EPA 200.8 Heavy Metals Impact on Microbiological Water Safety Testing: A Comprehensive Guide

EPA 200.8 is a testing standard for the impact of heavy metals on microbiological water safety, developed by the United States Environmental Protection Agency (EPA). This standard is part of the EPAs Safe Drinking Water Act (SDWA) regulations and aims to protect public health by ensuring that drinking water meets certain standards for quality and safety.

Legal and Regulatory Framework

The SDWA requires drinking water utilities to test their water for various contaminants, including heavy metals. The EPA sets maximum allowable levels (MCLs) for these contaminants in the National Primary Drinking Water Regulations (NPDWR). For heavy metals, the MCLs are based on the EPAs Health-Based Exposure Limits (HBEL).

International and National Standards

Several international and national standards apply to this specific laboratory test:

  • ISO 6484: Water quality Determination of heavy metals

  • ASTM D3552-08: Standard Test Method for Analysis of Heavy Metals in Drinking Water

  • EN ISO 5963-1: Water quality Sampling, sample splitting and sub-sampling

  • TSE 5766: Turkish Standards Institution for water quality testing

    • Standard Development Organizations

    Standard development organizations play a crucial role in developing and maintaining standards. Some notable examples include:

  • American Society for Testing and Materials (ASTM)

  • International Organization for Standardization (ISO)

  • European Committee for Standardization (CEN)

    • Standard Evolution and Updates

    Standards evolve over time to reflect advances in technology, new research findings, and changes in regulatory requirements. Standard development organizations regularly review and update standards to ensure they remain relevant and effective.
