Hawaii First Water

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.

UH research essential in federal Clean Water Act ruling

June, Cindy Knapman/UH: The U.S. Supreme Court ruled in April that the federal Clean Water Act, which regulates the discharge of pollutants into the nation’s surface waters, including lakes, rivers, streams, wetlands and coastal areas, must also consider pollutant inputs to those waters by groundwater. This ruling was based on scientific findings from researchers at the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST).

Over the last decade, Maui coral reefs have experienced a decline in health and overgrowth by invasive algae. Concerns arose that submarine groundwater discharge was carrying nutrients from wastewater infrastructure to nearby coral reefs, contributing to this decline. However, the quantity and locations of submarine groundwater discharge along Maui’s coasts were poorly known. It was also unclear whether the groundwater carried high concentrations of nutrient or other pollution.

SOEST researchers from the Department of Earth Sciences were awarded grants from the U.S. Environmental Protection Agency and U.S. Army Engineer Research and Development Center to investigate the hydrological connections between deep injected effluent from a municipal wastewater treatment plant on Maui and nearby coastal waters.

The researchers applied novel techniques including using aircraft to collect thermal infrared imagery to map oceanic inputs and the extent of effluent discharge, deployed scuba seafloor mapping, analyzed groundwater and algae samples to look for isotopic signatures unique to wastewater, used radioisotopes to help establish flow rates, and deployed tracer dyes to track rates and paths of the injected wastewater effluent to Maui’s coastal waters. The tracer dye test provided unequivocal evidence that the injected wastewater travels through groundwater to the coastal ocean.

“This was a very impactful scientific study with regard to protecting the environment, and with far-reaching socio-economic and sustainability implications for the State of Hawaiʻi and the nation as a whole. Our high-caliber UH team was glad that we could make it happen,” said Craig Glenn, lead author of the study and professor of Earth Sciences at SOEST.

The research team conclusively demonstrated that millions of gallons per day of deeply injected treated sewage effluent from the West Maui wastewater reclamation facility are being added to Maui’s adjacent ocean waters.

US Supreme Court Rules Against Maui In Major Clean Water Case

April 2020, Civil Beat, Gruber. WASHINGTON — The U.S. Supreme Court ruled Thursday that Maui County can’t skirt the Clean Water Act by merely pumping its sewage into groundwater before discharging it into the ocean.

In a 6-3 opinion written by Associate Justice Stephen Breyer, the majority ruled that Maui County, like other municipalities and businesses dumping pollutants into the nation’s rivers, lakes and oceans, must have a permit to do so.

The ruling is both a rebuke of Maui County and the Trump administration, which had joined the county in arguing that the Clean Water Act should only cover waste that was discharged directly into navigable waters, and not pollutants that were first filtered through groundwater before reaching their final destination.

Raise Your Hand: Honolulu Advertiser 2020/ Water In the Islands

(Editor Comment:  We commend high school senior Megan Okuma for her insightful article on water scarcity in the islands.)

By: Megan Okuma, Leilehua High School, Class of 2020.

As inhabitants of an island, most of Hawaii cannot fathom running out of water. However, although we are surrounded by such a precious resource, only 0.4% of the world’s water is drinkable. In Hawaii, most of our water comes from aquifers where it has traveled for years through soil and volcanic rock. This extensive, natural purifying system is the reason why Hawaii ranks first for water quality domestically. Yet with the population increasing and climate change affecting our rainfall patterns, Hawaii may see a decline of the cleanest water in the country within the next 100 years.

Conserving water is one of the easiest tasks in our environmental crisis to tackle as individuals because each of our actions directly affect the state of our water supply. We have complete control over the amount of water we use and if we take responsibility for this natural resource, we control the future of our water supply.

Water is not an infinite resource and, with a water cycle that has sustained Hawaii for ages, it makes more sense to change our habits rather than continue harvesting a finite resource with the same practices that created the problem in the first place. Of the 164 gallons of water used by residents every day, 100 gallons are used just for basic tasks: 20 to 50 gallons for showering, 18 to 24 gallons for flushing toilets and 26 gallons on running faucets. Through installing water- saving technology and routinely checking for leaks, the amount of water used can be reduced significantly.  Fortunately, there is an array of technology designed to combat the water crisis from focusing on bigger efforts like creating a new source of freshwater to simpler efforts like home instillations.

Our (Water) Project in Hawaii

December 2019 (LK: this is a fascinating article on water desal using solar power to begin to reforest an area on the Big Island) by Author Yishan Wong in Medium: In considering large-scale strategies to fix climate change, it turns out that the lowest-risk, lowest-cost, and most politically feasible strategy is the massive global reforestation of 3 billion acres.

To concretely prove out key technologies and costs, we have recently completed construction of the world’s largest fully off-grid 100% solar-powered desalination facility. There are other larger desalination plants, but they are all grid-tied and/or reliant at least partially on fossil fuels. In contrast, we are completely independent and 100% powered by solar energy.

Our facility comprises a half -acre of solar panels rated at roughly 128 kW total generating power and 300 kWh of battery storage. It is designed to produce 128,000 liters/day (34,000 gallons/day, or 128 m3/day) of freshwater, more than enough to irrigate the entire property. The facility is off the grid, so we have created our own electrical and water utility.

Recent cost improvements in solar mean that green desalination is now feasible. The significance of this cannot be understated, because desalination is uniquely suited to using solar power, as it avoids the solar intermittency issue.

The area of North Kohala where our project is located used to be covered with an ancient sandalwood forest, from the mountains to the shore. Hundreds of years ago, the entire forest was cut down to supply the profitable sandalwood trade and the region never recovered. It remains a desert to this day.

Mayor: Maui Will Not Withdraw Supreme Court Appeal in Lahaina Injection Well Case

(Editor Comment:  Environmentalists would like to settle this case out of court fearing that a more conservative Supreme Court will weaken the Federal Clean Water Act.)

October 2019: Maui Now: Wendy Osher: Maui Mayor Michael Victorino says the County of Maui will not withdraw its appeal of the Lahaina injection well case from consideration by the US Supreme Court.

He is now seeking clarification from the high court saying, “I want Maui County taxpayers and ratepayers to have their day before the US Supreme Court and get clarity on this important question on the application of the Clean Water Act.”

In a statement issued on Friday, Mayor Victorino said:

“To allow this to go unanswered leaves us vulnerable to more lawsuits, to uncertain regulatory requirements and staggering costs – all for what would be a negligible environmental benefit. The legal exposure is immense, not only for the County but for private property owners as well. It goes far beyond injection wells. The Ninth Circuit’s decision means that many County facilities – including Parks, Public Works, Environmental Management are likely in violation of the federal law as it’s interpreted by this court. Penalties can be imposed of nearly $55,000 per day per source. The effect on private property values, and the associated property taxes which fund the majority of County operations, cannot be ignored.”

Attached is Mayor Victorino’s letter to Maui County residents and a Corporation Counsel opinion on settlement authority. Letters, memorandums and other documents connected with the case can be found online.

Four community groups, represented by Earthjustice (Sierra Club and the Surfrider Foundation, with support from Hawai‘i Wildlife Fund and West Maui Preservation Association) filed a complaint with in Hawai‘i Federal District Court in 2012, alleging that Maui County was in violation of the Clean Water Act for its injection well discharges of municipal wastewater into the Pacific Ocean just offshore of Kahekili Beach Park in West Maui.

The groups claim that pollutants from the Lahaina Wastewater Reclamation Facility are flowing to the ocean and harming coral reefs.  Environmental groups who brought the lawsuit say they’re asking the County to fix nearshore deadzones and give Maui’s reefs a chance to recover.

State of Hawaii Freshwater Dashboard

October 2019  (Editor Comment:  According the State of Hawaii Dashboard, as of April 2019, the state estimated that we saved about 11 million gallons of water per day (gwd) of our target of 100 million gwd which we are aiming to hit by 2030.

  • We have used about 4 years of our 14 year timeline which is about 29% of our time period.
  • Ideally we would be hitting about 30 million gwd rather than 11 million gwd, which suggests we are slowly falling behind our target.

Is there any hope that we will actually achieve our 2030 water goal?  Regretfully climate change is making this an uphill battle.  But there is room for optimism.

  • The population increase is slowing on the islands and more and more low water appliances are being used by Hawaii households.
  • The increasing funds for watershed conservation and the implementation of stormwater utilities will also have a positive impact on replenishing our groundwater reserves.

The reuse of wastewater by businesses remains the speed bump in the road, smart regulations and increased incentives toward sustainability practices will help.

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.
