respectively), TDS (23.0 and 33.0 mg/L, respectively), and TOC (1.3 mg/L for both). Both samples had TOC detected at concentrations that was greater than the reporting limit, but less than five times the blank concentration, and was qualified as estimated (J). Sulfate and TDS were detected at concentrations that were greater than five times the blank sample concentrations, so the results were not qualified. • Equipment Rinse and Field Blank, collected on October 23, 2012, were associated with the analysis of five samples and had TOC detected at 0.1 and 0.2 mg/L, respectively. Two samples had TOC detected below the reporting limit and were qualified as non-detects (U) at the reporting limit. • Equipment Rinse and Field Blank, collected on October 24, 2012, were associated with the analysis of one sample and had TOC detected at 0.4 and 0.3 mg/L, respectively. Additionally, Equipment Rinse had TDS detected 5.0 mg/L. TOC was detected in the sample at a concentration that was greater than the reporting limit, but less than five times the blank concentration, and was qualified as estimated (J). TDS was detected in the sample at a concentration that was greater than five times the blank result, and therefore was not qualified. • Equipment Rinse and Field Blank, collected on October 25, 2012, were associated with the analysis of five samples and had TOC detected at 0.7 mg/L in both. Four samples had TOC detected below the reporting limit and were qualified as non-detects (U) at the reporting limit. The fifth sample had TOC detected at a concentration that was greater than five times the blank result, and therefore was not qualified. • Equipment Rinse and Field Blank, collected on October 29, 2012, were associated with the analysis of one sample and had TOC detected at 0.5 and 0.4 mg/L, respectively. TOC was detected below the reporting limit and was qualified as a non-detect(U)at the reporting limit. • One method blank associated with the TDS analysis of 16 samples collected October 23, 2012, contained 5 mg/L of TDS. TDS was detected all associated samples at concentrations that were greater than five times the blank result, so no data were qualified. All data submitted for this project are of known and acceptable quality as qualified, based on laboratory- established control limits and the data quality objectives. These data are considered acceptable for their intended purposes.
