“Despite how the health of nature drives the health of the economy, implementation of the national economic accounts is disconnected from our understanding of nature.” — Excerpt from the White House’s draft strategy on natural capital accounting.
By the Numbers
$10.3 Billion to $31.3 Billion: Estimated cost of replacing the benefits of four dams on the lower Snake River, if the dams were to be breached. That’s according to a report from the offices of Gov. Jay Inslee and Sen. Patty Murray, both Democrats from Washington state, where the dams have blocked salmon runs for decades. The report states that replacing the dams’ benefits — irrigation, hydropower, navigation, and recreation — is possible but at significant cost.
Accounting for Nature
The White House is requesting information that would help administration staff standardize methods for valuing, measuring, and tracking the benefits that the natural world provides to humans.
Called natural capital, these benefits range from the water-filtering capability of wetlands to the flower pollination conducted by bees. The natural capital accounts would stand next to producer-consumer measurements like gross domestic product as part of official U.S. economic statistics.
Along with the information request, the White House published a draft strategy for natural capital accounting.
Officials might consider a report published in July from an intergovernmental panel on ecosystems and biodiversity. The IPBES report found more than 50 accounting methods for nature’s value, many of which go beyond the concept of natural capital.

Proposal Would Bring Two PFAS Under Superfund Umbrella
The EPA proposed designating two “forever chemicals” — PFOA and PFOS — as hazardous substances under the federal Superfund law, a move that would provide a pathway for forcing cleanup of the chemicals and recovering the cost of doing so.
The action applies to five broad categories of industries, including wastewater utilities. The other categories are all PFAS producers, processors, or companies that make products containing PFAS.
The lobby group for the wastewater industry has appealed to Congress for an exemption from Superfund liability. Its argument is that wastewater utilities do not produce the contaminants. They are merely conduits, and ratepayers should not be saddled with cleanup costs.
Environmental advocates, meanwhile, are calling for the EPA to designate the entire class of PFAS – thousands of chemical compounds in total – as hazardous substances.
The agency will soon publish a notice of its proposal in the Federal Register, which will open a 60-day public comment period.
Studies and Reports
PFAS Drinking Water Standards: A Science Review
The EPA Science Advisory Board submitted its final report assessing the agency’s scientific justifications for setting national drinking water standards for PFOA and PFOS.
The board supported many of the agency’s conclusions. But John Gardella, a lawyer who follows PFAS cases, noted that the board issued some red flags: a “lack of transparency, flawed data, inconsistent methodologies, and potentially unsound scientific foundations for some conclusions.”
The EPA plans to propose draft regulations for the two chemicals this fall and will incorporate the board’s findings.
Green Infrastructure Outcomes in the Great Lakes
How good is green?
A U.S. Geological Survey research team summarized the existing literature on the performance and hindrances of green infrastructure projects in the Great Lakes basin.
The number of such designs in the region is rapidly increasing though accounting for its benefits is incomplete and “poorly supported by empirical evidence,” the report noted.
Many projects aim to dampen urban flooding or trap contaminants. Many projects did so. However, there are always drawbacks. One of the biggest unintended consequences, the report found, is the potential for unwanted contaminants in stormwater to mix with local groundwater.
The report assessed outcomes from mostly leafy interventions: street swales, green roofs, urban trees, and porous pavement. It did not examine rainwater harvesting or detention basins.
On the Radar
Rio Grande Water Dispute Approaches Deadline
At a virtual hearing last week, the Supreme Court-appointed judge who is overseeing a Rio Grande water dispute ordered the parties to share draft settlement language by the end of next week, El Paso Matters reports.
The basin states have a September 23 deadline to produce an agreement or the case would move to trial before the nation’s high court.
“We continue to make progress,” said Lee Leininger of the U.S. Department of Justice, which is party to the lawsuit. “There’s choppy waters, but we are continuing the course.”
Texas sued New Mexico in 2013, claiming that groundwater extraction in New Mexico was siphoning water meant for Texas under the Rio Grande Compact, a water-sharing agreement signed in 1938.
