Fracking Creates Water Scarcity Issues in Michigan
Concerns about the impact to local groundwater by massive water use—on a scale never before seen in Michigan fracking operations—are coming to a head, as the plan for Encana Oil & Gas (USA) Inc. to use 8.4 million gallons of water to fracture a single well has been stymied by a lack of water on site.
Instead, the company is trucking water—nearly 1 million gallons of it in just one week—from the City of Kalkaska’s water system to meet its needs. This one fracking operation today is using more water than Kalkaska is using for all its needs over the same time period.
The Westerman 1-29 HD1 gas/oil well, located on Wood Road in Rapid River Township, Kalkaska County, originally permitted to Chevron Michigan, LLC, is now being operated by Encana.
The permit issued by the Michigan Department of Environmental Quality (DEQ) authorized one water well on the site. The estimated water required for the gas/oil well was 8.4 million gallons. That compares to about 10,000 gallons used to complete or “stimulate” wells in the traditional way—a massive increase in consumptive water use by the fracking industry compared to the past.
The Michigan Water Assessment Withdrawal Tool (WWAT) estimated that 900 gallons per minute could be removed safely from the site and would cause no adverse resource impact. As it turns out, there isn’t enough water available on the site to provide 900 gallons per minute, let alone be safely removed.
An additional eight water wells were drilled on the site but apparently they did not produce either. Starting on May 31, water began being removed from the Kalkaska municipal water system to frack the gas/oil well.
The municipal withdrawal did not come close to supplying the water necessary to complete the Westerman well, so on Saturday, another water well was drilled off site in the surrounding field.
That water well also failed to produce sufficient water and trucks running around the clock continued to haul more than 900,000 gallons of water from the Kalkaska municipal system over the weekend. At last report on June 4, the water was still being trucked to the well site from the municipal water supply.
“If the citizens of Michigan knew corporations were destroying hundreds of millions of gallons of Michigan water—water that is supposedly protected by government for use by all of us—they would be opposing this new kind of completion technique," stated Paul Brady, a local resident and leading contributor of respectmyplanet.org. "These deep shale unconventional wells are using massive amounts of water without adequate testing and solid data on aquifer capacity.”
Brady noted that the new fracking methods permanently remove water from Michigan’s watersheds. It is polluted with chemicals, shoved deep into the ground and never returned to the water cycle. Encana has stated in shareholder presentations that up to 500 wells are planned for Michigan. Five new wells were permitted in Excelsior Township last week that estimate using 152,000,000 gallons of water. Eight more permit applications are pending.
The water use for these types of wells in Michigan is unprecedented. There is no gas or oil play in the U.S. that is using this much water per well.
The Michigan DEQ has taken some steps recently to try and deal with the astounding amounts of water destroyed by modern fracking. But as of today, the primary tools that they are using to determine the adverse impact to our water are inadequate to even judge how much water is available in any given location (as demonstrated by the Westerman well situation), never mind how much can be safely removed. Michigan has no groundwater maps of this area; state officials don’t know how much water withdrawal our aquifers in Kalkaska County can support.
However, there is a way to find this out: Do a pump aquifer yield test. State officials should require this testing whenever withdrawals of this magnitude are proposed for any reason, not just oil and gas exploration.
“This is not about the gas and oil industry,” says Brady. “We wholeheartedly support the Michigan oil and gas worker: They are our neighbors, family and friends here in Kalkaska. We are confident local oil and gas workers value the water as much as we do.”
Elected officials often remind us that water is by far our most precious resource. They need to step in and ensure that such massive quantities are not misused in this manner, and that unsustainable well drilling is not allowed.

Farms with just one or a handful of different crops encourage fewer species of pollinating and pest-controlling insects to linger, ultimately winnowing away crop yields, according to a new study.
Up to half of the detrimental impacts of the "landscape simplification" that monocropping entails come as a result of a diminished mix of ecosystem service-providing insects, a team of scientists reported Oct. 16 in the journal Science Advances.

"Our study shows that biodiversity is essential to ensure the provision of ecosystem services and to maintain a high and stable agricultural production," Matteo Dainese, the study's lead author and a biologist at Eurac Research in Bolzano, Italy, said in a statement.
It stands to reason that, with declines in the sheer numbers of insects that ferry pollen from plant to plant and keep crop-eating pests under control, these services will wane as well. But until now, it hasn't been clear how monocultures affect the number and mix of these species or how crop yields might change as a result.
Aiming to solve these questions, Dainese and his colleagues pulled together data from 89 studies cutting across a variety of landscapes, from the tropics of Asia and Africa to the higher latitudes of northern Europe. They tabulated the number of pollinating and pest-controlling insects at these sites — both the absolute number of individuals and the number of species — along with an assessment of the ecosystem services the insects provided.
In almost all of the studies they looked at, the team found that a more diverse pool of these species translated into more pollination and greater pest control. They also showed that simplified landscapes supported fewer species of service-providing insects, which ultimately led to lower crop yields.
The researchers also looked at a third measure of the makeup of insect populations — what they called "evenness." In natural ecosystems, a handful of dominant species with many more individuals typically live alongside a higher number of rarer species. The team found as landscapes became less diverse, dominant species numbers dwindled and rare species gained ground. This resulting, more equitable mix led to less pollination (though it didn't end up affecting pest control).
"Our study provides strong empirical support for the potential benefits of new pathways to sustainable agriculture that aim to reconcile the protection of biodiversity and the production of food for increasing human populations," Ingolf Steffan-Dewenter, one of the study's authors and an animal ecologist at the University of Würzburg in Germany, said in the statement.
The scientists figure that the richness of pollinator species explains around a third of the harmful impacts of less diverse landscapes, while the richness of pest-controlling species accounts for about half of the same measure. In their view, the results of their research point to the need to protect biodiversity on and around crops in an uncertain future.
"Under future conditions with ongoing global change and more frequent extreme climate events, the value of farmland biodiversity ensuring resilience against environmental disturbances will become even more important," Steffan-Dewenter said.

Greenland had quite the summer. It rose from peaceful obscurity to global headliner as ice melted so swiftly and massively that many were left grasping for adjectives. Then, Greenland's profile was further boosted, albeit not to its delight, when President Trump expressed interest in buying it, only to be summarily dismissed by the Danish prime minister.
During that time I happened to be in East Greenland, both as an observer of the stark effects of climate change and as a witness to local dialogue about presidential real estate aspirations, polar bear migrations and Greenland's sudden emergence as a trending topic.

Creepy-crawlies are among the oldest life forms on this planet. Before dinosaurs ever walked the earth, insects were certainly already there. Some estimates date their origins to 400 million years ago. They're also extremely successful. Of the 7 to 8 million species documented on Earth, around three quarters are likely bugs.
But several insect species could disappear for good in the next few decades and that would have serious consequences for humans.
