L <br /> allowed to air dry, and reassembled. The use of phosphate-based cleaners, such as TSP, will <br /> not be allowed due to the documented laboratory analyses interference effects caused by the <br /> phosphate compounds in these types of cleaners. Purged water will be monitored for pH, <br /> temperature and conductivity. Purging will cease when temperature and conductivity readings <br /> have stabilized. Groundwater pH, conductivity and temperature will be documented during <br /> purging operations. <br /> The groundwater quality monitoring well will be sampled utilizing a decontaminated Teflon <br /> or stainless steel point-source bailer. Groundwater samples will be collected in laboratory- <br /> supplied containers at the base of the bailer via a Teflon check valve and nipple. Prior to <br /> initial use, the bailer will be disassembled, washed in a mixture of Liqui-Nox and clear water, <br /> rinsed in clear water, rinsed in distilled water, rinsed in deionized water, allowed to air dry, <br /> and reassembled. The use of phosphate-based cleaners, such as TSP, will not be allowed due <br /> to the documented laboratory analyses interference effects caused by the phosphate <br /> compounds in these types of cleaners. At the groundwater quality monitoring wells, a clean, <br /> unused bailer line will be utilized to lower and raise the bailer. <br /> Following transference, each sample container will be labeled, logged on a chain-of-custody <br /> form, and placed in an ice chest to be kept at 4°C during transport to a State of California <br /> certified analytical laboratory. Appendix D presents the proposed sampling and analytical <br /> protocol. <br /> Following completion of sampling activities and upon completion of laboratory analyses, a <br /> report describing these activities will be sent to the CVRWQCB along with the laboratory <br /> results. <br /> �gr,e-o�(m.z-x7 Page 6 <br />
