Per- and polyfluoroalkyl substances (PFAS) are emerging groundwater contaminants which pose widespread risks to drinking water resources in Canada. Although the effects of PFAS on humans are currently a topic of debate, perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), namely the two most common PFAS, have been linked to various health problems such as increased blood cholesterol, liver damage, kidney and testicular cancer, and thyroid disfunction. Therefore, Health Canada has proposed drinking water screening values of 600 ng/L for PFOS and 200 ng/L for PFOA.****This project will investigate the removal of PFOS and PFOA using various adsorbent materials in order to develop an effective ex situ (i.e., pump and treat) groundwater treatment technology. We will screen a wide variety of materials, and select the most effective ones to further investigate factors affecting the adsorption of PFOS and PFOA onto the materials. The research will help our industry partner, InSitu Remediation Services Ltd. (St. George, ON) develop and design more efficient treatment systems, which will reduce treatment costs as well as exposure by human and biota to these potentially toxic contaminants.**

全氟烷基和多氟烷基物质（PFAS）是新出现的地下水污染物，对加拿大的饮用水资源构成广泛的风险。尽管全氟辛烷磺酸对人类的影响目前仍是一个争论的话题，但全氟辛烷磺酸（PFOS）和全氟辛酸（PFOA），即两种最常见的全氟辛烷磺酸，已与各种健康问题有关，如血液胆固醇增加，肝脏损伤，肾癌和睾丸癌以及甲状腺功能障碍。因此，加拿大卫生部建议饮用水全氟辛烷磺酸筛查值为600纳克/升，全氟辛酸筛查值为200纳克/升。本项目将研究使用各种吸附材料去除全氟辛烷磺酸和全氟辛酸，以开发有效的非原位（即，抽水和处理）地下水处理技术。我们将筛选各种各样的材料，并选择最有效的材料，以进一步研究影响材料吸附PFOS和PFOA的因素。这项研究将帮助我们的行业合作伙伴原位修复服务有限公司（圣乔治，ON）开发和设计更有效的处理系统，这将减少处理成本以及人类和生物群对这些潜在有毒污染物的暴露。
