Written by Author of Course: Drinking and Finished drinking water are treated basically the same according to EPA. You must test the full 100ml sample volume and you only need to report coliform Presence/Absence, but results can be enumerated and both total and fecal coliforms must be confirmed. Surface and Raw Source drinking water are basically the same for the purpose of this discussion. You might test the full 100 ml sample volume, but it may not be necessary depending on what methodology you are using. Environmental, Ambient and Stream water are another group EPA treats as the same. They don’t require the full 100ml sample to be tested and confirmation is not always required for every analysis, but you need to enumerate your results. Consult the EPA website if you need further information on the types of waters your lab analyzes. When I use the term "must" it means that this criteria is required by the National Primary Drinking Water Regulations. The term "should" is used for practices while not specifically required by regulations, are considered good laboratory practice for quality assurance

Basic thru Intermediate

This course is a continuation of the Basic Microbiology course, Part 1. It will include all the basic techniques that were discussed in Part 1. It will mainly concentrate on the methods currently accepted by EPA to detect Total and Fecal Coliforms in Drinking Water. Some of these methods are also acceptable for testing Environmental Waters (non potable). Besides the step-by-step methodology I will include a discussion of each of the procedures, their pros and cons for many laboratories. Most of the procedures for Total and Fecal Coliforms include the primary testing method, and confirmatory test when required.
