Site Investigation and Remediation Services

WKA’s Site Investigation and Remediation Group conducts thorough and focused investigations of soils, air and groundwater to identify, delineate and remediate contamination sources. Our experienced team members evaluate impaired properties and generate essential data that clients need to make informed decisions about appropriate site-specific remediation approaches to attain compliance with federal, state and local regulatory agencies.
