Past Project: Mercury in Soil Assessment, Montana and Wyoming

Olympus was contracted by a regional utility company to conduct environmental assessments at 474 active and inactive natural gas delivery metering stations for the presence of mercury. Site assessments were conducted through field screening of soil samples with a mercury vapor meter and immunoassay field kits and submittal of confirmation samples for laboratory analyses. The assessments identified that 144 of the original sites contained concentrations of mercury above regulatory cleanup thresholds. Based on results from the initial assessments and further assessments at select sites, Olympus developed and implemented a remedial action plan that removed mercury or reduced residual mercury concentrations to below regulatory thresholds.
