“…Sodium and chloride, two primary nonradioactive contaminants, were discharged to the percolation ponds and stemmed from the ion exchange process. Although concentrations vary over the years, average concentration of sodium in wastewater was 103 mg/L during 1971 to 1973 (Barraclough and Jensen 1976). During 1996 to 1998, approximately 708,000 lb of sodium was discharged to the ponds.…”

“…Similar concentrations were reported in SWP-8 and SWP-13 (Tucker and Orr 1998). Barraclough and Jensen (1976) reported background concentrations of sodium in the SRPA as 8 to 10 mg/L. Discharge of chloride also varies over the years.…”

“…Soil pore-water sampling will begin at these locations in the spring of 1998; a time at which snow-melt and rainfall are most likely to produce conditions conducive to soil pore-water extraction. Soil sampling at the same depths and areas will occur in the spring at the same time [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] as the soil pore-water sampliig, and again in the fall at the same time as the soil sampling for the WI.& permit compliance.…”

“…Robertson and others (1974) described the regional hydrogeology and the influence of wastewater disposal on ground-water geochemistry for 1952-70, Barraclough and Jensen (1976) described hydrologic conditions during 1971-73, Barraclough and others (1982) for 1974-78, Lewis and Jensen (1985) for 1979-81, Pittman and others (1988) for 1982-85, Orr and Cecil (1991) for 1986-88, and Bartholomay and others (1995-91. Cecil and others (1991 also described the hydrogeology and influence of wastewater disposal in perched ground-water zones for 1986-88.…”
