MDBP Technical Guidances
Technical Guidances for Implementation of the
Microbial and Disinfection Byproducts Rules
These guidance manuals support the Interim Enhanced Surface Water Treatment
Rule and the Stage 1 Disinfectants/Disinfection Byproducts Rule. The manuals
will aid EPA, State agencies and affected public water systems in implementing
the two interrelated rules, and will help to ensure that implementation
among these groups is consistent. Unless otherwise noted, files are less than 800k.

Disinfection profile/CT spreadsheet
April 2001
* Note to users of previous versions of the spreadsheet: Spreadsheets
downloaded PRIOR to April 2001 give a divide by zero error in calculations
during months with less than 31 days. It is recommended that you use the
current version of the spreadsheet provided below.
- The following Excel spreadsheets can be used to calculate a 12-month profile
of Giardia or virus inactivation levels achieved with the use of Free Chlorine,
Chloramines, Chlorine Dioxide, and/or Ozone. These spreadsheets begin with
the month of April and end in March, as this was the regulatory timeframe for
required profiling under the IESWTR. Systems which have performed one year of
monitoring (April 2000 - March 2001) to comply with disinfection profiling
requirements only need to use the non-leap year file. Systems which are also
using historical data to create their profile will also need to use the leap
year version for the April 1999 - March 2000 timeframe to account for the
29-day February in 2000. Further information on how to use the spreadsheet
is provided in the file.

The Utah Department of Environmental Quality has also developed a spreadsheet
for calculating a disinfection profile. For more information,
