Query: Drying up this mess.

I work for a small municipal wastewater plant, and used this (and Vol. II) as study material for the Class IV and Class III VA wastewater licensure test.It is:- Informative- Long windedIt is not:- Fun to read in the least- A very good reference manual- Very up to date on some thingsOverall the California State training books are recommended to me by more people than any other training courses. If you're doing this with the correspondence portion, you can get 2-3 "TC's" (2-3 months substitution experience) for at most a month of your time at less than an hour a day.
