A Technician Pumping Water from a Multi-Level Well

Detailed Description
A technician is pumping water from a multi-level well during an investigation of the natural attenuation of a chlorinated solvent plume under a fire training pit at the former Wurtsmith Air Force Base, Oscoda, Michigan. Tubing from the well leads to an in-line multi-parameter probe that records pH, dissolved oxygen, Eh, and temperature.
