F <br /> tle: GCC Rio Grande Pueblo Plant Groundwater Control Number: Revision Date:onitoring Well Compliance Sampling PUE.EN.P.003.01 2/19/2020 Page 5 of 6 <br /> I) Label each bottle with actual the sample time, coordinated with the final logged water <br /> quality field parameters readings. <br /> m) IF AT ANY POINT A BOTTLE CAP GETS DROPPED ON THE GROUND, RAINED ON, ETC. — <br /> simply triple rinse the cap (inside and out) with excess sample water from the bailer to <br /> decontaminate. Bail more water if necessary. Confirm no debris is on the cap and then <br /> screw it onto the bottle. If the cap is dropped into a known or suspected contaminant, <br /> then do not take a chance and simply replace the contaminated cap from a bottle from a <br /> spare bottle set. <br /> 11) Collect QA/QC field duplicate sample <br /> a) For each quarterly compliance groundwater monitoring event (up to 10 monitoring <br /> locations to meet 10% minimum QA/QC standard), one randomly selected, blind <br /> duplicate sample shall be collected and submitted for laboratory analysis by the "GW- <br /> Compliance"suite. <br /> b) Fill the bottles for the duplicate sample in sequence of the"normal' sample that is being <br /> duplicated by using the procedure in step 10. Batching is recommended for efficiency <br /> with field-filtered samples. <br /> c) Name the sample a unique ID (to make the sample ID is "blind"from the lab) and assign <br /> it a time+/-one hour of the duplicated sample collection time,also to aid in keeping the <br /> sample identification blind from the lab. <br /> 12) Rig down sampling equipment <br /> a) Reel up WLI and decontaminate probe and tape exposed to water with Liquinox solution <br /> spray and spray-rinse with distilled water. <br /> b) Place used bailer and cord, 0.45 µm filter, tubing, cubitainer and miscellaneous <br /> consumables into a trash bag for appropriate disposal. <br /> c) Decontaminate multi-parameter water quality meter probes by spraying with Liquinox <br /> solution followed by spraying with distilled water until no suds remain. Prepare meter <br /> probes for long-term storage per manufacturer's instructions. <br /> 13) Prep sample for submittal to analytical lab <br /> a) Note laboratory analysis holding times for "GW-Compliance" suite, specifically <br /> nitrite/nitrate analysis which requires samples to be received by lab within 48 hours of <br /> the sample collection time. This requires each sample to be shipped by overnight service <br /> by the conclusion of the day it was collected! <br /> b) Place all 3 filled and labeled sample bottles into the original lab-provided bottle set bag <br /> or otherwise a gallon-size Ziploc bag and place in cooler under ice. Label bag with the <br /> same information on the individual bottle labeling in indelible ink. Ice should be in <br /> multiple gallon-size Ziploc bags. Package so that all bottles are secure to prevent <br /> movement during shipping. It is very important that these samples get under ice as soon <br /> as possible after collection and arrive to the lab between 0°C - 4°C. NEVER DUAL- <br /> PURPOSE THE SAMPLE COOLER FOR FOOD OR DRINKS! <br /> c) Complete the Chain of Custody(COC)for the lab using the official sample ID,the sample <br /> date and time, the matrix"Groundwater" checked,the number of containers (3). Enter <br /> "GW-Compliance" for analysis request and check the box.
