Polyfluoroalkyl substances (PFAS) seem to be in every aspect of our modern-day life. PFAS chemicals manufactured by DuPont and 3M are found in our food wrappers, pots, pans, firefighting foam, and anything nonstick. The abundance of these chemicals raises concerns about the contamination of our drinking water sources. Since these chemicals get washed up by rainwater runoff, they ultimately end up in our groundwater sources. Once in our groundwater, the PFAS-contaminated water gets pumped up by wells utilized for our drinking water. In this project, our team looked at the contamination of these chemicals in our local community. Our team collaborated with local officials to gain access to sample the Garner C well, the Twin Springs well, a local private well in our community, and the Palmyrita treatment plant, where we measured both the influent and effluent water. Our team then conducted tests on each water sample to determine the amount of perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), perfluorobutanoic acid (PFBA), perfluorohexane sulfonate (PFHxS), perfluorononanoic acid (PFNA), perfluoroheptanoic acid (PFHpA), and perfluorodecanoic acid (PFDA) in each of our samples using Environmental Protection Agency (EPA) 533 rules and procedures. Using the tests from the Palmyrita treatment plant, we determined how effective Riverside's treatment process is for removing PFAs across its water. This paper is intended to inform individuals how to test and sample for PFAS from their local wells and educate readers on PFAS contamination in the Riverside Municipal area. This study aims to quantify PFAS levels in Riverside Wells and evaluate the effectiveness of local water treatment processes, especially activated carbon filtration.
多氟烷基物质（PFAS）似乎存在于我们现代生活的方方面面。杜邦公司和3M公司生产的PFAS化学物质存在于我们的食品包装、锅碗瓢盆、消防泡沫以及任何不粘物品中。这些化学物质的大量存在引发了人们对饮用水源污染的担忧。由于这些化学物质会被雨水径流冲刷，最终会进入我们的地下水源。一旦进入地下水，受PFAS污染的水会通过用于饮用水的水井被抽取上来。在这个项目中，我们的团队研究了当地社区这些化学物质的污染情况。我们的团队与当地官员合作，获取了加纳C井、双泉井、我们社区的一口当地私人井以及帕尔米里塔处理厂的样本，在那里我们测量了进水和出水。然后，我们的团队对每个水样进行测试，以使用美国环境保护局（EPA）533规则和程序确定每个样本中全氟辛酸（PFOA）、全氟辛烷磺酸（PFOS）、全氟丁酸（PFBA）、全氟己烷磺酸（PFHxS）、全氟壬酸（PFNA）、全氟庚酸（PFHpA）和全氟癸酸（PFDA）的含量。通过帕尔米里塔处理厂的测试，我们确定了河滨市的处理过程在去除水中PFAS方面的效果如何。本文旨在告知个人如何从当地水井中检测和采样PFAS，并教育读者了解河滨市地区的PFAS污染情况。本研究旨在量化河滨市水井中的PFAS水平，并评估当地水处理过程的有效性，特别是活性炭过滤的有效性。
