Review of Phosphorus Control Measures in the United States and Their Effects on Water Quality

Fast Detection of Different Water Contaminants by Raman Spectroscopy and Surface-Enhanced Raman Spectroscopy

“…The Raman spectrum of KH 2 PO 4 in crystalline form is shown in Figure 4 . The spectral reference structure for the detection of the anion PO 4 3− is at about 915 cm −1 , assigned to the ν1 (νP–OH) vibration mode of the ion [ 58 , 59 ].…”

Exploring the Impacts of Full-Scale Distribution System Orthophosphate Corrosion Control Implementation on the Microbial Ecology of Hydrologically Connected Urban Streams

“…Certain Cyanobacteria are known to have the functional trait for the high affinity phosphate uptake system, called the “phosphate-specific transport system” ( 50 ). However, many of these functional traits are only induced under low phosphate concentration conditions, which these streams were not since they were above the 1986 EPA recommendation of 0.1 mg/L ( 51 ). Collectively between the five urban streams studied, Cyanobacteria had an average relative abundance of 0.87% ± 1.1% before PO 4 3– addition into the DS, and 0.65% ± 0.62% after PO 4 3– addition.…”

Simulation of flow and eutrophication in the central Salem River, New Jersey

“…Accordingly, two management scenarios were developed to reduce symptoms and effects of eutrophication in the Salem River by constraining the availability of nutrients from nonpoint sources along with upgrades in treatment at the Woodstown WWTP. The scenarios were developed in coordination with NJDEP, and other studies (for example, Wood and Rounds, 1998;Litke, 1999;Omni Environmental, 2007) were consulted regarding design and analysis for evaluating the effect of reduced nutrient loads on eutrophication. The model was first used to predict water quality under predevelopment conditions in order to identify stream reaches that might not attain water quality targets under natural conditions.…”
