Signs warning of jellyfish are posted regularly in Waikiki.

But there is something else in the water that could soon trigger warnings either online or on the beach--- that the waters you are swimming, surfing, snorkeling, or paddling in-- are less than ideal.

The state posted these signs at Keehi Lagoon after a flash flood triggered by Tropical storm Darby raised the bacterial levels.

Now imagine seeing those warning signs across the state maybe even in lucrative Waikiki.

"Instead of solely focusing on when there is a sewage spill to activate posting of warning signs we are broadening our focus to other beach areas that may not have been posted in the past that exceed national recreational standard for eterococci bacteria, so in areas that are repeatedly exceeded, we will be notifying the public and posting permanent signage in those areas," said State Environmental Manager Stuart Yamada.

These signs along the Ala Wai were the first permanent signs the health department posted, not just because of bacteria levels but because of chemicals and heavy metals.

And other signs at Kahaluu warn of pollution due to what some believe is from overflowing cesspools.

Yamada said it’s not about closing beaches, or recreational areas but more about disclosure.

"Simply, it’s going to be about warning of high bacterial levels in various locations quite often you find them at stream mouths, beaches, or drainage pipes," said Yamada.

Drainage pipes like one that run under this wall and gazebo in Waikiki.

It’s an area known as the Kapahulu Groin. At certain times during the year the water quality isn't always the best.

In fact, the state says bacterial counts were elevated during the most recent rash of storms. And while the EPA’s reliance on eterococci as a possible fecal indicator may be the standard on the mainland, Yamada does underscore in the tropics it's a different game. The levels can be elevated due to rotting vegetation, animal waste, or soil runoff.

In the coming months, the state hopes to roll out a plan on what the signs will say and what the triggers will be-- and when, and where the warnings will be posted.

"We are hoping to educate people when they access our water quality website or see signs they will have a general understanding of whether it’s  likely to be the highest  water quality or where its poor because of bacteria,"

With that knowledge, then you can decide whether or not to go in the water.
