USEPA Approved

The United States Environmental Protection Agency (USEPA) establishes limits
for maximum contamination levels of certain constituents in water. It also
requires that specific methodology be used to analyze for these constituents.
Sometimes the USEPA develops these methods; more often, the USEPA
evaluates methods developed by manufacturers, professional groups, and
public agencies such as:
