Hawaii First Water

Fearing Contamination, Honolulu Has Slowed Pumping At A Well Near Red Hill

Civil Beat, Christina Jedra, December 1 2021, As officials wait for answers about the source of petroleum contamination in the water near Red Hill, the Honolulu Board of Water Supply is pumping water from one of its wells, the Halawa shaft, at half the rate it normally does as a “precautionary measure,” the agency said on Wednesday.

The water board typically pumps 10 million gallons per day from the Halawa shaft, which provides water to over 400,000 people from Moanalua to Hawaii Kai – over 20% of the water for the area.

As of Wednesday, it was pumping at a rate of 5 million gallons per day.

The move shows that the island agency in charge of delivering clean water to metropolitan Honolulu and beyond is taking seriously the possibility that the island’s drinking water could be at risk.

“Right now, it almost looks like a disaster unfolding before our eyes,” Board of Water Supply Chief Engineer Ernie Lau said.

The Board of Water Supply slowed its pumping amid reports that military housing residents are being sickened by water that smells like fuel and after the Navy stopped pumping at its own Red Hill shaft on Sunday.

On Wednesday, the Hawaii Department of Health announced that preliminary testing detected petroleum in a water sample from Red Hill Elementary School but said details and the source of the problem are still under investigation.

Without the announcement of an official cause, residents have wondered whether their symptoms are connected to a 14,000-gallon spill of fuel and water from a pipeline a quarter-mile downhill from the Red Hill fuel facility on Nov. 20. The World War II-era fuel farm is made up of 20 massive tanks and a system of pipelines, and the Red Hill water shaft is located a half-mile away.

Kahele Tells Navy That Red Hill Is ‘Crisis Of Astronomical Proportions’

Civil Beat, Nick Grube, December, (LK Comment:  State of Hawaii water officials have raised their concerns about the Red Hill Fuel tanks and their slow leaks for decades, but the Navy has downplayed the problems and has been slow in remediating the issue) WASHINGTON — Hawaii Rep. Kai Kahele demanded answers from a top Navy official Thursday about petroleum contamination in the drinking water at Red Hill on Oahu.

Kahele asked Vice Admiral Rick Williamson, who was testifying before the House Armed Services Committee, about how the Navy planned to respond to the crisis, which so far has resulted in almost 100,000 people being told not to drink tap water while federal, state and county officials scramble to respond.

“The Navy is currently experiencing a crisis of astronomical proportions in Hawaii,” Kahele said. “People are getting sick, animals are getting sick and our military families need answers. The island of Oahu needs answers.”

(Big Island) Council eyes state support for wastewater issues

October, MICHAEL BRESTOVANSKY Hawaii Tribune-Herald:  The County Council is urging the state to seek solutions for the mounting wastewater problems on Hawaii Island.

A resolution discussed at Wednesday’s council meeting would urge the state legislature to set funding for wastewater management projects around the state as one of its legislative goals next year.

Hamakua Council-woman Heather Kimball, who introduced the resolution and waived its prior reading at committee, said the county is facing very expensive and necessary wastewater projects that it cannot finance alone, and called for the state to develop possible systems that could support those projects in cooperation with the county.

“We need $1 billion for facilities improvement, another $1 billion for cesspool conversion,” Kimball said, citing estimates from the county Department of Environmental Management. “Are we going to put that on the taxpayers?”

The day before, at a meeting of the Regenerative Agriculture, Water, Energy and Environmental Management Committee, Environmental Management Director Ramzi Mansour said the county is facing the monumental challenge of converting the bulk of the county’s housing developments away from cesspool systems. But because there are only about 15,000 users of the county’s sewer service, the department isn’t receiving enough fees to fund such a conversion.

Furthermore, Mansour said, 86% of all equipment at the Hilo Wastewater Treatment Plant needs to be either replaced or repaired. Similarly, 65% of the equipment at Kula‘imano Wastewater Treatment Plant is failing, as is 72% of the equipment at the plant in Papaikou.

10/21/21-PARTICIPATE IN “IMAGINE A DAY WITHOUT WATER”

(October 2021) (DLNR/Honolulu) – Imagine a Day Without Water, on Oct. 21 is a day to pause and reflect on the value of water in our daily lives. COVID-19 and the climate crisis have underscored the critical role that natural and man-made water systems play in our communities. They protect our health and safeguard the environment. DLNR is partnering with the Honolulu Board of Water Supply for this nationwide awareness event.

Not having water is a reality for many people. Across Hawai‘i, some families still lack access to reliable and safe drinking water. They eagerly await the next rainstorm so they can collect and filter the water that falls on their rooftops. During periods of prolonged drought, their only options are filling containers at remote stations or paying high prices to have water delivered to their home. “Some rural communities in Hawai‘i actually live without water security,” explained Commission on Water Resource Management (CWRM) Deputy Kaleo Manuel. “Streams continue to be diverted that impact instream biota and traditional and customary rights, water rates are increasing on private and public water systems, and some families have to make real decisions about whether to pay for electricity or water .”

‘It’s Not Sexy’: Kahele Eyes Overdue Hawaii Projects For Biden’s Jobs Plan

April 2021/ Civil Beat, Nick Grube: Before U.S. Rep. Kai Kahele returned to Washington last week, he joined professional surfer Laird Hamilton for a boat tour of the Hanalei River on Kauai.

Hamilton pointed out the invasive hau bush along the riverbanks and talked to the congressman about the heavy rains that erode the hillsides and submerge the roadways, occasionally cutting off the tiny North Shore community from the rest of the island.

Kahele also witnessed the disappearing shorelines caused by coastal erosion and rising sea levels triggered by climate change.

A freshman lawmaker who sits on the House Transportation and Infrastructure Committee, Kahele wanted to see firsthand how Hawaii’s bridges, roads and highways were holding up so that he could report back to his colleagues how much money the state might need should Congress pass President Joe Biden’s $2.3 trillion infrastructure plan.

What Kahele saw, however, was not pretty.

In an interview with Civil Beat, Kahele described walking through a decades-old wastewater treatment plant that he thinks might be the “worst in the country” and visiting waterfronts where treated sewage is dumped onto the shoreline “right onto the rocks.”

“It’s not sexy,” Kahele said. “But if you saw what I saw you would know this is something we need to address.”

Water Scarcity: A National Security Challenge

April 2021:  (Comment:  here is a piece that I co-authored about the international dimensions of the freshwater scarcity problem and implications for US national security)

Climate change is responsible for an unprecedented rise in tropical cyclones and other extreme-weather events, but related threats are also manifesting. According to a February 2021 study, rising temperatures may be responsible for a six-month summer in the Northern Hemisphere by 2100. A longer summer means greater water consumption. (Remember running through the sprinkler as a kid? Those days may be numbered.) Higher temperatures may also fuel longer, more frequent droughts and alter rainfall patterns that further degrade the environment and disrupt the water cycle.

Combined with a burgeoning global population and increased water demand for agricultural and urban purposes, the United States must brace for dwindling supplies of fresh water domestically and worldwide. In an unclassified memo released last year, the National Intelligence Council projected global water usage to increase by as much as 50 percent by 2050 as the world’s population grows by 1.5 billion. Already, there are 2 billion people with limited or unreliable access to sufficient supplies of clean water, according to the memo.

The Intelligence Community’s attention to global water security is understandable. As the single most critical resource to public health, food supplies, and energy production, the scarcity of fresh water portends escalating international competition for its availability. A September 2020 study by the World Resources Institute recorded 2015 as the first year with more than 20 interstate conflicts over water resources; within three years, that number more than doubled.

Scientific breakthrough: First images of freshwater plumes at sea

March 2021: University of Hawaii: The first imaging of substantial freshwater plumes west of Hawaiʻi Island may help water planners to optimize sustainable yields and aquifer storage calculations. University of Hawaiʻi at Mānoa researchers demonstrated a new method to detect freshwater plumes between the seafloor and ocean surface in a study recently published in Geophysical Research Letters.

The research, supported by the Hawaiʻi EPSCoR ʻIke Wai project, is the first to demonstrate that surface-towed marine controlled-source electromagnetic (CSEM) imaging can be used to map oceanic freshwater plumes in high-resolution. It is an extension of the groundbreaking discovery of freshwater beneath the seafloor in 2020. Both are important findings in a world facing climate change, where freshwater is vital for preserving public health, agricultural yields, economic strategies, and ecosystem functions.

EPA requires seven Kauai cesspools to be closed to protect groundwater, fines Hawai‘i DLNR again

(March ’21)

Four prior EPA enforcement actions against Hawai‘i DLNR have closed 74 cesspools, collected $407,400 in fines

(Comment:  Closing “large” cesspools is a good start on closing the 90,000 individual cesspools on the islands by the State’s mandated 2050 goal)

HONOLULU – The U.S. Environmental Protection Agency (EPA) has taken enforcement action on Kauai to direct the closure of seven large-capacity cesspools (LCCs) and collect $221,670 in fines from the Hawai‘i Department of Land and Natural Resources (DLNR). In 2005 EPA banned LCCs, which can pollute water resources, under the Safe Drinking Water Act.

“EPA has taken several actions against Hawai’i DLNR and encouraged them to conduct an audit of all remaining properties to identify any remaining illegal large capacity cesspools to prevent future fines,” said EPA Pacific Southwest Regional Director of Enforcement and Compliance Assurance Amy Miller. “Large-capacity cesspools can contaminate our groundwater, streams and ocean resources. EPA will continue efforts to identify, fine and close all remaining LCCs in Hawaii.”

EPA is authorized to issue compliance orders and/or assess penalties to violators of the Safe Drinking Water Act’s LCC regulations. EPA’s enforcement action to close LCCs owned by DLNR is based on an August 2019 inspection and additional submitted information. The enforcement action includes the following DLNR properties:

  • Camp Hale Koa: Located in the Kokee Mountain State Park, EPA found three LCCs associated with the campgrounds. A non-profit organization leases the property from DLNR and operates the land parcel as a camping property that is available for daily or weekly group camping. These cesspools have been closed.
  • Waineke Cabins: Also located in the Kokee Mountain State Park, EPA found two LCCs serving the cabins. The United Church of Christ, under its Hawaii Conference Foundation body, leases the property from DLNR and operates the land parcel as a group camping property. These cesspools have been closed.
  • Kukui Street commercial property: Located in the town of Kapaʻa, EPA discovered two LCCs serving 4569 Kukui Street. aFein Holdings, LLC, leases the property from DLNR and operates the land parcel as a multi-tenant commercial property. The Kukui property must close the cesspool by June 30, 2022.

Since the 2005 LCC ban, more than 3,600 LCCs in Hawaii have been closed; however, many hundreds remain in operation. Cesspools collect and release untreated raw sewage into the ground, where disease-causing pathogens and harmful chemicals can contaminate groundwater, streams, and the ocean. Groundwater provides 95% of all local water supply in Hawaii, where cesspools are used more widely than in any other state.

How Efforts To Save Hawaii’s Forests Are Preventing A ‘Freshwater Crisis’

February ’21 repeat of an excellent September ’20 Civil Beat article by Claire Caulfield.  (Larry note:  this is a great report on why the forests play a major role in filling the aquifers in Hawaii)

When Serene Smalley hikes into the Koolau mountains, her goal is to kill as many plants as possible. Armed with a machete and syringes full of herbicide earlier this summer, her sights were set on the mule’s foot fern: a giant Jurassic-looking plant.

Smalley pulled out her cellphone, scrolling through a map app with hundreds of white pins. Each GPS marker pins the suspected location of a mule’s foot fern. A local conservationist spent weeks during the pandemic combing through satellite images and identifying the GPS coordinates of mule’s foot ferns on the mountain range.

Serene Smalley uses a machete to fell branches of the fern before injecting a small amount of pesticide into the base of the plant.

To the untrained eye, a mule’s foot fern can look like a native plant, the hapuu fern. “The hapuu is very lacy and pretty,” she said, while the fond of the invasive fern is pointed. “Which reminds me of a snake.”

Some of the offending ferns are right off the Poamoho Ridge Trail near Wahiawa, but to reach others she will have to scale steep slopes in the rain. Smalley invested $60 in specialized shoes that look like hooves and have metal spikes embedded in the soles for traction. They were designed for fishermen and she uses duct tape to stabilize her ankles for the long hike ahead.

For six years Smalley has been scaling mountains, camping on remote peaks and navigating mudslides to kill thousands of non-native plants. She’s one of only about a dozen elite volunteers trusted by the state Department of Land and Natural Resources to assist in the dangerous task of eradicating invasive plants from the nearly 2.2 million acres of protected forests across the state.

“I can definitely see progress,” Smalley said. “It’s very, very rewarding.”

Oahu Watersheds Poamoho Wahiawa Summit Wide

Watersheds provide clean drinking water, carbon sequestration and help prevent floods and droughts. A University of Hawaii study estimated the Koolau Range provides between $7.4 billion and $14 billion in value to the state.

These volunteers, along with hundreds of state employees, dozens of environmental groups and an army of local hunters are fighting an uphill battle to protect Hawaii’s forests — and Hawaii’s drinking water.

Hawaii’s Fresh Water Leaks to the Ocean Through Underground Rivers

(Nov ’20) By Matt Kaplan, NYT.

There are few things on the island of Hawaii that are more valuable than fresh water. This is not because the island is dry. There is plenty of rain. The trouble is that there is tremendous demand for this water and much of it that does accumulate on the island’s surface disappears before it can be used.

New research by marine geophysicists reveals that underground rivers running off the large island’s western coast are a key force behind this vanishing act.

Fresh water is often pumped on the island from aquifers formed from rain at higher elevations where it is easy to access. The drawback is that if too much water gets pumped to meet demand, little remains to travel through rocks to farms and fragile ecosystems that depend upon it. To make matters worse, recent studies of this water labeled with isotopes and tracked over time have revealed that these aquifers are also heavily leaking somewhere else.

“Everyone assumed that this missing fresh water was seeping out at the coastline or traveling laterally along the island,” said Eric Attias, a postdoctoral researcher at the University of Hawaii, who led the new study published Wednesday in Science Advances. “But I had a hunch that the leak might be subsurface and offshore.”

The big island of Hawaii is like an iceberg. Only a tiny fraction of the island sticks out of the ocean. The rest is submerged. To study the hydrogeology of these sections, Dr. Attias turned to electromagnetic imaging.
Ocean water conducts electricity exceptionally well because of the presence of dissolved salt ions. By comparison, fresh water is a rather poor conductor. Aware of these different electrical properties, Dr. Attias worked with a team at Scripps Institute of Oceanography to tow a 3,200-foot long system behind a boat that emitted electromagnetic fields down through the submerged coastal rocks near Hualalai volcano on the west coast.

Dr. Attias’ work shows that within the rock of the island below the waves, there are underground rivers of fresh water flowing 2-½ miles out into the ocean. These rivers are flowing through fractured volcanic rock and surrounded by porous rocks that are saturated with salt water. Between all of this salt water and the flowing fresh water are thin layers of rock formed from compacted ash and soil that appear to be impermeable and thus keeping the two types of water separated. In total, these rivers appear to contain enough fresh water to fill about 1.4 million Olympic swimming pools.
