These results are usable as estimated values. <br /> Overall Summary <br /> The accuracy, precision, and sensitivity of the results were acceptable and all associated data are <br /> technically usable for project decisions with the above stated qualifications and blank actions taken. <br /> Table I(Data Summary Table) displays the analytical results that best represent the sample collected with <br /> the qualifications added and blank actions taken during the data usability assessment. For samples where <br /> more than one sample analysis was reported by the laboratory(e.g., dilution analyses), the data reviewer <br /> selected the single best result for each compound per sample and reported that result on Table 1. In <br /> addition, the sample results reported on Table I were rounded to two significant figures as required by <br /> the analytical method. <br /> l;Apr*cts\dq\9504100.mem 5 Gradient Carpormon <br /> TOTAL P.06 <br />
