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.

Opinion: House Bill 1326 Regarding Maui Stream Diversion

By Gary Hooser | April 21, 2019/ Star Advertiser Opinion:

In my 20 years of experience in government, politics and policy-making, House Bill 1326 is the most egregious example of special-interest legislation I have ever seen.

Fortunately the state Senate has taken time to listen to public concerns. After weighing both sides, conducting a thorough public hearing, asking tough questions and even visiting the Maui community most impacted, the Senate led by Water and Land Committee Chairman Kai Kahele has decided to shelve HB 1326.

Key Senate members have stated publicly they have no intention of passing HB 1326, but technically, it remains alive. Until the session ends May 2, anything can happen.

Alexander & Baldwin (A&B) stands to gain or lose $62 million, depending on the outcome of HB 1326. In essence, it is attempting to sell public trust water rights derived from stream diversions in east Maui. The intended beneficiary of this transaction is Mahi Pono — a California-based LLC, financed by a Canadian pension fund — which recently purchased the majority of A&B lands on Maui.

One fairly significant problem with this proposal is that A&B neither owns, nor has long-term control over this water.

In Hawaii, whether beneath the ground or flowing through our rivers and streams, water is a public trust resource. Businesses may use the resource, but must secure a permit that ensures sufficient water remains in the stream to preserve its natural ecosystem and that down-stream users also have access.

Yet this one company, the last remnant of the “Big 5” plantation era, and arguably the most politically powerful private landowner in Hawaii, is attempting, with the Legislature’s help, to secure those water rights without securing the proper long-term permits, and then transfer those water rights to Mahi Pono — pocketing a cool $62 million in the process.

The original HB 1326 proposed giving A&B and a handful of others an unlimited amount of time to divert an unlimited amount of water, without securing the permits and without ensuring environmental or down-stream user protections.

The present measure, HB 1326 House Draft 2, allows them 10 years, three of which have already passed, to comply with permitting requirements and convert their “temporary” one-year revocable permits (RPs) to proper long-term water leases.

Though A&B is the primary proponent and largest beneficiary of the measure, nine other RPs also are impacted by HB 1326 HD2, including some utilized by small ranchers and farmers.

The current controversy surrounding the plight of the small farmer and rancher is a manufactured crisis, perpetuated by the primary beneficiaries of HB 1326 HD2 and designed to promote fear and uncertainty.

The state Department of Land and Natural Resources (DLNR) has issued RPs to small users in the past without a problem. There is no specific legal impediment that prevents DLNR from extending the temporary RPs of these particular small farmers and ranchers while they pursue long-term leases.

The DLNR could provide certainty today, to all concerned by simply announcing its intent to continue extending the RPs of small users, so long as they demonstrate good faith and positive intent in pursuing a proper long-term water lease.

To his credit, Kahele, while acknowledging that DLNR could act unilaterally to resolve the situation, offered up a compromise that protected the little guy, while holding A&B accountable. Unfortunately, this overture was rejected.

The underlying problem is DLNR’s inability to manage the permit process. However, it’s neither the Legislature’s job nor in the public’s best interest to attempt to fix bad management with bad special-interest legislation.

And it’s certainly not the Legislature’s job to bail out a company that sold water rights it does not own.

It’s time the Legislature demand that the DLNR do its job. We, the collective community and the Legislature, need to move past the distraction and passions generated by HB 1326, and focus instead on the myriad other important bills begging for our time and attention.

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.

Hawaii’s record 2018 rains may foretell wetter times ahead

September: With warmer atmospheres and oceans, monster deluges may become ever more common there and elsewhere.
Matthew Cappucci: Science News for Students
Residents of Hawaii have survived several major deluges this year. And scientists say a warming climate may make such record-breakers ever more common.

One year ago, Hurricane Harvey shattered the U.S. record for most rain to come down in a single storm. Last month, another hurricane dropped record rains, this time on Hawaii. Named Lane, its measured tally would seem to be the highest ever for this island state, and second nationally only to what Harvey unleashed on Texas.

The previous record for a tropical cyclone in Hawaii was measured at Kanalohuluhulu Ranger Station. That was during Hurricane Hiki in 1950.

The National Weather Service in Honolulu has now confirmed that Lane dropped 132.13 centimeters (52.02 inches) of rain between August 22 and 26. That total comes from an official government rain gauge on the Big Island (named Hawaii). “The previous record was 132.08 centimeters (52.00 inches),” the NWS reported in an August 27 statement. This, it concluded, shows that “Hurricane Lane has broken the Hawaii tropical cyclone storm-total rainfall record.”

However, NWS pointed out, this record will stand only “pending verification.” Confirming the feat requires a special probe. A meteorologist at the NWS forecast office said that could take months.

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.

UH researchers link quality of coastal groundwater with reef

December;

(Honolulu, HI) Land-use practices on tropical oceanic islands can have large impacts on reef ecosystems, even in the absence of rivers and streams. Land-based pollutants, such as fertilizers and chemicals in wastewater, infiltrate into the groundwaters beneath land and eventually exit into nearshore ecosystems as submarine groundwater discharge (SGD)—seeping into the coastal zone beneath the ocean’s surface. In a study published recently in PLOS ONE, University of Hawai‘i at Mānoa (UHM) scientists used a combination of field experiments and chemical analysis of water and algae to show that the quality of coastal groundwater plays a major role in determining the health of nearshore ecosystems in Hawai‘i.

Various sources of pollution, such as agriculture or sewage treatment facilities, have identifiable chemical signatures, particularly the isotopes of nitrogen in the nutrients they contain. This study assessed groundwater quality, coastal water quality, and reef health across six different bays on Maui with various potential sources of pollution. By comparing the nitrogen isotope signature of algae tissues and potential pollution, the research group traced nutrients in the algae back to their land-based sources.

This study is the first to show the extent of the impact of wastewater injection wells at Kahului Wastewater Reclamation Facility, Maui’s highest-volume sewage treatment plant, on Kahului Bay. In addition to relatively high nutrient levels in marine surface waters in Kahului Bay, shallow areas were almost entirely dominated by a thick fleshy mat of colonial zoanthids, a phenomenon not reported anywhere else in the state. A concurrent companion study to this work, led by James Bishop at the UHM Department of Geology and Geophysics, found that water collected from beach sands, which represents coastal groundwater, next to the Kahului Wastewater Reclamation Facility contained up to 75 percent treated wastewater—highlighting the impact of wastewater in this area.

Researchers reveal cost-effective path to drought resiliency

July 2016

(Kobayashi Comment:  This intriguing Stanford study may offer an answer to Hawaii’s future freshwater shortages…  Imagine routing Hawaii’s torrents of stormwater into the ground aquifers instead of washing brown water pollution onto our beaches and recreation areas…)

Strained by drought in recent years, California desperately needs more resilient water supplies. An affordable solution that provides a wide range of benefits is within reach, according to a new Stanford study.

“We find that MAR is an effective and affordable way to balance local groundwater decisions with regional and statewide management,” said study co-author Debra Perrone, a postdoctoral scholar with Stanford’s Water in the West program.

Many local communities rely on statewide infrastructure to supplement their water supply. This water is costly and limited in supply, raising a need for cost-effective local storage options.

Managed aquifer recharge allows for local water storage, access and management to a much greater extent than large surface water reservoirs, which are often managed by state and federal entities. Although excess surface water can be limited in some regions of California, treated wastewater and urban stormwater offer sources for MAR that aren’t fully utilized by centralized surface water storage infrastructure.

MAR is particularly well suited to more populous and developed areas that can take advantage of large quantities of treated wastewater and stormwater runoff collected by extensive infrastructure for use in recharge. In more rural areas, MAR using excess surface water can still play an important role in replenishing groundwater basins and guarding against dry times.

“Every year, California lets 1 million acre-feet of treated wastewater flow to the ocean,” said co-author Melissa Rohde, previously a researcher with Water in the West. “Our research shows it would cost the state about $870 million to build the necessary MAR facilities to recover and store this water. That’s not a lot of money compared to the cost and energy required to transport water from large surface water projects or to desalinate ocean water.”

A water enigma

Groundwater supplies up to 60 percent of California’s water supply during dry years. Despite its crucial role in slaking the Golden State’s thirst, groundwater went largely unregulated until the 2014 passage of the Sustainable Groundwater Management Act. Therefore, statewide data on groundwater management generally and managed aquifer recharge projects specifically has been sparse or proprietary, generally not shared publicly.

This lack of information was highlighted with the 2015 passage of California’s largest-ever water-related proposition — the $7.5 billion Proposition 1. The bond promises almost $3 billion for water storage projects. Without data on relative costs and benefits, state and local water managers are hard pressed to make informed decisions on MAR projects.

In addition to new funding opportunities, the 2014 law puts the burden on local agencies for sustainably managing groundwater. So, local communities have more reason than ever to bank water sustainably. Managed aquifer recharge allows agencies to do that in ways tailored to a community’s resources.

Perrone and Rohde set out to identify costs and benefits of MAR projects around the state by mining applications for general obligation bonds from ballot propositions. In these publicly available forms, the researchers identified proposed economic costs and anticipated MAR project benefits. Then, they surveyed the projects’ managers to compare initial estimates with actual costs, and to identify advantages and limitations.

Looking to the future

As a changing climate, growing population and other factors put increasing pressures on water supplies, California’s need for long-term resilience will only intensify, the study noted. Conservation will only go so far. Flexible water storage options that can address changing conditions are essential. Therefore, it is likely that more water agencies will adopt MAR as a local management tool.

UH Gets $20 Million to Study Fresh Water Aquifers

13 May 2016, By Burt Lum, Civil Beat

You won’t find any argument among scientists, policy makers and the general public that fresh water is an extremely important natural resource.

I would argue that clean water is more important than oil, right up there next to clean air. And in Hawaii, we are especially blessed with some of the best water in the world.

Barry Usagawa, the administrator of the Honolulu Board of Water Supply’s Water Resource Program, told me, “Oahu’s drinking water quality is one of the best in the nation. Our fresh water comes from basal groundwater that is naturally purified, has high clarity and low mineral content, (is) very stable and needs very little treatment.  Oahu’s drinking water is as nature provides it to us.”

Our mauka forests and volcanic soil are well suited as a filtration system for rainwater, as it seeps through to underground freshwater aquifers. This process is slow, taking about 25 years for the rain water to journey through the mountain to form pools, or lenses, on top of salt water pools.

The added salts and minerals in ocean water makes it denser than fresh water, enabling fresh water to float on top of the salt water. That is why it is much easier to swim, float and tread water in the ocean than in a pool. The Honolulu Board of Water Supply pumps the water from these aquifers and distributes it to communities on Oahu.

I, for one, take a lot of this for granted. Turn on the faucet and out comes fresh, clean, spring-like water. The water from my home’s tap tastes like bottled water, so I rarely buy it unless I am prepping for hurricane season. I hardly give our fresh water a second thought and always expect it to be there. But water is a very precious natural commodity.

The National Science Foundation recognized this and awarded the University of Hawaii a five-year, $20 million grant to study the freshwater aquifers. This grant is part of the foundation’s Experimental Program to Stimulate Competitive Research.
