TRANSCRIPT
Spreadsheet Overview of "Profile_Benchmark Calculator Short Form."
This spreadsheet is designed to help your system develop a disinfection profile and benchmark as required by the Long Term 1 Enhanced Surface Water Treatment Rule (LT1ESWTR). This spreadsheet will automatically calculate the weekly log inactivation, average monthly log
calculate the log inactivation provided by your system's treatment train based on various operating parameters (e.g., rate of flow, type of disinfectant, temperature, etc.). This report may assist you in determining whether a change in treatment process will benefit or adversely impact your ability to meet the disinfection requirements of the Surface Water Treatment Rule (SWTR). Note that you must determine the log inactivations of ALL treatment segments and not just those that are used for compliance with the SWTR.
Calculator Long Form."
In order for this spreadsheet to run properly, macros MUST be enabled in Microsoft Excel.
To successfully complete this spreadsheet, you need only enter the appropriate data for your system in the blue highlighted cells in columns F through L. The baffling factor must be entered in column I. Values for Columns H-L (residual conc., pH, etc.) must be entered for every week. The values in the remaining cells are automatically calculated by the spreadsheet. The example below demonstrates how a system with one disinfection segment consisting of one treatment stage, such as a clearwell, would enter data into the spreadsheet for the first three weeks of sample collection.
Systems using ozone as a disinfectant with certain configurations may not be able to use this spreadsheet. Ozone systems with co-current
concentration is greater than 0.3 mg/L. These systems also typically receive a credit of 1.0 log virus inactivation for the first chamber if the effluent ozone concentration is greater than 0.1 mg/L. However, this spreadsheet does not address ozone system configurations and does not use this method for calculating log inactivation. For more information on calculating log inactivation for systems using ozone, refer to Example D-3 in

This spreadsheet restricts values for pH, temperature, and chlorine residual concentration to those values included in the CT tables in the
error messages will occur: "check pH", "check temp", or "check residual". The "check residual" error message occurs if the free chlorine concentration entered is greater than 3.00 mg/L. The "check residual" error message is accompanied by the "Contact State" error message, indicating that you should contact your State if your system uses a free chlorine residual concentration greater than 3.00 mg/L to determine the
inactivation, and disinfection benchmark for both Giardia lamblia and viruses as achieved by your facility. The spreadsheet has been designed to

This spreadsheet will automatically determine the log inactivation of Giardia cysts by your system during peak hourly flow based on the following formulas:
Giardia log Inactivation = 3 x CTcalc / CT99.9

The algorithm for calculating CT99.99 for chlorine, chloramines, ozone, and chlorine dioxide was developed by the Cadmus Group, Inc. The
methods used were adapted from methods developed for 3-log Giardia lamblia inactivation (CT99.9) by Russell J. Topham with the Utah
screen (last tab after the "Virus Profile" tab). You will need Microsoft Word® to access the User's Guide.

Manual (Virus Log Inactivation = 4 x CTcalc / CT99.99) is inaccurate for chlorine dioxide. At inactivation levels significantly less than 4 logs this method
