Evaluation of a flow diversion system for reducing /sup 90/Sr migration from SWSA 4 to White Oak Creek

“…The recognition of these problems spawned a number of field investigations of the SWSA 4 hydrology (Tamura et al 1980;Stueber et al 1981; Melroy and Huff 1985), all of which indicated the importance of runoff from the 35-acre area north of Lagoon Road as a contributing factor to the SWSA 4 water quality problems.…”

“…The second action took place in 1983 and consisted of a water diversion that routed drainage from Haw Ridge around SWSA 4. Flow measurements and stream sampling of the SWSA 4 tributary indicate reductions in the watershed area of SWSA 4 by 56%, the flow of SWSA 4 tributary by 56%, and the "Sr levels by 46% (Melroy and Huff 1985).…”

“…For the analysis presented below it is helpful to consider a mathematical function for radionuclide concentrations. It has been found that concentration, C, for a dissolved radionuclide is often correlated with discharge, Q, (see Melroy et al 1985, and. If the empirical relationship between C and Q can be established, then contamination discharge can be estimated from measurements of Q alone.…”
