Austin sits on the Balcones Fault Zone, a geological transition that creates complex soil conditions. About 12% of the city’s land has some degree of historical contamination from industrial sites or old fuel storage. We handle contaminated soil remediation in Austin from start to finish. Our team collects samples at depth using direct-push rigs and sends them to an accredited lab under EPA Method 8260 for VOCs and 8270 for SVOCs. For projects requiring immediate field data, we combine this work with a permeability test at the site to understand how fast contaminants might migrate through the clay-rich soils typical of the Blackland Prairie. We also check groundwater flow direction using monitoring wells. Every step follows ASTM D1586 for sampling consistency and ASTM D2487 for soil classification.
Austin’s clay-rich soils require careful sampling protocol — one wrong depth can misrepresent the entire plume.
