SAGE provides a complete range of services related to the management of soil and groundwater contamination resulting from releases of petroleum products from Underground Storage Tanks (USTs), Aboveground Storage Tanks (ASTs) and other sources. SAGE is an approved consultant under Utah's Petroleum Storage Tank (PST) fund and provides both Utah-certified UST Consultants and Soil and Groundwater Samplers.

SAGE conducts investigations at facilities ranging from small commercial sites to large industrial operations. Our investigations may include evaluating and defining hydrogeologic parameters, identifying soil and groundwater contaminant concentrations and distributions, calculating free product volume, and conducting fate and transport modeling. If appropriate, we collect data necessary for the risk based closure and/or the development of natural attenuation remedial alternatives. If remediation is necessary, we prepare and implement Corrective Action Plans including such techniques as soil vapor extraction (SVE), high vacuum extraction (HVE), air sparging, and chemical oxidation. In cases where soil contamination is shallow and accessible, excavation is the simplest, quickest, and least expensive remediation option. Where soil vapor intrusion into buildings is an issue, vapor barriers or ventilation systems may be used.
