Access to safe water is a basic human right recognized by the United Nations General Assembly in 2010 (WHO, 2020). However, a least 2.2 billion people globally still are without safely managed water services meaning they use a drinking water source that can be contaminated with faeces (WHO, 2020). With such a pressing global health issue, it is clear that improvement to water systems is important and required in the Agenda 2030 Sustainable Development Goals (SDGs). However, to improve water systems and prove they are safe water sources, water quality testing must occur. A solution to this issue is the …
Removal Of Nitrates From Stormwater Using Nanoclays, Rubia Siddiqi
Removal Of Nitrates From Stormwater Using Nanoclays, Rubia Siddiqi
Master's Theses
Creeks and rivers are often polluted as a result of stormwater runoff that carries various contaminants in to open water bodies, causing adverse environmental and health effects. Low impact development (LID) techniques are currently employed to treat this runoff prior to discharge. Nitrate, however, is not consistently removed by these LID techniques. This study analyzed the ability of several nanoclays to remove nitrate in runoff and determined the feasibility of using them as a soil supplement for LID implementation. Six different nanoclays and HCl-treated clays were compared (pre-modified trimethyl stearyl ammonium nanoclay, pre-modified dimethyl dialkyl amine nanoclay, unmodified hydrophilic bentonite, …
Pervious Pavement Systems For High Traffic Roadways, Kevin M. Smith
Pervious Pavement Systems For High Traffic Roadways, Kevin M. Smith
Construction Management
This report highlights the benefits and detriments of pervious pavement systems through research of existing knowledge and multifaceted experiments to determine the feasibility of implementing a pervious pavement system on high traffic roadways. With over 40,000 miles of highway in the United States alone and severe water crises in states like California and growing environmental and safety concerns, the need for pervious pavements is abundantly clear. The research conducted utilizes existing knowledge on pervious pavements and applies it to the application of high traffic roadways. The experiment tests four different pervious concrete mix designs to determine compressive strength and water …
