Monitoring And Mitigation Of Per- And Polyfluoroalkyl Substances (Pfas) In Urban Stormwater Runoff, Mustafizur Rahaman

Theses and Dissertations

Per- and polyfluoroalkyl substances (PFAS) are emerging contaminants known for their persistence with widespread environmental and health concerns. Urban stormwater runoff could be a non-point pollution source that transports PFAS to receiving water bodies. This study analyzed types and concentrations of PFAS in stormwater runoff from Trenton and Glassboro, New Jersey, with samples collected from high- and low-traffic areas during precipitation events in February, June, July, and August 2024. Significantly higher concentrations of PFAS were identified in high-traffic areas than low-traffic areas (p< 0.05) in both cities for most sampling events, confirming the role of traffic in PFAS dispersal. To address PFAS contamination in stormwater runoff, this study evaluated the removal of six U.S. Environmental Protection Agency (USEPA)-regulated PFAS compounds from synthetic stormwater runoff using aluminum-based water treatment residuals (Al-WTRs, by-products of the drinking water treatment process). The findings demonstrated that Al-WTRs exhibited high sorption capacities and low desorption rates for PFAS, particularly for long-chain PFAS compounds such as perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), supporting their potential as an economical and effective sorbent for stormwater PFAS management. Furthermore, the durability and sustained performance of Al-WTRs indicated their feasibility for future field-scale applications.

Egyptian Public Economic Policies Between The Supreme Constitutional Court And The State, Dina Sherif Abdelrahman

Theses and Dissertations

To fully understand the present, it is useful to trace the past. The relationship between the rule of law and economic development has been a significant topic in the literature. In the 1960s, it was believed that economic development required regulated markets in which the state played an active role. However, when it became evident that the state's involvement in the economy yielded few of the promised benefits, economic neoliberalism emerged. This involved the state withdrawing from the economy and allowing the market to take the lead. Still, the state must govern the institutional conditions necessary for the markets. These …

Unraveling The Relationship Between Sexual Shame And Father-Child Sex Communication, Hannah Mireya Brundage

Theses and Dissertations

This study sought to understand the relationship between father’s sexual shame and children’s sexual shame. Parents play a role in shaping their children’s behaviors and perceptions in regard to sexuality.
