Eda 624 Case Study
From the above, here is what came out of the production meeting.
• Although EPA 624 does not require an MSD, I recommend you continue to run one when you have an extra (fourth) vial. This should meet any Waste Management contract requirement of spiking each sample during the year (I’m assuming the WM contract includes 624 samples – the main intent is to spike all groundwater samples during the year). Also, you could run a duplicate, which requires only one more vial, when you have a sample (possibly an influent or leachate) where you know there are target analytes.
• For EPA 8260, a duplicate can be used on one sample and a spike can be used on a different sample in a batch (run). When selecting this option, you want to select a duplicate
