For those with sites in different regulatory jurisdictions, one challenge is addressing how the requirements or expectations for VI investigation and mitigation differ from one jurisdiction to the next. The overall lack of consensus can make it difficult to manage sites in a consistent manner between jurisdictions. This paper takes into account VI guidance, petroleum hydrocarbon-specific VI guidance, and/or media-specific volatilization criteria found in broader regulatory programs. This is an update of the author's previous reviews published in 2007, 2012, and 2018. Since our most recent update, 30 states have revised their guidance, issued new guidance or updated criteria or other VI-related information. For each State and the District of Columbia, the review includes tabulations of the available types of screening values (e.g., soil, groundwater, soil gas, and indoor air), the screening values for selected chemicals that commonly drive VI investigations (e.g., trichloroethylene [TCE], tetrachloroethylene [PCE], benzene, and other selected volatile organic compounds [VOCs]), and the basis of risk levels used for cancer and non-cancer risk. Federal values are also included for comparison. In addition, we summarize available key policy criteria for each state including: trigger distances, default subsurface to indoor air attenuation factors, policies for evaluation of petroleum VI, strategies for preferential pathways, and policies for mitigation of VI. The details presented in this paper provide a useful technical reference and regulatory summary for practitioners and the regulated community nationwide.</p>","PeriodicalId":55081,"journal":{"name":"Ground Water Monitoring and Remediation","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gwmr.12627","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139765815","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}

However, the volatility of these gases makes it challenging to avoid excessive losses during sampling. The objective of this study was to compare the quantification of acetylene, ethene, and ethane using passive vapor diffusion (PVD) samplers vs. conventional low-flow groundwater collection. Samples were obtained from 8 to 13 monitoring wells at three sites that show potential for biotic and abiotic degradation of TCE in fractured rock aquifers. Method reporting limits (MRLs) for the PVD samplers were 0.25 μg/L for acetylene (0.0094 μM) and 0.28 μg/L for ethene and ethane (0.0099 and 0.0092 μM, respectively); the MRLs for conventional low-flow groundwater samples were ~40% higher. For two of the sites, the maximum concentrations of acetylene, ethene, and ethane obtained with the PVD samplers were comparable to the conventional low-flow samples. The frequency of detection for these gases with the PVD samplers was also comparable to conventional low-flow groundwater sampling. For one of the sites with higher levels of acetylene (maximum of 13 μg/L), the concentrations from the PVD samplers were approximately twofold higher than those with conventional low-flow groundwater sampling. Based on robust detection of acetylene, ethene, and/or ethane, it appears likely that degradation of TCE is occurring at the three sites that were sampled. The use of PVD samplers can reduce the possibility of false negative results to provide another line of evidence in support of natural attenuation.</p>","PeriodicalId":55081,"journal":{"name":"Ground Water Monitoring and Remediation","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139765816","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}
