in Case 2, the higher O&M costs are due to the need for amendment
additions every 3 years to provide a continuing supply of growth substrate for the dechlorinating
