The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is to improve the quality of well water for drinking. As of 2019, 43 million Americans do not have access to public water and rely on private sources. Unlike public water systems, private wells are not regulated, placing these Americans at an increased health risk from waterborne contaminants. This lack of access results in socioeconomic health disparities. Treating odorous water and other organic and biological contaminants requires multiple treatment systems that add significant complexity and costs. This project will develop a new water treatment system that simultaneously treats odorous water, recalcitrant organics (e.g., pharmaceuticals), and biological pathogens without the addition of chemicals.The proposed project will advance the understanding of inhibiting agents in photocatalytic water treatment systems. Understanding these fouling mechanisms is critical to developing a robust photocatalyst for water treatment. This project will identify the primary photocatalyst inhibitors in groundwater sources and determine the mechanism for their inhibition, e.g., bulk quenching or surface fouling. Analytical techniques to study the binding between fouling agents and photocatalyst surfaces include several surface-sensitive spectroscopy methods, such as nano-Fourier transform infrared spectroscopy (nano-FTIR) and tip-enhanced Raman spectroscopy (TERS).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这种创新合作伙伴关系的更广泛的影响/商业潜力 - 技术翻译（PFI -TT）项目是提高饮酒井的质量。截至2019年，有4,300万美国人无法获得公共水，并依靠私人资源。与公共供水系统不同，私人井不受监管，使这些美国人面临着污染物的健康风险。缺乏访问导致社会经济健康差异。处理有气味的水和其他有机和生物污染物需要多种治疗系统，以增加大量的复杂性和成本。该项目将开发一种新的水处理系统，该系统同时处理有可能的水，顽固的有机物（例如药物）和生物病原体，而无需添加化学物质。拟议的项目将促进对光催化水处理系统中抑制剂的理解。理解这些结垢机制对于开发出可靠的水处理光催化剂至关重要。该项目将确定地下水源中的主要光催化剂抑制剂，并确定其抑制作用的机制，例如散装淬火或表面结垢。研究结垢剂和光催化剂表面之间的结合的分析技术包括几种表面敏感的光谱法，例如纳米象形转换红外光谱谱（Nano-ftir）（Nano-ftir）和尖端增强的拉曼光谱镜检查（TER）。审查标准。
