1 <br /> Thermometers will be used and temperatures will be recorded. <br /> The sampling equipment will be thoroughly cleaned after each use with a PHS-EHD <br /> and CWQCB approved non-phosphate detergent and double rinsed. Equipment used <br /> throughout the drilling and sampling process will be steam-cleaned before the <br /> I start of each boring. There are two kinds of borings: infiltration borings and <br /> confirmation borings. Infiltration borings are those borings which are used in <br /> the application of H-10 product. Confirmation borings are those borings/wells <br /> placed between infiltration borings, not used in the remediation process, used <br /> to observe communication between infiltration borings. Infiltration borings will <br /> have temporary steel caps which will be removed after remediation and closed with <br /> six-sack sand cement grout to the existing grade. <br /> b. Water Sampling Protocol <br /> After purging, a bailer or other water sampling device will be decontaminated <br /> by cleaning with State approved non-phosphate detergent and double rinsed with <br /> distilled water. The bailer is then lowered into another monitoring well to <br /> obtain the water sample. The bailer and all attachments will be decontaminated <br />' between each sample. After, transferring the water sample to an appropriate sample <br /> ,far, the sample is labeled and then iced down for transport to a state certified <br /> laboratory. Each water sample will be recorded on a Chain--of-Custody form <br /> identifying the water sample, sampler' s initials, date, temperature, appropriate <br /> analytical tests, couriers used, and responsible laboratory personnel. <br />' 104 <br />
