Aquifers Approaching Point of No Return

New studies warn that some of the world's largest aquifers may soon run dry, with no hope of ever filling again.
By: | July 1, 2015 • 2 min read

A new pair of studies show many of the largest aquifers are being depleted at alarming rates. Out of 37 of the world’s largest aquifers, more than 21 are past sustainability tipping points, which means that the rate of withdrawal exceeds the rate of replenishment.

Of those at highest risk, 13 are on the verge of exceeding the point at which they may not come back.

In a June 17 PBS NewsHour broadcast, Professor James S. Famiglietti of the University of California, Irvine, the lead author of one of those reports, discusses the potential impact of the dwindling supply of freshwater resources.

Famiglietti’s comments support those of experts interviewed for Aquifer: Nothing in the Bank, part of R&I’s April 2015 Emerging Risks special coverage. In the April article, experts discussed the deep impact of the depletion of California’s Central Valley aquifer on agriculture, as well as the ripple effects for real estate, construction, energy production and more.

2015 Most Dangerous Emerging Risks

Aquifer: Nothing in the Bank

Once we deplete our aquifers, there is nothing helping us get through extended droughts.

SCENARIO: Jon Gullo eyed the monitor as the nanobots burrowed underground, searching for moisture.

He and his lawyers had managed to convince regulators to let him explore the apparently empty aquifer under his 115 acres of almond trees in California’s Central Valley.

The nanobots were a last-ditch effort to find adequate water supplies in the face of a drought that was browning what had been the country’s richest agricultural zone.

Regulators were helping. Every other week, the U.S. Department of Agriculture collected data from satellites as they passed over the Western states. Like the nanobots, the satellites were searching, in vain mostly, for signs of water in the depleted aquifers, many of which had been pumped dry due to public and private sector mismanagement.

Now the chickens were coming home to roost. With the aquifers depleted, an economic sea-change was in the offing.

In the drought’s early years, businesses and governments invested billions in water recycling, desalination, and freshwater capture, storage and transport. They also drilled deeper and deeper into the aquifers, until stronger regulation of groundwater usage took effect. But the efforts couldn’t stop the aquifers, long a buffer against drought, from running dry.

Now the chickens were coming home to roost. With the aquifers depleted, an economic sea-change was in the offing.

Agriculture, one of the state’s biggest water users, was bearing the brunt of the shortage, and consumers paid for it at grocery stores and in restaurants. Although other areas of the world were ramping up production, fields were not producing fast enough to keep up, plus several batches of imported fruits and vegetables were found to contain traces of banned pesticides.

As the shortage continued, California’s politically powerful cities refused to take deeper cuts in their share of the remaining water supplies. And it was too costly in rural areas to pipe in water from desalination plants, or engage in the same aggressive recycling and conservation efforts used by larger metro centers.

Most of Gullo’s neighbors were already gone. His orchards were surrounded by fields of sand and dust, and abandoned food processing plants.

Undaunted, he was hoping to squeeze what he could from the depleted aquifers under his property.

The potential payoff was worth it, reasoned Gullo. Almonds were fetching astronomical prices thanks to production declines in the Central Valley, which had been the world’s leading grower.

Although he hesitated to admit it, he was frightened to try to sell his property. Few wanted to move to an area where jobs were disappearing and water was so scarce and expensive.

The dearth of homebuyers spurred by the water shortage resulted in a mini-foreclosure crisis up and down the Central Valley.

At least his county had oil and mining to fall back on, though automation and climate-change regulation had put dents in the workforce.

All newcomers could hope for were jobs in construction — fixing the damage to roads and bridges caused by the land subsidence that occurred after the aquifers ran dry.

But if there were no trucks ferrying crates of grapes, almonds and oranges, who needed roads?

ANALYSIS: As California’s drought wears on, no needles register precisely the decline of aquifers in the Central Valley, one of the country’s leading agricultural regions.

But water levels are clearly dropping. In some areas, the land has subsided more than a foot.

Ideally, the return of normal rainfall patterns will replenish the aquifers, though a full refill could take decades. However, the odds of even longer droughts — and even more strain on underground aquifers — are rising, according to climate scientists.

They cite the impact of global climate change, as well as the geological record. Medieval-era droughts in the American Southwest lasted 30 years or more.

Aquifers served as a buffer for those populations, which nonetheless succumbed to malnutrition and conflict, said B. Lynn Ingram, a professor of earth and planetary science at the University of California, Berkeley. That buffer is shrinking today.

“It’s kind of like the water in the bank that we’re using up now,” said Ingram, author of “The West Without Water.”

It’s not just a U.S. problem. Aquifers around the world are emptying, according to research by James Famiglietti, a professor of earth system science at the University of California, Irvine. Sao Paulo in Brazil, for example, has been hit hard, with the city experiencing widespread water shortages.

While modern economies are more technologically advanced, an extended drought and continued aquifer depletion would be painful, especially for agriculture.

The U.S. could see higher food prices and disruption to supply chains, according to insurance and agricultural experts.

The U.S. food supply is becoming more resilient, thanks to interest in local farms, said Dawn Thilmany, a professor of agricultural economics at Colorado State University.

But local farmers won’t be able to make up everything, and water scarcity may not be limited to California.

One alternative is crops genetically modified to withstand drought, experts said. More efficient water use is another. But as the globe warms, production may ultimately shift to northern states.

Imports from other countries also might make up the difference, but they bring new risks, especially if growers overseas are using pesticides or fungicides banned in the U.S., said Rodney Taylor, a managing director in the environmental services group for Aon Risk Solutions.

To guard against liability risks, food distributors and processors should scrutinize any new producers, said Tim McAuliffe, president of specialty casualty and programs for Ironshore. If crops shrink and prices rise, producers may be less rigorous about quality control.

New sources of surface water also pose a risk of contamination, as does water from deep inside an aquifer, he said. “I would call those a little more remote. But if the drought does continue at severe levels, it’s something that we would watch a lot closer.”

In California, urban areas could recycle wastewater and desalinate ocean water, said David Sedlak, a professor in the department of civil and environmental engineering at U.C., Berkeley. While costly, those efforts will keep the taps flowing.

“It’s just hard for me to imagine a situation where the cities run out of water,” said Sedlak.

Still, the shortage of water could have ripple effects. Electricity production, for example, may be stretched if dams are less productive and higher temperatures translate into greater demand.

“You could end up having situations where you have brownouts because there is so much strain,” said Kirsten Orwig, an atmospheric perils specialist for the reinsurer Swiss Re.

Risk managers will have to consider access to water when assessing supply chains and new operations, insurance executives said.

And if conditions stay dry, wildfires will worsen.

Interstate conflicts over water will flare, too, said David Bookbinder, a partner at Element VI Consulting, which focuses on climate change policy.

Aquifers and watersheds don’t follow state boundaries, he noted. The Supreme Court usually winds up arbitrating disputes over water.

“It’s problematic that our political structure is not set up to deal with this,” Bookbinder said. “That, I think, is going to be the biggest problem.”

Managing Chronic Pain Requires a Holistic Strategy

To manage chronic pain and get the best possible outcomes for the payer and the injured worker, employ a holistic, start-to-finish process.
By: | August 3, 2015 • 5 min read
IPS_BrandedContent

Chronic, intractable pain within workers’ compensation is a serious problem.

The National Center for Biotechnology Information, part of the National Institutes of Health, reports that when chronic pain occurs in the context of workers’ comp, greater clinical complexity is almost sure to follow.

At the same time, Workers’ Compensation Research Institute (WCRI) studies show that 75 percent of injured workers get opioids, but don’t get opioid management services. The result is an epidemic of debilitating addiction within the workers’ compensation landscape.

As CEO and founder of Integrated Prescription Solutions Inc. (IPS), Greg Todd understands how pain is a serious challenge for workers’ compensation-related medical care. Todd sees a related, and alarming, trend as well – the incidence rate for injured workers seeking permanent or partial disability because of chronic pain continues to rise.

Challenges aside, managing chronic pain so both the payer and the injured worker can get the best possible outcomes is doable, Todd said, but it requires a holistic, start-to-finish process.

Todd explained that there are several critical components to managing chronic pain, involving both prospective and retrospective solutions.

 

Prospective View: Fast, Early Action

IPS_BrandedContent“Having the wrong treatment protocol on day one can contribute significantly to bad outcomes with injured workers,” Todd said. “Referred to as outliers, many of these ’red flag’ cases never return to work.”

Best practice care begins with the use of evidence-based UR recommendations such as ODG. Using a proven pharmacological safety and monitoring opioid management program is a top priority, but needs to be combined with an evidence-based medical treatment and rehabilitative process-focused plan. That means coordinating every aspect of care, including programs such as quality network diagnostics, in-network physical therapy, appropriate durable medical equipment (DME) and in more severe cases work hardening, which uses work (real or simulated) as a treatment modality.

Todd emphasized working closely with the primary treating physician, getting the doctor on board as soon as possible with plans for proven programs such as opioid Safety and Monitoring, EB PT facilities, patient progress monitoring and return-to-work or modified work duty recommendations.

“It comes down to doing the right thing for the right reasons for the right injury at the right time. To manage chronic pain successfully – mitigating disability and maximizing return-to-work – you have to offer a comprehensive approach.”
— Greg Todd, CEO and founder, Integrated Prescription Solutions Inc. (IPS)

 

Alternative Pain Management Strategies

IPS_BrandedContentUnfortunately, pain management today is practically an automatic move to a narcotic approach, versus a non-invasive, non-narcotic option. To manage that scenario, IPS’ pain management is in line with ODG as the most effective, polymodal approach to treatment. That includes N-drug formularies, adherence to therapy regiment guidelines and inclusive of appropriate alternative physical modalities (electrotherapy, hot/cold therapy, massage, exercise and acupuncture) that may help the claimant mitigate the pain while maximizing their ongoing overall recovery plan.

IPS encourages physicians to consider the least narcotic and non-invasive approach to treatment first and then work up the ladder in strength – versus the other way around.

“You can’t expect that you can give someone Percocet or Oxycontin for two months and then tell them to try Tramadol with NSAIDS or a TENS unit to see which one worked better; it makes no sense,” Todd explained.

He added that in many cases, using a “bottom up” treatment strategy alone can help injured workers return to work in accordance with best practice guidelines. They won’t need to be weaned off a long-acting opioid, which many times they’re prohibited to use while on the job anyway.

 

Chronic Pain: An Elusive Condition

IPS_BrandedContentSoft tissue injuries – whether a tear, sprain or strain – end up with some level of chronic pain. Often, it turns out that it’s due to a vascular component to the pain – not the original cause of the pain resulting from the injury. For example, it can be due to collagen (scar tissue) build up and improper blood flow in the area, particularly in post-surgical cases.

“Pain exists even though the surgery was successful,” Todd said.

The challenge here is simply managing the pain while helping the claimant get back to work. Sometimes the systemic effect of oral opioid-based drugs prohibits the person from going to work by its highly addictive nature. In a 2014 report, “A Nation in Pain,” St. Louis-based Express Scripts found that nearly half of those who took opioid medications for more than a month in their first year of treatment then refilled their prescriptions for three years or longer. Many studies confirm that chronic opioid use has led to declining functionality with reduced ability to recover.

This can be challenging if certain pain killers are being used to manage the pain but are prohibitive in performing work duties. This is where topical compound prescriptions – controversial due to high cost and a lack of control – may be used. IPS works with a reputable, highly cost-effective network of compound prescription providers, with costs about 30-50 percent less than the traditional compound prescription

In particular compounded Non-Systemic Transdermal (NST) pain creams are proving to be an effective treatment for chronic pain syndromes. There is much that is poorly understood about this treatment modality with the science and outcomes now emerging.

 

Retrospective Strategies: Staying on Top of the Claim

IPS_BrandedContentIPS’ retrospective approach includes components such as periodic letters of medical necessity sent to the physician, peer-to-peer and pharmacological reviews when necessary, toxicology monitoring and reporting, and even addiction rehab programs specifically tailored toward injured workers.

Todd said that the most effective WC pharmacy benefit manager (PBM) provides much more than just drug benefits, but rather combines pharmacy benefits with a comprehensive ancillary suite of services in a single portal assisting all medical care from onset of injury to RTW. IPS puts the tools at the adjustor fingertips and automates initial recommendations as soon as the claim in entered into its system through dashboard alerts. Claimant scheduling and progress reporting is made available to clients 24/7/365.

“It comes down to doing the right thing for the right reasons for the right injury at the right time,” Todd said, “To manage chronic pain successfully – mitigating disability and maximizing return-to-work – you have to offer a comprehensive approach,” he said.
