If the variance between the two readings is ever outside of the specified limits (0.1 mg/L or 15%, whichever is larger), the online chlorine residual analyzer should be calibrated and re-checked.

This public water system was required to conduct one year of disinfection profiling as part of the Long Term 1 Enhanced Surface Water Treatment Rule. The disinfection profile consists of inactivation calculations for Giardia and viruses calculated once per week over a year’s time. During this sanitary survey, a complete one year profile was not available for review. The system must collect information on the plant’s flow rate, contact tank volume, pH, temperature, and chlorine residual on at least a weekly basis to calculate Giardia and virus inactivation levels for one year. This information
should be used to complete the required one year disinfection profile and the profile should then be kept in the plant’s records indefinitely.

Inadequate inactivation design or operation (CT). The Surface Treatment Rule requires that water systems achieve at least 99.99% (4-log) removal and/or inactivation of viruses. The cartridge filtration system employed is not credited with any virus removal due to the large size of the pores in comparison with the size of viruses. In addition, the UV system is not credited with virus inactivation due to the relatively high UV resistance of viruses. The system must therefore achieve 99.99% inactivation of viruses through chemical disinfection. upon calculations made in this sanitary survey using conservative values, the
required level of virus inactivation is not achieved by the time the water reaches the first user. The system must ensure adequate inactivation; the disinfection profiling spreadsheet sent to the system should be used weekly for one year to document adequate inactivation. If the system is unable to achieve the required 4 log inactivation by adjusting the flow rate or chlorine residual, it is possible that modifications to the system design will be necessary. (SW > 3 logs? Inadequate inactivation design or operation (CT). The water treatment system operation and/ or design does not provide for adequate inactivation of Giardia lamblia. The SWTR requires that water systems achieve at least 99.9% (3-log) removal and/or inactivation of Giardia lamblia cysts and 99.99% (4-log) removal and/or inactivation of viruses. As documented in this sanitary survey, the filtration system when properly operated does not achieve the required reduction of Giardia; therefore, the system must achieve additional reduction of Giardia through inactivation.
