Recent legislative actions in several Republican-led states are reshaping environmental regulation frameworks, sparking concern among health experts. These new laws impose stringent limits on state agencies’ abilities to establish environmental standards, potentially elevating public health risks, including cancer, according to scientific warnings.
The U.S. Chamber of Commerce, supported by various business trade groups, has championed a “Sound Science” bill. This legislation has been enacted in Alabama and Tennessee, with similar proposals under consideration in Utah and Kentucky.
These bills mandate that environmental regulations be based on the “best available science,” drawing inspiration from a previous executive order by former President Donald Trump. The legislation prevents state agencies from imposing stricter standards than federal guidelines or regulating contaminants unless a “direct causal link” to health harm is established.
However, experts argue that proving direct causation between contaminants and diseases is complex. Jeffrey Wickliffe, a professor at the University of Alabama at Birmingham, highlights that pinpointing a specific contaminant as the cause of a disease is nearly impossible. “It’s going to be a standard that’s very difficult to ever meet,” Wickliffe remarked.
Wickliffe noted that while asbestos exposure is a rare case where direct causation can be established due to its link to mesothelioma, most diseases have multiple potential causes. Toxicology studies typically involve assessing large population data, which might show a correlation rather than direct causation.
Despite repeated inquiries, the U.S. Chamber of Commerce has not addressed the scientific community’s concerns. Mark Behrens, representing the Chamber, defended the legislation as “common-sense” during an Alabama Senate hearing, emphasizing reliance on credible scientific evidence, aligning with Trump’s executive order.
Challenges to Scientific Research
Critics argue the bill marginalizes key areas of scientific research. In Alabama, Utah, and Kentucky, bills proposed in 2026 prohibit regulations based solely on increased disease risk, a clause absent in Tennessee’s law.
Wickliffe, alongside 44 other scientists and health professionals, opposed the Alabama bill, deeming the proof requirements “insurmountable” compared to standard scientific practices. The opposition letter questioned if smoking or lead exposure could meet the bill’s criteria.
“Regulations are based on risk so that we protect humans from getting sick in the first place,” the letter argued, emphasizing the protection of vulnerable populations.
Despite opposition, the Alabama bill passed predominantly along party lines, with some Republicans dissenting over potential unintended outcomes. Governor Kay Ivey signed it into law without additional remarks.
Sarah Stokes from the Southern Environmental Law Center criticized the law for regressing Alabama’s pollution protection efforts, noting that proving “actual bodily harm” is now a prerequisite for agency action.
Impact on Water Quality Standards in Alabama
Alabama’s legislation includes a clause that prevents agencies from defaulting to or mandating the use of the U.S. Environmental Protection Agency’s Integrated Risk Information System (IRIS) for water quality criteria.
This move appears to counter a previous Alabama Environmental Management Commission decision to align state water standards with the IRIS database. The Alabama Department of Environmental Management has not commented on the new law’s potential impacts.
According to the new law, agencies that utilized the IRIS database must revise their standards within nine months of the act’s effective date.
Support for the bill also came from state trade groups like Manufacture Alabama and the Business Council of Alabama. Jon Barganier of Manufacture Alabama advocated for the legislation, asserting it balances scientific and regulatory needs while fostering economic stability.
Stokes suggested that industry influences shaped the bill’s provisions, arguing it allows continued high-level pollution under the guise of economic development.
