Cascade Drilling provides a full range of environmental and geotechnical drilling services. Regardless of the lithology or location, Cascade Drilling has the right equipment, experience, and specialized expertise to do the job. We offer sonic drilling and conventional drilling technologies. Our fleet includes track and truck mounted equipment and limited access rigs for tight spaces, low overhead conditions, and over-water work, allowing us to access almost any drill site.

Cascade Subsidiaries include TerraTherm, Aquifer Drilling & Testing, Panther Technologies and GeoSierra Environmental.

TerraTherm is a worldwide leader in the development and implementation of in situ and on‐site thermal remediation of organic contaminants. TerraTherm designs, builds and operates projects from concept to closure, using Thermal Conduction Heating (TCH), Steam Enhanced Extraction (SEE), Electrical Resistance Heating (ERH), and combinations of the technologies above.

Aquifer Drilling & Testing (ADT) provides environmental and geotechnical drilling for a variety of applications in the greater New York City area. ADT’s experienced drilling crews operate a diverse drilling fleet including sonic, auger, rotary and specialty equipment.

Panther Technologies, Inc. provides remedial services including conventional and innovative soil and groundwater remediation, hazardous and non-hazardous waste management and disposal, industrial landfill capping and lagoon closures, and mechanical system installations.

GeoSierra Environmental is best known for Trenchless PRB Placement technology for installing permeable reactive barriers (PRBs). In addition to Trenchless PRBs, GeoSierra is leveraging their technology and highly specialized groundwater expertise to tackle other difficult groundwater cleanup problems such as source remediation in fractured bedrock and remediation of stagnant plumes in fat clays.
