MICROBIAL LABORATORY GUIDANCE MANUAL FOR THE LONG TERM 2 ENHANCED SURFACE WATER TREATMENT RULE (LT2ESWTR)
Impact/Purpose:
This manual will serve as an instruction manual for laboratories to use when collecting data for Crypto, E. coli and turbidity.
Description:
The Long-Term 2 Enhanced Surface Water Treatment Rule Laboratory Instruction Manual will be a compilation of all information needed by laboratories and field personnel to collect, analyze, and report the microbiological data required under the rule. The manual will provide laboratories with a single source of information that currently is available from various sources including the latest versions of Methods 1622 and 1623, including all approved, equivalent modifications; the procedures for E.coli methods approved for use under the LT2ESWTR; lists of vendor sources; data recording forms; data reporting requirements; information on the Laboratory Quality Assurance Evaluation Program for the Analysis of Cryptosporidium in Water; and sample collection procedures. Although most of this information is available elsewhere, a single, comprehensive compendium containing this information is needed to aid utilities and laboratories performing the sampling and analysis activities required under the LT2 rule.
