Desalination Is enjoying Boom times as Cities Run out of Water

We’re running out of water. Is desalination the answer?

In California alone there are 11 desalination plants, with 10 more proposed. But there are big downsides to making seawater drinkable.

A reverse-osmosis desalination plant.

On a Friday this spring, a group of students from Yale University’s School of Forestry and Environmental Studies drove two hours to visit Swansea, Mass., a community with rolling green hills on the commonwealth’s southern coast, for a surprising reason — to see the town’s newest water treatment facility.

They were greeted by Robert Marquis, who’s been Swansea’s water manager for four decades.

“So you’re standing in the first publicly held desalination facility in the Northeast,” Marquis told the students.

Desalination is the process of making freshwater out of saltwater by removing the salt. People have been doing it on a small scale for centuries. On a big scale, though, desalination of seawater takes a lot of energy and a lot of money. But as water becomes more scarce and more contaminated, some communities feel like they don’t have a choice.

Jakarta’s Giant Seawall Is Useless if the City Keeps Sinking

Late last week, president Joko Widodo of Indonesia told the AP that he’s fast-tracking a decade-in-the-making plan for a giant seawall around Jakarta, a city that’s sinking as much as 8 inches a year in places—and as seas rise, no less. Models predict that by 2050, a third of the city could be submerged. It’s an urban existential crisis the likes of which the modern world has never seen.

Latest solar distillation gadget concept claims near-perfect efficiency in purifying water

The new water purification technique involves draping a sheet of carbon-dipped paper in an upside-down “V”

Access to clean water is one of the world’s most pressing problems, but a team of University at Buffalo researchers has come up with a new take on an old technology that uses sunlight to purify water. Led by associate professor of electrical engineering Qiaoqiang Gan, the team has created a device that uses black, carbon-dipped paper to produce fresh water with what is claimed to be near-perfect efficiency.

Earth is “drinking” more seawater through the Mariana Trench than previously thought

Seismic activity at the Mariana plate is dragging far more water into the Earth’s mantle than previously thought(Credit: Yarr65/Depositphotos)

The Earth’s surface is famously a pretty wet place, but a new study suggests that the mantle is home to much more water than was previously believed. Observations of seismic activity around the Mariana Trench have revealed that subducting tectonic plates are dragging more water deeper into the Earth, which could change our understanding of the global water cycle.

Fighting a losing battle with the elements

A row of a dozen houses perched on cliffs at Sidmouth in east Devon are losing their yard space to the sea.

Martin McInerney, 82, has lost 20m (65ft) of his garden in the 20 years he has lived there and expects the cliff to be at his back door within 60 years.

The Environment Agency says it is working to get funding for a plan to reduce encroachment by the sea.

Tahoe refutes allegations in reports of water contamination

Tahoe Resources (TSX, NYSE:THO) is denying a media report issued on Thursday that its Shahuindo mine in Peru has contaminated local water supplies.

The story (in Spanish) by Cajabamba Peru, stated that heavy rains caused a leaching pit to overflow and flooded a nearby village.

“The heavy rains that have occurred that in the early hours of today, one of the waste pits of this company overflowed and flooded the village of Liclipampa Bajo, in the province of Cajabamba, leaving crops and houses flooded with highly toxic materials,” states the article, translated from Spanish. “The population is worried because in this pond there would be highly dangerous waste, which would put at risk the lives of the affected inhabitants.”

However according a release by Tahoe issued the next day, a ditch designed to keep rainwater out of the mining area overflowed, but it was upstream of the permitted discharge point. “At no time has the rainwater had any contact with process water or any contamination from industrial activities,” the Vancouver-based gold producer stated. It added that the Agency for Environmental Assessment and Control (OEFA) visited the mine to take water and sediment samples, and found that the leach pond did not overflow.

Tahoe did acknowledge that some communities were impacted by the heavy rains and that it is moving heavy equipment in to clear roads and mud.

The Shahuindo mine is an open-pit heap leach gold mine that started commercial production in 2016. It expects to ramp up to full production of 36,000 tonnes per day in the second half of this year. The mine has proven and probable reserves of 110.3 million tonnes, containing 1.9 million gold ounces, with an average grade of 0.52 grams per tonne.

Bad health news for surfers

SURFERS are three times more likely to have dangerous superbugs in their bodies than non-surfers.

For the first time, international researchers have discovered that wave riders have a higher rate of the bacteria E coli in their gut that does not respond to the antibiotic cefotaxime.

Cefotaxime has previously been prescribed to kill off these bugs but some have acquired genes that enable them to survive.

E coli is caused by food or water contamination and can spark bloody diarrhoea, nausea, vomiting and fever.

The resport published in the journal Environment International found that boardriders ingest 10 times more water than swimmers.

As superbugs continue to be a global challenge, there is increasing focus on the part played by the natural environment. This research was carried out in the UK.

“We are not seeking to discourage people from spending time in the sea – an activity which has a lot of benefits in terms of exercise, wellbeing and connecting with nature,” Dr Will Gaze, head researcher from University of Exeter Medical School, said.

“It is important that people understand the risks involved so that they can make informed decisions about their bathing and sporting habits.

“We now hope that our results will help policymakers, beach managers and water companies to make evidence-based decisions to improve water quality even further for the benefit of public health.”

Queensland environmental expert Professor Tor Hundloe said our seas were cleaner than many surfing spots overseas.

“Certainly tests upstream may show up bacteria but once you reach the open waters, they are relatively clean,” Prof Hundloe said.

“I would surf anywhere on this planet. There’s not much of a risk from contaminated water,” Kayla said.
