The Puquios System of Nazca

The arid Nazca region of Peru is dotted with spiral-shaped indentations, part of an irrigation system that helped indigenous civilizations thrive here before European contact. Although the region’s rainfall varies year-to-year, it never amounts to much. So pre-Columbian Nazcans turned instead to underground aquifers to gather and transport water.

Aquifers in the region slope downward, following the local geology. Puquios builders began by digging a preliminary well in the highlands, tunneling down until they reached the aquifer. Then they built a horizontal tunnel underground, sloping gently downward, toward the location where water was needed. Along that roughly horizontal tunnel, they built additional chimneys, the spiraling mouths of which are seen above. These chimneys are thought to serve multiple purposes. They provide maintenance access to the aqueduct tunnel, and their shape may help funnel wind underground to oxygenate the water and help keep it flowing. Eventually, the underground tunnel would exit into an open trench and a reservoir, providing year-round water for irrigation and personal use.

Although the puquios cannot themselves be dated through usual archaeological means, the current consensus is that they originate from around 500 C.E., with subsequent modifications by both indigenous and colonial inhabitants. Impressively, several dozen puquios are still providing water today. (Image credits: Ab5602/Wikimedia, PsamatheM/Wikimedia, and R. Lasaponara et al.; research credit: R.

#CoalMining Devastated the #Water and Brought #BlackLungDisease -- #ForestLake Hearing on #Coal

June 6, 2025

"On Friday, May 30, 2025, the Office of the Speaker held a public hearing on coal at the Forest Lake Chapter House in Forest Lake (Tsiiyi’ Be’ak’id), Arizona. This open forum allowed participants to share their input and comments regarding the Federal Executive Order 14241, “Reinvigorating America’s Beautiful Clean Coal Industry,” aimed at amending federal policies to boost the #CoalIndustry.
This public hearing came after community opposition and frustration to Navajo Nation President #BuuNygren ’s support of President #Trump’s executive orders to prop up coal. The public hearing generated over 50 public comments, more than 169 people in attendance.

"Tó Nizhóní Ání executive director #NicoleHorseherder was one of the first to provide comments in opposition of coal siting the decades-long impacts on the land and water. “The bottom line is coal mining has had adverse impacts to the aquifers and that’s Navajo water. What is Navajo going to do about it?' said Nicole as she provided a brief overview of the coal mining and reclamation issues at the #KayentaMine.

"The federal agencies responsible for overseeing reclamation and cleanup acknowledged, verbally, that their duties are to the shallow #aquifers impacted by coal but mentioned the deep aquifers are the responsibility of the Department of Interior. These are just one of many issues impacting the #BlackMesa region, which played host to the coal industry for over 50 years."

Hydraulic head (Hydrology 💧)

Hydraulic head or piezometric head is a measurement related to liquid pressure and the liquid elevation above a vertical datum. It is usually measured as an equivalent liquid surface elevation, expressed in units of length, at the entrance of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well, and given infor...

Groundwater in the Arctic is delivering more carbon into the ocean than was previously known

A relatively small amount of #groundwater trickling through #Alaska's #tundra is releasing huge quantities of #carbon into the #ocean, where it can contribute to #ClimateChange, according to new research out of The University of Texas at Austin.
As the tundra continues to thaw and the flow of submarine groundwater ratchets up, Demir said that the outflow of carbon from shore to sea could effectively make ocean surface waters a carbon source to the #atmosphere. The #CO2 released via groundwater could also contribute to ocean #acidification.
"The #Arctic coast is changing in front of our eyes," said Bayani Cardenas, a co-author of this study and professor at the Jackson School's Department of Earth and Planetary Sciences. "As #permafrost thaws, it turns into coastal and submarine #aquifers. Even without this thawing, our studies are among the first to directly show the existence of such aquifers."

From 2015 through 2023, #satellite measurements showed that the average amount of #freshwater stored on land—that includes liquid surface water like lakes and rivers, plus water in #aquifers underground—was 290 cubic miles (1,200 cubic km) lower than the average levels from 2002 through 2014, said Matthew Rodell, one of the study authors and a hydrologist at #NASA's Goddard Space Flight Center in Greenbelt, Maryland. "That's two and a half times the volume of Lake Erie lost."

after #ElNiño subsided, global freshwater failed to rebound. In fact, Rodell and team report that 13 of the world's 30 most intense droughts observed by GRACE occurred since January 2015. Rodell and colleagues suspect that #globalwarming might be contributing to the enduring freshwater depletion.

Infiltration (hydrology) (Hydrology 💧)

Infiltration is the process by which water on the ground surface enters the soil. It is commonly used in both hydrology and soil sciences. The infiltration capacity is defined as the maximum rate of infiltration. It is most often measured in meters per day but can also be measured in other units of distance over time if necessary. The infiltration ca...

The system that moves #water around the #Earth is off balance for the first time in human history

The #WaterCycle refers to the complex system by which water moves around the Earth.

By Laura Paddison, CNN
Published Oct 17, 2024

"Humanity has thrown the global water cycle off balance 'for the first time in human history,' fueling a growing water disaster that will wreak havoc on economies, #FoodProduction and lives, according to a landmark new report.

"Decades of destructive #LandUse and #WaterMismanagement have collided with the human-caused #ClimateCrisis to put 'unprecedented stress' on the global water cycle, said the report published Wednesday by the Global Commission on the Economics of Water, a group of international leaders and experts.

"The water cycle refers to the complex system by which water moves around the Earth. Water evaporates from the ground — including from lakes, rivers and plants — and rises into the atmosphere, forming large rivers of water vapor able to travel long distances, before cooling, condensing and eventually falling back to the ground as rain or snow.

"Disruptions to the water cycle are already causing suffering. Nearly 3 billion people face #WaterScarcity. #Crops are shriveling and cities are sinking as the groundwater beneath them dries out.

"The consequences will be even more catastrophic without urgent action. The water crisis threatens more than 50% of global food production and risks shaving an average of 8% off countries’ GDPs by 2050, with much higher losses of up to 15% projected in low-income countries, the report found.

'“For the first time in human history, we are pushing the global water cycle out of balance,' said Johan Rockström, co-chair of the Global Commission on the Economics of Water and a report author. '#Precipitation, the source of all #freshwater, can no longer be relied upon.'

"The report differentiates between '#BlueWater,' the liquid water in #lakes, #rivers and #aquifers, and '#GreenWater,' the moisture stored in #soils and #plants.

"While the supply of green water has long been overlooked, it is just as important to the water cycle, the report says, as it returns to the atmosphere when plants release water vapor, generating about half of all rainfall over land.

"Disruptions to the water cycle are 'deeply intertwined' with climate change, the report found.

"A stable supply of green water is vital for supporting vegetation that can store planet-heating #carbon. But the damage humans inflict, including destroying #wetlands and tearing down #forests, is depleting these carbon sinks and accelerating #GlobalWarming. In turn, climate change-fueled heat is drying out landscapes, reducing moisture and increasing [#wildfire] risk.

"The crisis is made more urgent by the huge need for water. The report calculates that, on average, people need a minimum of about 4,000 liters (just over 1,000 gallons) a day to lead a 'dignified life,' far above the 50 to 100 liters the United Nations says is needed for basic needs, and more than most regions will be able to provide from local sources.

"Richard Allan, a climate science professor at Reading University, England, said the report 'paints a grim picture of human-caused disruption to the global water cycle, the most precious natural resource that ultimately sustains our livelihoods.'

"Human activities 'are altering the fabric of our land and the air above which is warming the climate, intensifying both wet and dry extremes, and sending wind and rainfall patterns out of kilter,' added Allan, who was not involved in the report.

"The crisis can only be addressed through better management of natural resources and massive cuts in planet-heating pollution, he told CNN.
"The report’s authors say world governments must recognize the water cycle as a '#CommonGood' and address it collectively. Countries are dependent on each other, not only through lakes and rivers that span borders, but also because of water in the atmosphere, which can travel huge distances — meaning decisions made in one country can disrupt rainfall in another.

"The report calls for a 'fundamental regearing of where water sits in economies,' including better pricing to discourage wastefulness and the tendency to plant water-thirsty crops and facilities, such as #DataCenters, in water-stressed regions."

Not the first time #Israel has used #DepletedUranium on civilian populations...

From 2015: VP/HR — Gaza Strip and bombs with depleted uranium

March 3, 2015

"There is now enough convincing data to prove that Israel has repeatedly used depleted uranium [#DU] weaponry. Such was the case in the large-scale massacre that took place in the #GazaStrip in August 2014.

"These weapons cause #cancers and #foetal malformations in the populations affected, which may take on epidemic proportions. In #Iraq, in the city of #Fallujah, where these bombs were launched in industrial quantities by the International Coalition led by the# UnitedStates, 52% of children today are born with #deformities.

"The lethal effects of #radioactivity caused by explosions and subsequent fires, including cancer of the lungs and pleura, can persist for centuries in the #environment and particularly in #aquifers. We are therefore on the verge of another humanitarian catastrophe in #Palestine and in particular in the #Gaza Strip, where thousands of tons of depleted uranium bombs were dropped with the effects that have already been documented.

"In view of this situation, what is the Vice-President/High Representative thinking of doing to pressure Israel into assuming its responsibilities for this crime against humanity, and what help can the Vice-President/High Representative offer to the Palestinian authorities to carry out epidemiological monitoring, which also includes all EU citizens who have moved to the territory since then?"
