Hilo Water Quality Advisory for October 20th, 2020

High Bacteria Count Advisory has been Canceled for the Exit of Ice Pond in Hilo.

Published by: HIRSC - Hawaii Island (Holualoa) Team


From the Department of Health (DOH) - Clean Water Branch (CWB):

The Water Quality Advisory for Exit of Ice Pond, Hawai‘i has been canceled. Water sample testing results show that the enterococci levels no longer exceed the threshold level.


The advisory for this beach is posted because testing for enterococci indicates 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. 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.

Fortunately, while swimming-related illnesses can be unpleasant, they are usually not very serious - they usually require little or no treatment or get better quickly upon treatment, and they usually have no long-term health effects. The most common illness associated with swimming in water polluted by fecal pathogens is gastroenteritis. It occurs in a variety of forms that can have one or more of the following symptoms: nausea, vomiting, stomachache, diarrhea, headache, or fever.

Other minor illnesses associated with swimming include ear, eye, nose, and throat infections. In highly polluted water, swimmers may occasionally be exposed to more serious diseases. Not all illnesses from a day at the beach are from swimming. Food poisoning from improperly refrigerated picnic lunches may also have some of the same symptoms as swimming-related illnesses, including stomachache, nausea, vomiting, and diarrhea.

At any given time and place, we are constantly exposed to a variety of microorganisms that have the potential of making us ill. The beach has been posted and this advisory will remain in effect until water sample results no longer exceed the threshold level of 130 enterococci per 100 mL.
