The end product is an updated version of BioPIC, a successful, existing decision framework for MNA of chlorinated ethenes. In evaluating MNA, the goal is to follow existing protocols but also incorporate more recent insights that have increased the potential viability of this technology for a wider number of contaminants. This includes data supporting the first line of evidence for MNA (decreasing concentration trends over time at appropriate sampling locations), as well as data that will serve as secondary and tertiary lines of evidence for MNA. For the BioPIC update, a similar lines of evidence approach was developed, using information from literature and project‐specific data to identify the relevant lines of evidence. As part of the update, a model for predicting contaminant trends over time and distance, including a method to estimate site‐specific biodegradation rate constants for chlorinated ethenes, chlorinated ethanes, and 1,4‐dioxane, has been included within BioPIC. The quantitative software tool provides step‐by‐step technical guidance for collecting and evaluating other lines of evidence, including data associated with targeted 14C assays, isotope fractionation, biomarkers for degradation, geochemical parameters, and co‐contaminant concentrations, to improve the MNA evaluation process.","PeriodicalId":158105,"journal":{"name":"Groundwater Monitoring & Remediation","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120784916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies have shown that passive samplers can produce accurate results under well‐controlled steady concentration conditions, and field performance was also demonstrated at several sites. The objective of this study was to examine passive sampler performance in settings with time‐varying indoor air concentrations, through a comparison of passive sampler results to concentrations determined by 24‐h active sorbent tube sampling in a series of multi‐week deployments. Sampling was performed in a well‐instrumented residential building as well as industrial buildings, over periods of time ranging from 1 to 7 weeks. Strong linear correlations were noted between passive and active sampling concentration results for some passive samplers, with passive sampling results being similar to or lower than measured active sampling results by about 50% for those samplers in the residential study and about 25% higher in the industrial building study. Other samplers produced poor agreement. The conclusion from this study is that some passive samplers have great potential for use in multi‐week indoor air quality monitoring. It was further determined that there is need for accepted procedures to validate and calibrate passive samplers for use in the field.","PeriodicalId":158105,"journal":{"name":"Groundwater Monitoring & Remediation","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120074960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
