Performing a Revised Total Coliform Assessment: Level 1 & 2

Sampling for total coliforms and E. coli in the water system is one of the most 
important things an operator can do. The new Revised Total Coliform Rule (RTCR)
effective April 2016 will affect every public water system. These revisions to the Total Coliform Rule
will affect how operators and mangers respond to total coliform positives (TC+) and require steps
to analyze the integrity of the system as a result of positive samples. Investigation and corrective
actions are at the forefront of the RTCR, and knowing how to complete a level 1 assessment can
be the difference between compliance and violation. This workshop will focus on reviewing triggers
for level 1 and level 2 assessments and who is expected to perform them, and how to conduct an
assessment with examples and small group exercises.

In this course attendees will learn: 

• Repeat sampling requirements
• New procedures for the month following a TC+
• What do I do if I have a positive E. coli result
• When is an assessment of a system needed
• How to complete a level 1 & 2 assessment of your system
• Tips on system inspection/investigation
