2018 Ketchikan Annual Water Report

Some highlights:

As required by ADEC, -we send water samples every year to independent, certified laboratories
for analysis using the latest, modem equipment. When tested in 2001, all of the regulated
inorganic contaminants were at or below the minimum detectable limits (MDL) of the analytical
equipment. Since then, equipment accuracy has increased greatly and, when our water was
tested again in 2011, only minute amounts of barium, chromium, and thallium were found
present. All of the other inorganic contaminants still remained below the MDL. Note also that
the amounts of barium, chromium, and thallium that are present are all well below the EPA
maximum allowable levels (MCL) for these contaminants. The next set of inorganic analyses is
not due until after 2019.

Some people may be more vulnerable to contaminants in drinking water than the general
population. Immuno-compromised persons such as persons with cancer undergoing
chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other
immune system disorders, some elderly, and infants can be particularly at risk from infections.
These people should seek advice about drinking water from their health care providers.
EPA/Centers for Disease Control guidelines on appropriate means to lessen the risk of infection
by Cryptosporidium and other microbiological contaminants are available from the Safe
Drinking Water Hotline (800-426-4791).
