Trump’s EPA may weaken restrictions on disposal of oilfield wastewater — here’s what you need to know

Many Americans are aware that we are experiencing a major energy boom. But what many folks may not realize is that with this increase in oil and gas, also comes an increase in waste – specifically wastewater. In fact, for every barrel of oil produced wells can generate 10 times as much chemical-laden wastewater. All told, the industry produces over 900 billion gallons of wastewater a year, and we know very little about the chemicals in it.

Traditionally, companies have pumped this wastewater deep underground, but the growing volume is creating new challenges– leading many to wonder whether there may be different options for managing or reusing it. One of those options is treatment and discharge to rivers or streams.

Three things to know ahead of EPA’s oil and gas wastewater meeting

Tomorrow, the U.S. Environmental Protection Agency (EPA) will hold a special meeting to update the public about what the agency has learned since launching an examination into our nation’s current practices for handling wastewater from the oil and gas industry.

This research endeavor comes at a very salient time. The volume of wastewater generated by onshore oil and gas development is growing larger by the day – with production reaching nearly 900 billion gallons a year. This massive influx is forcing states, companies and other stakeholders to seriously think about whether our current methods for handling this wastewater are the best methods for the future based on a number of shifting dynamics.

The meeting tomorrow will allow agency officials to provide updates about what they’ve learned so far, and will give energy experts and other interested stakeholders the opportunity to weigh in with additional intel and perspectives. Here are three things to keep in mind ahead of tomorrow’s hearing. Read More »

State leaders concerned about safety of reusing oil and gas wastewater

Regulators from across the country met in Vermont this week at the Environmental Council of the State’s (ECOS) fall meeting to discuss some of the nation’s most pressing environmental challenges. I joined members of ECOS’ Shale Gas Caucus to discuss an emerging threat imminently impacting oil and gas-producing states: the question of what to do with the massive amount of wastewater produced by the oil and gas industry each year.

Why drinking water standards are the wrong standards for oil and gas wastewater

“It’s so clean I’d drink it.”

Travel to any recent conference or trade show on produced water management and there’s a good chance you’ll hear this line or something similar. I’ve heard it myself, alongside claims that a patented treatment delivers water that’s “fresh” or “meets drinking water standards.”

This sort of talk is on the rise as operators and regulators look for ways to reuse produced water both inside and outside of the oilfield. Some of these uses carry real risks to human health and the environment from chemicals that may be present—even after treatment. At first blush, if the product can be called “fresh” or meets drinking water standards, it doesn’t sound risky. So why the worry? The reality is that these statements tell us very little about the quality of treated produced water.

“Fresh” from a scientific perspective, means next to nothing. And drinking water standards are simply the wrong standards to apply to produced water, or for that matter any treated wastewater – industrial or municipal. Here’s why.

Getting dangerously creative with oil and gas wastewater

Look before you leap – why learning more about oilfield wastewater is critical to reducing health and safety risks.

The oil and gas industry has a massive wastewater problem. And if the growing dialogue about new ways of dealing with it are any indication, it may get worse if we aren’t careful.

Cost concerns, pressure to conserve water, and other factors have led some oil and gas companies to consider new ways to manage or repurpose wastewater – including using it to irrigate crops. That could create more problems than it solves.

Managing the massive amount of oil and gas wastewater has been a challenge for energy companies for generations. Some wells produce up to 10 times more wastewater than oil. In the United States, companies produce nearly 900 billion gallons of wastewater a year. That’s enough to fill over 1,000 football stadiums.

Ongoing Risks

Oil and gas wastewater is often many times saltier than sea water – and can ruin soil for generations if large amounts spill or leak during storage or transport.  In fact, landowners with a long history of oil and gas production on their lands know that a wastewater spill can cause much more long term damage to their land than an oil spill.

Report identifies ways to reduce water contamination from oil and gas development in Texas

A new report from the Academy of Medicine, Engineering and Science of Texas (TAMEST) is shedding more light on what we know and don’t know about the potential health and environmental impacts caused by oil and gas development in Texas.

The report, the first of-its-kind authored by experts across the state, looks at all areas of concern related to oil and gas – including seismicity, air pollution, land and traffic issues  – but TAMEST’s observations about the risks to water are especially noteworthy.
