Water advisory canceled for Honokohau Harbor waters

Update: Health officials on Friday canceled the high bacteria count advisory for the southern end of Honokohau Harbor in North Kona after water sample testing results show that the enterococci levels no longer exceed the threshold level.

Health officials on Thursday issued a high bacteria count advisory for the southern end of Honokohau Harbor in North Kona.


The advisory was issued due to high levels of enterococci found in a sampling of ocean water from the area, the Department of Health’s Clean Water Branch reported.

Levels of 178 enterococci per 100 mL were detected during routine beach monitoring. The EPA sets the threshold for enterococci at 130 enterococci per 100 mL.

“The advisory for this beach is posted because testing for enterococci indicate that potentially harmful microorganisms such as bacteria, viruses, protozoa, or parasites may be present in the water. Swimming at beaches with pollution in the water may make you ill,” the advisory reads.

The advisory will remain in effect until water sample results no longer exceed the threshold level of 130 enterococci per 100 mL, according to the department.


Enterococci are indicators of the presence of fecal material in water and, therefore, of the possible presence of disease-causing bacteria, viruses, and protozoa, according to the EPA.

Children, the elderly, and people with weakened immune systems are the most likely populations to develop illnesses or infections after coming into contact with polluted water, usually while swimming, according to the department. The most common illness associated with swimming in water polluted by fecal pathogens is gastroenteritis. In highly polluted water, swimmers may occasionally be exposed to more serious diseases.
