Laboratory Testing For BOD and CBOD

This 120 page manual on BOD testing, written by Perry Brake of the Washington Dept. of Ecology, and Mike Raynovic of NCL, gives valuable insights into troubleshooting BOD blanks, and GGA's, as well as the equipment involved.

Chapters on sampling, pretreatment, probe calibrations, dilution water, alternate procedures, correlation of BOD with other parameters, equipment, bench sheets, statistical considerations, and tips for troubleshooting. Over two years in the making, this work explains many of the so-called mysteries and corrects many of the common misconceptions and "old-wives tales" about this test. A systematic approach is presented for correcting dilution water blank problems, and GGA imprecision and bias, and a "BOD Checksheet" is provided to help the end-user assure that nothing has been missed.
