REMINDER: The ICR data were collected as part of a national
research project to support development of national drinking water standards.
They should NOT be used to determine local water systems compliance with
drinking water standards, nor should they be used to make personal judgements
about individual health risks.
The ICR data were collected from July 1997 to December 1998. All the
data have been verified, and the database is complete. EPA will use the data to
identify national and regional patterns, not to reach system-by-system or
treatment plant-by-treatment plant conclusions. The data that you will see are
from individual samples. What EPA will evaluate is the degree to which the
samples represent overall water quality.
