effect of water sampling techni-
ques on natural colloidal concentrations.

Accomplishments

This instrument has been success-
fully tested and proven as capable of determining the vertical and spatial distribution of local ground-
water velocity, both in magnitude and direction. The instrument can assess local flow velocities up to 15 mm/sec. Results were corrobor-
ated by baseline technique (aquifer pumping test). Presently the rate of flow cannot be deter-
mined as a real-time measurement in the field and work is on-going to develop this capability.

Collaboration/Technology Transfer

This technology was developed by Oak Ridge National Laboratory (ORNL) in partnership with R. J. Electronics. A prototype instrument was procured by Westinghouse Savannah River Company and is being used in environmental res-
toration activities onsite.
