State recreational water quality officials are
alerting the public that initial testing at an oceanside site in
northern Avon showed levels of bacteria exceeding the state’s and
Environmental Protection Agency’s recreational water quality swimming
The alert is for waters at the public beach
access at ramp 34, and was issued on September 5. Test results of water
samples collected yesterday show bacteria levels of 111 enterococci per
100 milliliters of water, which exceeds the state and federal
single-sample standard of 104 enterococci per 100 milliliters for Tier
1 high-usage sites. Swimming areas are classified based on recreational
use and are referred to as tiers.
This alert is not a beach closing, nor is the alert for the entire Avon area.
State officials will test the site again, and the
results of the sampling will dictate further action. If the new samples
also show elevated bacteria counts, state officials will post a
swimming advisory sign and issue a swimming advisory.
The N.C. Recreational Water Quality Program tests
water quality at ocean and sound beaches in accordance with federal and
Enterococci, the bacteria group used for testing,
are found in the intestines of warm-blooded animals. While it is not
known to cause illness, scientific studies indicate that enterococci
may indicate the presence of other disease-causing organisms. People
swimming or playing in waters with bacteria levels higher than the
standards have an increased risk of developing gastrointestinal illness
or skin infections.
State officials sample 209 sites throughout the
coastal region, most of them on a weekly basis from April to October.
Testing continues on a reduced schedule during the rest of the year,
when the waters are colder.
