SACRAMENTO, Calif - A new report says hydraulic fracturing can contaminate groundwater when the excess water is not properly disposed of, but is not linked to earthquakes in California.

In January, a study by the Seismological Society of America linked a series of earthquakes in Ohio to fracking, and there have been similar claims in other states as well.

The new study released Thursday comes from the California Council on Science and Technology and the Lawrence Berkeley National Laboratory. Jane Long, the lead scientific researcher, says hydraulic fracturing poses some safety concerns but they're manageable.

"A lot of things people were concerned about are things that are not as big a problem as they think they are," says Long. "And some of the practices are things that need to change and need more attention."

The report says the oil companies should phase out percolation ponds used to dispose of excess water because toxic fracking chemicals can get into the aquifer. And it recommends companies put aside about a third of the chemicals currently in use because there's not enough data about them.

The Center for Biological Diversity points to the finding that oil operations can pollute the air in their immediate vicinity. Long is optimistic that the report will spur further reforms.

"Some of them are going to be recommendations that will be very easy to act on right away and I think they will be acted on and some of them are going to require some process," she says.

The report was required by the 2013 passage of State Senate Bill 4, which established new safety measures for fracking, rules that went into effect on July 1.

The arrival of fall has farmers transitioning to the harvest season, but what if some gathered their crops with rows of solar panels right alongside them?

Minnesota is part of such emerging projects. The agrivoltaics scene is carving out pathways for utilities and developers to reduce carbon emissions by adding more solar farms, while allowing emerging farmers, who face land-access issues, to grow fruits and vegetables on the same property.

Brian Ross, vice president of renewable energy for the Great Plains Institute, said it is a great example of two worlds working to benefit each other.

"We're all working together to kind of take that example of local food production and try to expand it out. How can we actually put this at scale?" Ross asked. "How can we do it within the context of existing solar-development parameters?"

As they track the effectiveness of smaller projects, Ross noted they need to figure out certain logistics, such as the ideal height of the solar panels. Other partners say irrigation is another puzzle to solve. The Minnesota project involves Connexus Energy, U.S. Solar and Big River Farms. On a solar site just outside the Twin Cities, aspiring farmers are testing adding horticultural vegetation.

Sophia Lenarz-Coy, executive director of The Food Group and Big River Farms, said the pilot initiative can especially help historically disadvantaged farmers.

"Farmers of color, women farmers, folks who have a harder time accessing capital," Lenarz-Coy pointed out. "This is one of the biggest barriers that we see is wanting long-term land access but maybe not having the capital to purchase land."

She added farmers often end up signing leases for property but it makes it harder to grow their operations under short-term contracts. The solar site provides hope in establishing more certainty for producers and the vision they have for their food-growing venture.

Project leaders say another thing they hope to learn is the difference between crops grown underneath and around solar arrays versus crops grown in the open.

A new report finds more than half of the sewage facilities in Idaho had pollution violations in 2022.

The sixth annual analysis by the Idaho Conservation League says 57% of the state's wastewater treatment plants discharged harmful substances last year.

Will Tiedemann, conservation associate with the Idaho Conservation League, said the report focuses on facilities that had the potential to cause the most harm - such as those releasing wastewater in sensitive habitats.

He said size has had an impact on those violations in recent years.

"There's quite a few facilities that are a little smaller and they do deal with outdated equipment," said Tiedemann, "either failed, you know, or were built 20, 30, 40 years ago."

Collectively, there were 520 violations of the Clean Water Act by Idaho wastewater treatment plants in 2022. The report focuses on three facilities that accounted for a quarter of the violations in Driggs, Jerome and Kuna.

Tiedemann noted that there are some positives in this report. Facilities in 51 cities and towns reported no discharge violations.

Others made significant improvements from 2021 to 2022 - including those in Blackfoot, Marsing and Wilder.

"This isn't an insurmountable issue," said Tiedemann, "that numerous examples of facilities who have dealt with issues and have made the investments and put in the resources and the time and the hard work to address this issue. So we definitely commend those facilities."

Tiedemann said having the means to curtail violations can be a major issue, especially for smaller towns. But he said federal resources are available, including through COVID-19 relief funds.

Amid the United Auto Workers strike, some advocates argued it is time to implement clean car standards.

Gary Schlack, a city council member in Allen Park, supports the UAW workers in their quest for contracts aligning with their skills, dedication, and loyalty. He said the state's automakers are committed to increasing the production of zero-emission vehicles in the next decade, and intend to leverage the Infrastructure Investment and Jobs Act to do so.

"It's time for Ford, GM, and Chrysler's parent company Stellantis to come to the table," Schlack asserted. "EV vehicles and with these EPA standards put in place these workers are concerned that these jobs if they go nonunion competitive wages will fall."

The energy department predicts EV battery manufacturing will support 10 to 13 million fully electric vehicles annually by 2030. Michigan, Georgia, Kentucky, Kansas, North Carolina, Ohio, and Tennessee are key players in the growth, fueling job opportunities across the sector.

Alex Cornell du Houx, president and co-founder of Elected Officials to Protect America, stressed addressing pollution in the transportation sector is crucial to enhancing national security, and mitigating the climate crisis.

"We need to export our oil and import actually dirty oil for use in the United States," du Houx pointed out. "We are still dependent on OPEC, which is a(n) association of dictators. They're not democratic nations. So it puts us at a vulnerability."

Transportation generates more greenhouse gasses than any other sector of the U.S. economy, making up 27% of total emissions and 45% of all U.S. oil consumption.
