Title: Sampling and Analysis Plan for Environmental Control Number: Revision Date: Page 27 of 30 Groundwater Monitoring PUE.EN.D.026.04 2/19/2020 Tide: GCC Rio Grande Pueblo Plant Groundwater Control Number: Revision Date: Monitoring Well Compliance Sampling PUE.EN.P.003.01 2/1812020 Page 3 of 4 Alternatively,the labeling may be made by writing directly on the bottles. Information shall include: • Site or project name(GCC Rio Grande) • Sample ID • Sample collection date and time • Sampler's initials c) Bail to fill at least %the 1-gallon new, disposable poly cubitainer, which is the sample transfer container to be used for this groundwater bailer sample collection methodology. d) Load the 3/8" peristaltic tubing through the peristaltic pump head unit per manufacturer's instructions, keeping both tubing ends from touching any contaminating materials. e) Insert one end of the 3/8" peristaltic pump tubing into the cubitainer, keeping this suction end submerged. f) Attach the inlet side of the 0.45 pm filter(observe flow arrow on filter)to the other end of the peristaltic pump tubing. g) Operate the peristaltic pump per manufacturer's instructions producing water to flush air from the 0.45 pm filter and fill with sample water until the filter is producing water. Confirm there are no visible particulates flowing in the water from the filter outlet. h) Fill the 125 ml poly preserved bottle to the bottleneck and cap immediately. There is acid preservative in this container. Do not over-fill or spill the preservative—if this does happen then take a replacement 125 ml poly preserved bottle from a spare bottle set and repeat fill procedure. i) Fill the 250 ml poly unpreserved bottle from the 0.45 pm filter outlet to the bottleneck and cap immediately. j) Stop the peristaltic pump and remove the tubing from the cubitainer. k) Fill the 500 ml poly unpreserved bottle to the neck directly from the cubitainer and immediately cap. 1) Label each bottle with actual the sample time, coordinated with the final logged water quality field parameters readings. m) IF AT ANY POINT A BOTTLE CAP GETS DROPPED ON THE GROUND, RAINED ON, ETC.—simply triple rinse the cap(inside and out)with excess sample water from the bailer to decontaminate. Bail more water if necessary. Confirm no debris is on the cap and then screw it onto the bottle. If the cap is dropped into a known or suspected contaminant,then do not take a chance and simply replace the contaminated cap from a bottle from a spare bottle set. 11)Collect QAIQC field duplicate sample a) For each quarterly compliance groundwater monitoring event(up to 10 monitoring locations to meet 10% minimum QA/QC standard), one randomly selected, blind duplicate sample shall be collected and submitted for laboratory analysis by the"GW-Compliance"suite. b) Fill the bottles for the duplicate sample in sequence of the"normal" sample that is being duplicated by using the procedure instep 10. Batching is recommended for efficiency with field-filtered samples. c) Name the sample a unique ID(to make the sample ID is"blind"from the lab)and assign it a time +/- one hour of the duplicated sample collection time, also to aid in keeping the sample identification blind from the lab. 12) Rig down sampling equipment a) Reel up WLI and decontaminate probe and tape exposed to water with Liquinox solution spray and spray-rinse with distilled water. b) Place used bailer and cord, 0.45 pm filter, tubing, cubitainer and miscellaneous consumables into a trash bag for appropriate disposal. c) Decontaminate multi-parameter water quality meter probes by spraying with Liquinox solution followed by spraying with distilled water until no suds remain. Prepare meter probes for long-term storage per manufacturer's instructions. 13) Prep sample for submittal to analytical lab
