The LT2ESWTR Microbial Toolbox
is a Web tool that can help utilities meet requirements of the Long-Term 2 Enhanced Surface Water Treatment Rule by determining which treatment is most suitable for their water treatment plant. The Toolbox serves as a decision tree tool that will guide you through several steps to attain
credits associated with the LT2ESWTR. Based on the information you enter, the program will select the treatment options suitable to your treatment facility from a broad range of both new and established technologies and programs. The Toolbox, which was developed by Environmental Engineering and Technology Inc. as part of a Water Research Foundation project, features help screens, cost estimates, and other information to help you evaluate whether selected items are applicable for your particular site. Developed as part of project 2750, and updated by project 4068 in early 2007, the updated tool is now available to the public.
