• 6.0 GEOSYNTHETIC CQA TESTING AND MONITORING
The following sections describe the CQA activities performed by Golder for the geomembrane
installed in the Phase IVa Area, and the geosynthetics installed in the LDT and Underdrains.
hi accordance with the Golder CQA Plan, when a Golder monitor observed deficiencies, the
monitor determined the nature and extent of the problem and notified Poly-Flex and/or CC&V.
When unsatisfactory test results identified a deficiency, Golder performed additional tests to
define the extent of the deficient azea. Poly-Flex corrected deficiencies to meet the
requirements of the specifications, and Golder retested and/or approved the corrected deficiency
prior to any additional related work. The following sections include discussions of the
deficiencies encountered.
