Abstract
Four years ago this month, I published an editorial in Integrated Environmental Assessment and Management (IEAM) titled “The Modern Era of Environmental Regulation” (Toll, 2020), a synopsis of the first 50 years of the modern era. It applauded improvements in environmental quality achieved by regulating chemical pollution, but it criticized the environmental regulatory framework and the profession that had developed to serve it. My concern was that environmental regulations provided the motive, means, and opportunity to spend too much time and money on relatively minor problems.
That concern hasn't ebbed. I've become both more cynical and more pragmatic. I've come to appreciate the importance of trust. Risk aversion creates mistrust, making smaller problems more difficult to solve than bigger ones. If you find yourself working on a site where the risk or potential risk reduction is relatively low, beware: Such sites can be more difficult to close. Stakeholders often mistrust experts who tell them that a site is not badly polluted, especially if remediation might be a gateway to restoration or redevelopment opportunities.
My pragmatic side recognizes that people, by and large, are rational actors.
If behaviors seem irrational, then we should suspect that we misunderstand what motivates those behaviors. As environmental scientists and engineers, we are trained to collect and analyze data to gradually reveal the truth of a matter. That's fine up to a point, but the logic breaks down when we buy into the belief that environmental data and their analyses hold the answers to environmental problems. We overvalue data on environmental conditions and undervalue data on human values and motivations. This fundamental misconception leads to misunderstandings, which lead to frustration. Frustration makes us vulnerable to being drawn into what, in my 2020 editorial, I called the “regulatory-industrial complex.” The “regulatory-industrial complex” rewards people for enabling and indulging risk aversion because, frankly, fearmongering pays and most of us need paychecks. In the United States alone, we're spending billions of dollars (USD) to remediate (and litigate) contaminated sites, with little evidence that these investments are paying off in reduced risk. Were I to indulge my cynicism, I might say that these expenditures are meant to fund careers rather than mitigate risk.
This problem is on track to get worse before it gets better. Remedial investigations at contaminated sites in the United States generally focus on Toxic and Priority Pollutants. The Toxic Chemicals list is found at 40 Code of Federal Regulations (CFR) Part 401, §401.15 (https://www.ecfr.gov/current/title-40/chapter-I/subchapter-N/part-401/section-401.15) and the Priority Pollutants list is found in Appendix A to 40 CFR Part 423 (https://www.ecfr.gov/current/title-40/chapter-I/subchapter-N/part-423/appendix-Appendix%20A%20to%20Part%20423). Both lists specify chemicals regulated in the United States for which we have developed analytical test methods. Note that the Toxic and Priority Pollutants that we study in contaminated site investigations generally do not include contaminants of emerging concern (CECs). CECs comprise chemicals that are widely used (e.g., pharmaceuticals and personal care products) and chemicals that were in widespread use until recently, like polyfluorinated alkyl substances (PFAS). Ling's (2024) recent paper can be seen as support for the “worse before it gets better” assertion. The author reports that “current costs to remove and destroy the total PFAS mass released annually into the environment would likely exceed the global gross domestic product of 106 trillion USD.” Thus, remediation, which is already cost prohibitive, could get a lot more expensive unless we find cheaper, better solutions to pollution problems.
Less emphasis on chemical exposure, and more emphasis on whether and how chemicals affect ecosystem services and function, would be a step in the right direction. Unfortunately, we have installed institutional barriers that make it difficult to change course. I learned this in the 1990s. At the time, I was working on various projects tasked with helping plan 30-year combined sewer overflow (CSO) control programs. My team conducted technical studies that focused on chemical and pathogen fate and effects. One site stands out in my memory, because of the stakeholder involvement process.

期刊介绍:
Integrated Environmental Assessment and Management (IEAM) publishes the science underpinning environmental decision making and problem solving. Papers submitted to IEAM must link science and technical innovations to vexing regional or global environmental issues in one or more of the following core areas:
Science-informed regulation, policy, and decision making
Health and ecological risk and impact assessment
Restoration and management of damaged ecosystems
Sustaining ecosystems
Managing large-scale environmental change
Papers published in these broad fields of study are connected by an array of interdisciplinary engineering, management, and scientific themes, which collectively reflect the interconnectedness of the scientific, social, and environmental challenges facing our modern global society:
Methods for environmental quality assessment; forecasting across a number of ecosystem uses and challenges (systems-based, cost-benefit, ecosystem services, etc.); measuring or predicting ecosystem change and adaptation
Approaches that connect policy and management tools; harmonize national and international environmental regulation; merge human well-being with ecological management; develop and sustain the function of ecosystems; conceptualize, model and apply concepts of spatial and regional sustainability
Assessment and management frameworks that incorporate conservation, life cycle, restoration, and sustainability; considerations for climate-induced adaptation, change and consequences, and vulnerability
Environmental management applications using risk-based approaches; considerations for protecting and fostering biodiversity, as well as enhancement or protection of ecosystem services and resiliency.
