We are experienced in many types of sampling and investigation techniques in support of site characterization, remediation, operation and maintenance and industrial applications. An overview of our investigation experience is listed below.

Groundwater:
  • Installation of monitoring wells, recovery wells, piezometers and lysimeters using hollow stem auger, mud rotary, air rotary and manual techniques.
  • Development of wells using pumps and surge, surge block, air surge and bailing techniques.
  • Groundwater sampling utilizing low-flow purging, direct push technology and bailing.
  • Aquifer testing including slug tests, pump tests, and cone penetrometer testing.
  • Water table and product level monitoring ranging from simple well gauging to advanced pressure transducer and data logger networks.
