An Environmental Working
Group analysis of tap water tests from 1998
through 2002 shows that customers of Lenoir City
Utility Board drank water containing up to 9
pollutants. Lenoir City Utility Board is one of
65,000 water suppliers across the country
wrestling with treating water polluted by
sprawl, sewage, factory farms, and industry.

Over health based limits |
| Note: Some
pollutants may be in more than one
category. |
NOTE: Health based
limits included in this analysis include
enforceable drinking water limits (called
Maximum Contaminant Limits, or MCLs) as well as
governmental, non-enforceable health guidelines,
such as Maximum Contaminant Limit Goals (MCLGs),
lifetime health advisory levels, one-day and
ten-day advisory levels to protect children from
non-cancer health endpoints, and other
government-established health guidelines for tap
water contaminants.
Health Summary
Contaminants found in your tap water (1998 -
2002): 9
Health effects or target organs of
contaminants found: Cardiovascular or Blood
Toxicity, Cancer, Developmental Toxicity,
Endocrine Toxicity, Kidney Toxicity,
Gastrointestinal or Liver Toxicity,

Information on violations
is drawn directly from EPA's national violations
database in the Agency's Safe Drinking Water
Information System. Analyses by others have
raised questions about the quality of the
information in EPA's database. For the purposes
of this investigation, EWG is not showing below
or including in our analyses, those violations
for individual water suppliers that occurred on
days for which the total number of violations
assigned by EPA to that water supplier was
greater than 20. This criteria was based on
common characteristics of incorrect violations
data as identified by water utilities, from a
review of EPA's violations data by several
hundred utilities prior to the release of EWG's
investigation.
