TM00-03 Changes in Minimum Reporting Levels for Suspended Solids Analyses at the NWQL (Lab Codes 49 and 169).

This technical memorandum announces changes, effective April 1, 2000, in minimum reporting levels for the suspended solids methods at the NWQL. The new reporting levels are based on blind blank data from the 1999 water year. Blind blank data were used in place of a spiked sample because reference standards are unavailable for this method.
