Newell","doi":"10.1111/gwmr.12707","DOIUrl":"https://doi.org/10.1111/gwmr.12707","url":null,"abstract":"<p>While petroleum plumes and even many chlorinated solvent plumes stabilize in size on a time scale of a few to several years, perfluoroalkyl and polyfluoroalkyl substances, particularly perfluoroalkyl acids (PFAAs), in groundwater pose a specific challenge for site investigation and remediation due to their recalcitrance, which creates a potential for much longer-term plume expansion. Understanding the plume stability condition (i.e., is the plume expanding, stable, or shrinking) is essential for plume management and remedy selection, but resolving this trend using conventional monitoring methods can take 5 to 10 years or longer at many sites. This paper explores the difficulties in determining plume stability condition and presents four tools for evaluating stability condition more quickly and more efficiently: (1) high-resolution spatial sampling, (2) high-volume sampling, (3) passive integrative samplers, and (4) statistically based high-frequency sampling. By employing these tools, site managers can optimize monitoring strategies to quickly discern if and how much PFAA plume expansion is occurring and make timely informed decisions regarding PFAA plume management.</p>","PeriodicalId":55081,"journal":{"name":"Ground Water Monitoring and Remediation","volume":"45 1","pages":"68-79"},"PeriodicalIF":1.8,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kueper, Kent Novakowski","doi":"10.1111/gwmr.12696","DOIUrl":"https://doi.org/10.1111/gwmr.12696","url":null,"abstract":"<p>Thermal remediation of contaminated sites in fractured bedrock is complicated by the characterization and identification of heat transfer between fractures and matrix, and the complex interactions between the hydrogeological and thermodynamic parameters. A three-dimensional numerical model was applied to investigate these issues using global and local sensitivity analyses for the significance of six variables that potentially influence the heating performance in fractured rock. These variables include the radius and energy delivery strength of the heat source (which were used to study the scale effect and heating processes), the fracture aperture, fracture spacing, groundwater flow velocity, and the thermal conductivity of the rock matrix. A discrete Latin Hypercube-One-at-A-Time (LH-OAT) scheme is proposed and utilized as an experimental design and data analysis method for the discrete variables that apply to this case. The results show that at all four monitoring points within the heating area, the radius of the source and energy delivery strength are the most sensitive parameters. To minimize heat dissipation, additional heating wells are demonstrated to be effective for a small or pilot scale site (5 < <i>r</i> < 10 m), while the increase of energy delivery strength is more applicable for larger sites. Extra efforts should be invested to minimize heat dissipation when large fractures (2<i>b</i>> 1600 μm) are identified in the heating area. Re-samplings and re-evaluations with one-way perturbation in both positive and negative directions are thus suggested to avoid biased results caused by perturbations that occur in only positive or negative directions.</p>","PeriodicalId":55081,"journal":{"name":"Ground Water Monitoring and Remediation","volume":"45 1","pages":"55-67"},"PeriodicalIF":1.8,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gwmr.12696","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
