SHN oversees all technical requirements on each environmental site investigation and remediation project. We strive to anticipate the work required so we can plan the technical aspects of the project and deliver our work products on time and within budget. Services such as risk based corrective action and monitored natural attenuation (MNA) have resulted in substantial cost savings on many of our clients' projects.

SHN was the first company to use the membrane interface probe (MIP) in Humboldt County to collect real-time data on soil type and relative contaminant concentrations.
