We've gone from monitoring 33 to 29 sites!

2/19/2021

0 Comments

 
Since September 2020, the Hui has been able to pause one additional site in West Maui (Olowalu Shore Front) and three sites in South Maui (Kilohana Dr., Keawakapu Beach, & Ulua Park), bringing us from 33 to 29 sites monitored for nearshore water quality. The Hui pauses the monitoring of sites for one or more of the following reasons: we have a good understanding of their water quality dynamics, these sites have little to no pollution or fluctuation, no management is currently underway for contributing land based pollution, and/or no permanent funding is available to continue monitoring these sites.

Part of this shift to monitor fewer sites allows the Hui to expand our efforts into some other water quality research and working with partners to delve deeper into some of the pollution “hot spots” our data has helped identify.

Monitoring continues at the following sites, thanks to the work of our wonderful volunteers and Team Leaders!

As of August 2020, Hui O Ka Wai Ola has gone from monitoring 41 to 33 sites! After looking closely at the data our volunteers have gathered since June 2016, the Technical Committee recommended eight sites to “pause” and one site to discontinue for one or more of the following reasons: we have a good understanding of their water quality dynamics, these sites have little to no pollution or fluctuation, no management is currently underway for contributing land based pollution, and/or no permanent funding is available to continue monitoring these sites. The Committee also added one site, Kahekili Two, which is north of the previously monitored Kahekili Beach Park site and is closer to the influence of the Lahaina Wastewater Treatment facility.

Sites currently paused are:
  1. Olowalu Point
  2. Ukumehame Park
  3. Sugar Beach
  4. Mai Poina Park
  5. Palauea Beach
  6. Po'olenalena Park (Chang's)
  7. Mākena Landing
  8. One'uli Beach
Sites recently discontinued are:
  1. Pāpalaua Park
Sites recently added are:
  1. Kahekili Two

With fewer sites to monitor, we have moved from 4 survey teams in West Maui and 4 teams in South Maui to 3 teams on each side. The teams are currently monitoring the following sites  every three weeks year-round:
WEST MAUI

Research Report: Changes in Water Quality During a 12 Hour Period at Two Maui Beaches

5/27/2020

0 Comments

 
To better understand how tide change influences water quality, a group of Hui O Ka Wai Ola Team Leaders spent a full day in December 2019 (approximately 12 hours) measuring water quality parameters hourly at Cove Park in South Maui and Hanaka‘ō‘ō Park (Canoe Beach) in West Maui – a deviation from the Hui’s usual practice of monitoring 41 sites once every three weeks only in the morning.
 
During this one day study, as well as with our regular ocean water quality monitoring year-round, we measure nutrient levels. Nutrients, including nitrogen and phosphorus, can indicate pollution from wastewater, run-off from agriculture, landscaping and/or golf courses. Once in the ocean, these nutrients can lead to an overgrowth of algae. Algae, particularly invasive species, quickly out-compete corals for sunlight and overrun large tracts of living reef.
 
Nutrient values can vary a lot over the course of a tide cycle -- low nutrient levels at high tide and higher nutrient levels at low tide. Sites with higher nutrient levels acquire these nutrients via ground water that comes into the ocean as underground "springs.”
 
The fact that there is fresh water coming in from underground springs over the course of a day is shown by the change in salinity readings. This explains the ever-shifting levels that we see from the data we collect once every three weeks at each site.
 
During our one day experiment we took 4 nutrient samples, with the first sample at high tide and the last sample near low tide.  The accompanying chart (Figure 1) shows how salinity decreases as the tide goes out and the fresh water from underground springs comes in, while the nitrate levels increase as the amount of fresh water increases. 
 
Our ongoing Hui O Ka Wai Ola water quality sampling program was designed to catch a variety of tide states so that we can understand not only the average level of nutrients but also the range of nutrient levels each site exhibits. 
 
Another interesting observation is that other parameters vary during the day as well -- temperature rises as the sun comes up and heats the top layer of water and then starts to decrease as the sun goes down or if clouds come over (Figure 2). During our one-day experiment, temperatures varied over 2 degrees centigrade during the course of the day.

With our ongoing water quality monitoring, we are careful that we measure this parameter at each site at approximately the same time of day every time we sample so that seasonal temperature variations can be distinguished from diurnal variations. 
 
Finally, dissolved oxygen (DO) and pH levels also vary across the course of a day. Dissolved oxygen is needed for aquatic plants and animals to survive. Corals are very sensitive to changes in ocean chemistry, including increased ocean water acidity (which results in a drop in pH levels).
 
During our 12 hour study, we found that in Cove Park and Hanaka‘ō‘ō Park these diurnal variations are not as obvious because of the influx of fresh ground water as the tide is going out which also affects levels of pH and DO. In general, pH and DO are at their lowest levels just as the sun rises due to the fact that photosynthesis has not been taking place overnight. CO2 levels rise at night as marine organisms respire, taking in oxygen and producing CO2. There is no photosynthesis at night so as CO2 levels rise, the water becomes more acidic and pH levels drop. Dissolved oxygen also drops because of a lack of photosynthesis that generates oxygen as a bi-product. Once the sun begins to rise, photosynthesis begins again, and the pH and DO levels rise.

Water quality monitoring  during COVID-19

5/11/2020

1 Comment

 
As of Monday, May 4, a small group of Hui O Ka Wai Ola staff members are monitoring coastal water quality at all 41 of our leeward Maui sample sites every three weeks. Sampling has been on hold since March 16 due to safety concerns during the COVID-19 pandemic. However, permission was recently granted from Maui County officials for our group to continue this essential work.
 
Working in teams of two, the Hui’s Project Manager and Team Leaders are following strict guidelines to maintain a six-foot distance from each other, wearing face masks and sanitizing while collecting and processing samples.
 
We are grateful to be monitoring at this unprecedented time when island activity is at an all-time low. We hope to learn if the decrease in visitors and changes in behavior may impact coastal water quality.
 
We plan to maintain this monitoring protocol for the next two months and hope to get our amazing volunteers back in the field as soon as it is safe to do so.

Maui Preparatory School Students Participate in Water Quality Testing Program

2/3/2020

1 Comment

 
Our ocean water quality testing program, Hui O Ka Wai Ola, is made possible through the dedication of more than 35 adult volunteers who monitor water quality at 41 local beaches every three weeks.

And now, we're excited to report a new water quality monitoring partnership with students from Maui Preparatory Academy, reports James Strickland, Project Manager for Hui O Ka Wai Ola. 

Eight middle school students are conducting turbidity sampling in Napili Bay as part of their Project Based Learning program.  Based on student input, they have sectioned off the bay into four 250 foot increments and are sampling each of the four sites at two depths (2 feet and 6 feet).

We're grateful for these students and their dedication to monitoring ocean water quality, as a step toward achieving cleaner ocean water for Maui's coastlines. ​

Hui O Ka Wai Ola is the 
Recipient of Funds Raised at September Meeting of 
“100+ Women Who Care – Maui”

Michelle Griffoul, a volunteer with the Hui O Ka Wai Ola water quality testing program and board member of Maui Nui Marine Resource Council, beams after learning that the water quality testing program would receive the donations collected at the September meeting of  100+ Women Who Care - Maui. ​
Hui O Ka Wai Ola was awarded $12,500 in funds raised at the September 2018 meeting of “100+ Women Who Care – Maui,” a group that holds quarterly meetings to raise funds for local nonprofits, charities and causes.  

According to the 100+ Women Who Care – Maui website, the group’s members meet four times each year, with each meeting lasting one hour. Each member (and their guest) brings a check for $100 or more. Any member can nominate local charities, non-profits, or worthy causes, whose names are put into a hat. Three names are drawn at random. The group then votes by secret ballot to choose one of the organizations or causes to support, with a collective donation that typically amounts to $10,000 or more. 

Michelle Griffoul, a member of 100+ Women Who Care – Maui and a board member of Maui Nui Marine Resource Council, nominated the organization’s Hui O Ka Wai Ola (Association of Living Waters) ocean water quality testing program. She spoke from the heart about her firsthand experience as a volunteer with this innovative monitoring program, which works with dozens of local volunteers to regularly test ocean water quality at 39 locations along the south and west coastlines of Maui. 

The members voted by secret ballot and selected Maui Nui Marine Resource Council as the recipient of the funds raised at the meeting. 

“We’re grateful to all of the community-minded women in this group who chose to support our Hui O Ka Wai Ola water quality testing program,” says Robin Newbold, MNMRC co-founder and chair. “Maui Nui Marine Resource Council is proud to be a co-manager of this unique program and we are grateful for all in our community who make it possible. Clean ocean water is essential for healthy coral reefs. It’s also important to visitors and residents who enjoy swimming, snorkeling, diving, paddling, fishing and surfing along Maui’s coasts,” said Newbold. “Our ocean water quality testing program and the data it generates is critical in our work for clean ocean water for Maui.”
