Rig and Tooling Options to Address Site/Project Challenges at the Hanford Nuclear Reservation in Support of Groundwater Remediation

The Hanford Nuclear Reservation is located in southeastern Washington State and covers approximately 586 square miles. Past nuclear weapon production activities at the Site resulted in approximately 450 billion gallons of liquid waste being released to the ground. In support of a large scale pump-and-treat remediation system to reduce the mass of carbon tetrachloride, Cascade Drilling L.P. (Cascade) has been providing drilling services to The Soil and Groundwater Remediation Project to install multiple injection and extraction wells over the last 9 years, specifically in the 200-ZP-1 operable unit 1. Cascade managed multiple site specific requirements, including; difficult and variable site specific geology, special site-specific health & safety requirements, and extraordinary contaminants (carbon tetrachloride, chromium, nitrates, iodine-129, cobalt-60, cesium-137, nickel-63, carbon-14, strontium-90, technetium-99, tritium, and uranium). These issues all lead to development of specially approved drilling methods and tooling which were used to achieve high quality driven soil samples and discrete groundwater samples in addition to the injection and extraction well completions.
