Red Hill Crisis Underscores Water Insecurity In Hawaii

(LK comment:  Jacob is right on…  In addition to conservation and reuse, Hawaii needs to begin to think about a Desal pilot program just in case.  The price of Desal has significantly decreased and we have seen what one Red Hill situation can cause and we have not seen the end of this crisis.) April 2022, Civil Beat Opinion Jacob Wiencek: Late last year a devastating water crisis hit Hawaii as thousands of gallons of fuel from the Red Hill Bulk Fuel Storage Facility leaked into the groundwater.

Thousands of mostly military families were relocated out of housing and the crisis worsened military-community relations given the preceding years of intense debate about the environmental impact of the facility.

However, most disturbingly it revealed a fundamental weakness that impacts not just Honolulu but all of Hawaii: our near single source dependence on underground aquifers presents an enduring threat to the state’s water security.

The Red Hill crisis is not the only water crisis to face Hawaii in the recent past. Maui County had to issue a water conservation noticethat inflamed an age-old debate about balancing water for residents and one of our primary economic pillars, tourism.

More broadly, the National Oceanic and Atmospheric Administration holds that the entire state of Hawaii is either in abnormally dry conditions or at least moderate to severe drought.

Whether through a man-made crisis or climate change we are facing increasing pressure on our water resources — and that pressure will only intensify as Hawaii’s population continues to grow (we clocked a 7% growth rate from 2010-2020).

For Honolulu, Rising Seas Deliver Flood Risks Three Ways

OCT 2020/Brett Walton, Circle of Blue/

Build a wall?

The biggest source of flooding linked to sea-level rise for Hawaii’s capital city comes not from the sea itself. It comes from underground.

It seems like an intuitive response for protecting a coastal city from rising seas. Just raise your external defenses. But the intuitive response, in certain cases, is also the wrong response, says Shellie Habel.

If the plan to prevent flooding in a city like Honolulu were to be simply block the ocean, “it’s not going to work,” Habel told Circle of Blue. Water has other, less obvious ways of invading, and that stealth movement has implications for water pollution and transportation in Hawaii’s largest city.

Habel is a coastal geologist with the Hawaii Department of Land and Natural Resources and Hawaii Sea Grant. She is the lead author on a study that investigated three flooding pathways in Honolulu, all of which are a consequence of rising seas. The study is the first to attribute the percent of flooded area in the city that is due to each factor individually and in combination. The likelihood that floods will come from multiple pathways simultaneously — and cause more infrastructure damage — rises along with the seas.

In Honolulu’s case, a sea wall would be a losing strategy against sea-level rise because a wall would not address the most serious flooding problem. The largest source of inundation for the city’s roughly 350,000 residents is not the ocean. It’s groundwater.

Habel and her colleagues found that little more than 2 to 3 percent of flooded area in Honolulu’s urban core is a result only of overland marine flooding. That range holds for the four sea-level elevations that the study looked at.

Groundwater flooding, by contrast, is the predominant individual source of flooding. How does this happen? Groundwater in the coastal region is hydrologically connected to the ocean. When the Pacific swells, so does the inland water table.

A hypothetical wall on the Honolulu waterfront would fail to prevent flooding, Habel said, because water would still bubble up from underground and come through backed up storm drains, which are the third flooding pathway. Groundwater flooding today swamps basements and roadways in low-lying areas and is noticeable in underground parking garages.

“So even if you put in a sea wall, even if you change the type of drainage management, you still have flooding,” she said, adding that a solution that only addresses marine flooding will not work because 97 percent of the total area that is projected to flood will still flood from rising groundwater and storm drain backups. Places like New Orleans and cities in the Netherlands, which also have groundwater flooding problems, employ pumps for that purpose. “In order to mitigate all the flooding you have to adapt to all three pathways.”

Worsening drought forces state of emergency in Puerto Rico

(July/ Editor Comments:  This could happen in Hawaii!!  Puerto Rico is roughly 1/2 the size of all the Hawaiian islands combined with double the population.  Like Hawaii, Puerto Rico’s options are pretty limited in a time of water scarcity although it is located closer to the mainland.)
By DÁNICA COTO; SAN JUAN, Puerto Rico (AP) — Puerto Rico’s governor on Monday declared a state of emergency as a worsening drought creeps across the U.S. territory amid a coronavirus pandemic.

Starting July 2, nearly 140,000 clients, including some in the capital of San Juan, will be without water for 24 hours every other day as part of strict rationing measures. Puerto Rico’s utilities company urged people to not excessively stockpile water because it would worsen the situation, and officials asked that everyone use masks and maintain social distancing if they seek water from one of 23 water trucks set up across the island.

“We’re asking people to please use moderation,” said Doriel Pagán, executive director of Puerto Rico’s Water and Sewer Authority, adding that she could not say how long the rationing measures will last.

Fernanda Ramos, a meteorologist with the U.S. National Weather Service in San Juan, said ongoing dry conditions will be interrupted by thunderstorms forecast to affect the island on Wednesday and Thursday.

“However, we are not expecting enough rain… to solve the problem we’re seeing,” she said.

More than 26% of the island is experiencing a severe drought and another 60% is under a moderate drought, according to the U.S. Drought Monitor. Water rationing measures affecting more than 16,000 clients were imposed earlier this month in some communities in the island’s northeast region.

Gov. Wanda Vázquez said 21 of 78 municipalities are affected by the severe drought while another 29 by the moderate drought. An additional 12 municipalities face abnormally dry conditions. The worst of the drought is concentrated in Puerto Rico’s southern region, which continues to be affected by aftershocks following a 6.0-magnitude earthquake that hit in early January and caused millions of dollars in damage.

An administrative order signed Monday prohibits certain activities in most municipalities including watering gardens during daylight hours, filling pools and using a hose or non-recycled water to wash cars. Those caught face fines ranging from $250 for residents to $2,500 for industries for a first violation.

Vázquez’s announcement comes amid criticism of her administration for not dredging reservoirs, which would eliminate sediment and avoid excess loss of water. Pagán said the utilities company has been in conversation with the U.S. Federal Emergency Management Agency since Hurricane Maria about a $300 million dredging investment. She blamed the lengthy process on the number of studies and analysis needed and that require FEMA’s approval.

How Water Footprints Can Help Us Eat Less Water

September 2019, (Editor Note: This article originally appeared in 2017 but is worth repeating because of its ability to demonstrate how much water we use without giving it much thought…  In the future, this will have to change or the lack of water will negatively impact the quality of our lives…) 

By Robin Madel and Kai Olson-Sawyer , Senior Research and Policy Analysts at GRACE Communications Foundation.

How  do we get Americans to conserve water? The first step is to show just much water it takes to make the average American’s lifestyle possible. But water conservation means a lot more than the typical advice to take shorter showers and wash fewer loads of laundry. While such actions are important, there are other ways to save much more.

Those who use GRACE Communications Foundation’s Water Footprint Calculator know that diet makes up the largest part of our individual water footprints. This is part of what’s called “virtual” water use, or the amount of water required to produce the food we eat, energy we use and the things we buy. Even though the water consumed to produce these items can’t be seen or felt, it comprises the majority of our water footprint.

Agriculture’s Big Water Footprint

In the United States, agriculture is a major surface and groundwater user. In fact, a full 80 percent of all consumptive water use in the US comes from agriculture. When the historic California drought hit two seasons ago, many were shocked by what were once considered arcane facts about the water used to produce our food. Headlines about how it takes just over one gallon of water to produce an almond were common.

Generally, the water footprint of fruits, vegetables, grains and pulses (like beans) is smaller than that of meat, dairy and nuts. Beef is the king of big water footprints: It takes about 1,800 gallons of water to produce one pound of beef. This is because cattle are physically large, have relatively long lives, eat so much food and are rather inefficient at converting feed to meat (compared to, say, chickens). In the United States, most beef cattle are raised on feedlots for a large portion of their lives, and while there, they eat feed made from grains like corn, sorghum, barley and oats – lots of it. It takes a tremendous amount of water to grow feed, especially the grains that go into cattle feed. This can be problematic for strained water resources when those crops are irrigated.

In addition to water for animal feed, how and where water is used has a large impact. Crops grown in areas with abundant rainfall tend to put less pressure on water resources. On the other hand, thirsty crops grown in arid locations or areas prone to drought can challenge sustainable water use when irrigation is necessary. There are additional challenges when vulnerable water sources are used to boost crop yields. For example, irrigation nearly doubled from 2002 to 2016 in the water-stressed Republican River basin through parts of Colorado, Nebraska and Kansas.

Competition between different types of water users is another source of trouble. A large share of US crops are grown in areas where such competition for water exists, as is the case in California and other arid Western states, the drought-prone Southeast and even the Great Plains where a major aquifer is being drained from agricultural overuse. Different sectors, including energy, industry, residential and the natural environment, all have specific water demands that compete with agriculture.

In the end, no location is immune from drought or water resource problems, even if only on a temporary basis. As rainfall and drought patterns continue to shift and intensify, water supplies will become increasingly stressed, which will have an inordinate effect on farming and food production. To use water more sustainably, farmers and food companies find that they must measure and understand how water is used along the production chain, which helps them recognize the extent of their water use and identify areas where they can cut back. At the same time, farmers, ranchers and other producers must be aware of water pollution that occurs within the process. This is important because pollution increases water use since more water is required to help clean up pollution.

Maps Show How Water Can Be a Precious Lifeline—or a Deadly Weapon

A new atlas by “guerrilla cartographers” explores the importance of water in everything from ancient mythology to modern warfare.

By Greg Miller (National Geographic)

ORIGINALLY PUBLISHED

In the recent conflicts in Iraq and Syria, water has often been used as a weapon. When ISIS seized the Fallujah Barrage, a dam on the Euphrates River, in 2014, they raised the floodgates to deprive downstream cities of water.

Later, they released water from the dam in an attempt to flood approaching Iraqi forces, which eventually recaptured the dam in 2016. (See “What You Need to Know About the World’s Water Wars.”)

Water touches every aspect of human life, sometimes in unexpected ways, says Darin Jensen, a cartographer at the University of California and founder of a nonprofit group called Guerrilla Cartography.

The group’s latest project, Water: An Atlas, takes an unconventional look at the importance of water through more than 80 maps, including one showing the sites where water has played a role in the conflict with ISIS (included in the gallery above).

The maps in the atlas come from artists, activists, academics, and other mapmakers. Like the group’s first atlas, which focused on food issues, it was a crowdsourced effort. Organizers picked the theme and solicited contributions.

US Government Releases First Global Water Strategy

December: By Brent Walton, Circle of Blue:

To coordinate its response to floods, droughts and disease and other water challenges whose political and economic challenges leap borders the Trump Administration submitted the Federal government’s first global water strategy.

Ordered by Congress, the strategy lays out four goals; to increases access to safe drinking water and sanitation, improve water management, protect watersheds from pollution, and prevent conflicts over river, lakes, aquifers that cross political boundaries.

“Safe water and sanitization are fundamental to solving challenges to human health, economic development and peace and security,” the 70 page report states.

US Climate Resilience Toolkit: Freshwater and Drought

October: (LK Comment: Found this excellent USG website recently which provides links to details about the effects of climate change in the Pacific and elsewhere.  This portion focuses on freshwater issues)

The ability of people, plants, and wildlife to thrive on Pacific islands is tied to the amount of precipitation each island receives. On time scales from months to decades, climate variability and change affect precipitation patterns across the region.  On even the smallest islands, freshwater is necessary to support plants, animals, and any human inhabitants. On developed islands, natural sources of water must also support agriculture, industry, and tourism. Relatively high demand for these uses means that water supply is constrained and may become more limited as climate changes.

Warming may lead to freshwater stress on many islands around the world

(Kobayashi comment:  This article in Nature is about a year old, but is especially key for freshwater planning for islands in the South Pacific and elsewhere.)

Scott and Lindsey:  May 2016

The millions of people—not to mention other animals and plants—living on islands already face unique challenges due to global warming. As seas rise and temperatures climb, islanders may have fewer choices for relocating people, infrastructure, or agriculture than larger countries do. Among the most serious public health and ecological threats facing islands may be freshwater stress. Nearly three-quarters of the islands examined in a recent study were projected to experience much drier conditions by 2050, with the situation worsening by 2090.

The bubble map at top right shows projected changes in freshwater stress by 2090 for 80 island groups around the world. Brown indicates increased freshwater stress, and green indicates decreased stress. The larger the dot, the larger the current population.

The bottom map shows small island groups that may be especially vulnerable by the end of the century due to a combination of drying and expected population growth. (Only the 22 island groups that had their own entry in the World Bank’s nation-specific population database were included in the second analysis.) The size of the dots on this map was determined by multiplying the projected change in freshwater stress in 2090 by the estimated population growth by 2050 (the farthest time horizon available for these islands).

Kris Karnauskas, the lead scientist on the research, explains that when he and his colleagues considered future rainfall changes alone, the models predicted that roughly 50% of small islands would get drier in a warming climate. But when it comes to freshwater stress, rainfall is only half the story. The other half is evaporation, and estimating evaporation from the land surfaces of small islands is something most global climate models—called GCMs, for short—don’t do.
