Control limits <br /> for precision (relative percent difference) range from U (identical <br /> duplicate DCS results) to the average, historical relative percent <br /> F ` difference + 3 standard deviation units. in cases where there is not <br /> enough historical data, EPA limits or advisory limits are set, with the <br /> approval of the Quality Assurance department. <br /> TV Analysis Results <br /> Test methods may include minor modifications of published EPA !Methods such <br /> ` as reporting limits or parameter lists. Reporting limits are adjusted to <br /> ,< reflect dilution of the sample, when appropriate. Solid and waste samples <br /> are reported on an "as received" basis; i.e., no correction is made for <br /> �• moisture content, unless the method requires or the client requests that <br /> such correction be made. <br /> Results are on the attached data sheets. <br /> F <br />
