EPA Approved Methods for Testing Drinking Water under the Total Coliform Rule

This is one reference for the analytical sampling methods approved by EPA for Drinking water.  This interprate as the methods needed to be used if potable water, dump tank water, etc is to be sampled for total coliform.  I thought this might be a useful tool as we move forward in gathering more information on the methods for anyalysis of water samples

From the publication: Analysis for the following contaminants shall be conducted in accordance with the methods in the following table or their equivalent as determined by
EPA. The methods and monitoring requirements for these contaminants are specified in 40 CFR 141.21. Additional methods are listed in Appendix A to
