The Fate Of Nitrogen And Phosphorus From A Simulated Highway Cross-Section, Zuzanna Wasowska Jan 2014

The Fate Of Nitrogen And Phosphorus From A Simulated Highway Cross-Section, Zuzanna Wasowska

Electronic Theses and Dissertations

Nutrient pollution as a result of excessive fertilizer application is of major concern for Florida's water resources. Excess fertilizer can be lost either via surface runoff or by leaching through the soil mass eventually reaching water bodies and leading to eutrophication. The focus of this study is to analyze the effect of low rainfall intensities and overland flow from an adjacent roadway surface on the loss of nutrients from two different fertilizers. This study focuses on the fate of the nitrogen and phosphorus present in fertilizers utilized by the Florida Department of Transportation for the stabilization of highway embankments. This …


The Effectiveness Of Specifically Designed Filter Media To Reduce Nitrate And Orthophosphate In Stormwater Runoff, Mikhal Moberg Jan 2008

The Effectiveness Of Specifically Designed Filter Media To Reduce Nitrate And Orthophosphate In Stormwater Runoff, Mikhal Moberg

Electronic Theses and Dissertations

Throughout Central Florida surface water and ground water are decreasing in quantity and quality in part because of excess Nitrate and Phosphorus nutrients. Stormwater runoff serves as a medium for transport of Nitrate and Phosphorus to surface water and ground water. The goal of this experiment is assess the Nitrate and Phosphorus removal in stormwater using select media. The results of a literature search, batch test experimentation and column test experimentation are used to determine an optimal media blend that may be implemented in detention ponds to reduce Nitrate and Phosphorus. The extensive literature search revealed 32 different media that …


A Kinetics Study Of Selected Filtration Media For Nutrient Removal At Various Temperatures, Elizabeth Henderson Jan 2008

A Kinetics Study Of Selected Filtration Media For Nutrient Removal At Various Temperatures, Elizabeth Henderson

Electronic Theses and Dissertations

In recent years the nutrient levels of the Upper Floridan aquifer have been increasing (USGS, 2008). An example of this is found in Ocala, Florida where Silver Springs nitrate concentrations have risen from 0.5 mg/L in the 1960 s to approximately 1.0 mg/L in 2003 (Phelps, 2004). Because stormwater is a contributor to surficial and groundwater aquifer recharge, there is an increasing need for methods that decrease nitrogen and phosphorus levels. A laboratory column study was conducted to simulate a retention pond with saturated soil conditions. The objectives of the column studies reported in this thesis were to investigate the …
