“When the Cluster Rule regulations went into effect, we opted to bio-treat our collected methanol and HAPs in our ASB. We utilized a local lab to characterize the basin and perform the quarterly sample analysis. They went out of business after a few quarters, and we switched to another in-state lab. When we first began using the second lab, we were very pleased. The triplicate samples were much closer to each other, but after a few years the attention to detail seemed to start slipping. Finally one quarter, the batch of samples were all off by a similar percentage, and when confronted, the lab claimed the results were accurate. Weston helped us get to the bottom of the problem with some split samples; the other lab had a dilution problem in their calibration standards. We have been using Weston from that point on. Around here, we look at Weston as being the ‘Gold Standard’ to compare other labs to. Weston is professional, friendly, understanding, flexible, and responsive.”
