BODBook

During 20 years working with the Washington Department of Ecology's Environmental Laboratory Accreditation Program, I found the biochemical oxygen demand (BOD) analysis and its derivative, the carbonaceous BOD (CBOD) test, to be especially challenging for many analysts. Several years ago, I co-authored a book on the test with Mike Raynovic of North Central Labs (NCL) of Wisconsin, our goal being to remove much of the mystery from the BOD test. That book, Laboratory Testing for BOD and CBOD, is still available (www.nclabs.com).

Since publication of Laboratory Testing for BOD and CBOD, I have learned even more about the test through evaluation and re-evaluation of hundreds of labs doing BOD and CBOD. Also, the 21st Edition of Standard Methods for the Examination of Water and Wastewater, recently approved by the U.S. Environmental Protection Agency for compliance testing, makes several changes to the BOD test. Wanting to make that additional knowledge and a summary of the 21st Edition changes available to the masses, I have written another BOD book...or booklet if you prefer. To minimize cost to the user, I self-published (with help from Kinko's) the 54-page book and am selling it for $15 a copy (or $13 each for orders of 10 or more) plus shipping if applicable. The book emphasizes the fact that the BOD test is controlled primarily by a bunch of unpredictable and

sometimes troublesome bacteria. In thinking through the

problems commonly encountered in the test, I sometimes

find it helpful to think like a bacterium...hence the name of

the book, A Bug's-Eye-View of the BOD Test, and its

healthy- and hungry-looking mascot.

The 54 pages of text are filled with explanations of confusing passages in Standard Methods 5210B, warnings about common pitfalls, and suggestions for overcoming problems. A troubleshooting guide focuses common problems, suggests causes, and recommends potential corrective actions. But perhaps more valuable that the text itself is a supplementary compact disk (CD) that comes with each book. On it are interactive Microsoft Excel® files that calculate BOD results for both the bottle and graduated cylinder methods, Excel® files that automate construction and use of precision control charts, a comprehensive checklist keyed to paragraphs in the text, a tutorial on statistics as they apply to the BOD test, copies of pertinent EPA and NELAC documents, and various other helpful documents. Files on the CD are updated periodically, are not copyrighted, and may be used at will. Many of the files can be accessed at a web page I call "BOD Solutions", but if you are interested in the rest of them, check out the entire contents of the booklet and its supplementary CD here. The book was last updated in June 2010.

I am probably a little prejudiced, but I think this book is a must-have for those who want to recover from problems they are encountering with the BOD or CBOD test, or want to avoid problems in the future.
