DID YOU KNOW

Workers will be onsite this week to prepare for the first phase of the Sitewide Odor Assessment at Ascon. Soil borings, each roughly 3 inches in diameter and of depths between ~3–20 feet, will be collected using a truck-mounted drill rig. These soil borings will be analyzed in laboratories to identify areas of the Site that may have the potential to generate odor during future cleanup work at Ascon. The field investigation will provide technical information that will determine specific treatability actions to further mitigate potential odor. There may be periodic noise from the soil boring equipment. Read more about the Odor Assessment field work here.

A truck-mounted drill rig, like the one above, will be used onsite during the Odor Assessment work.
