Summary
Soil sorption technologies can immobilize harmful per- and polyfluoroalkyl substances (PFAS) found at military sites. This approach prevents PFAS contamination of groundwater and drinking water sources, offering a promising environmental remediation solution.
Area of Science:
- Environmental Science
- Environmental Engineering
- Geochemistry
Background:
- Military bases and nearby communities face significant per- and polyfluoroalkyl substances (PFAS) contamination.
- Aqueous Film-Forming Foams (AFFFs) are a primary source of this widespread PFAS pollution.
- Contaminated soil poses a risk to groundwater and drinking water supplies.
Purpose of the Study:
- To review and identify the most effective soil sorption technologies for PFAS remediation.
- To assess the potential of soil sorption for immobilizing PFAS in contaminated environments.
- To provide a resource for addressing PFAS contamination from military sources.
Main Methods:
- Collaborative review of existing scientific literature and technological assessments.
- Evaluation of various soil sorption mechanisms and materials for PFAS capture.
- Analysis of technology performance data and feasibility studies.
Main Results:
- Soil sorption technologies demonstrate significant promise for immobilizing PFAS.
- These technologies can effectively prevent the migration of PFAS from soil to water.
- The review identified several leading technologies for practical application.
Conclusions:
- Soil sorption is a viable strategy for mitigating PFAS contamination at military installations.
- Further research and implementation of these technologies are crucial for protecting water resources.
- Collaboration between research institutions and regulatory bodies accelerates the adoption of effective solutions.

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).

27.2K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

14.1K
Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?
