Essays on Water Samples

In order to prevent the transmission of cryptosporidium to the public via public drinking water systems, various surveillance systems and regulations have been implemented hitherto, in order to increase the treatment of surface water supplies. Among these techniques is the molecular surveillance for the presences of cryptosporidium in water using PCR which resulted following the cryptosporidium outbreak in Milwaukee Wisconsin in 1993 (Johnson, et al., 1995). The outbreak resulted in effective systems being implemented to improve the quality of water treatment globally as Mac Kenzie, et al., (1994) observes. Guerrant, (1997) documents the onset of validation studies in Milwaukee ...

Lab 2 – Water Quality and Contamination

Abstract In this lab, the water quality, contamination, and treatment were investigated. The ability of contaminants (oil, vinegar, and laundry detergent) to remain in the water after passing through the ground was examined. Also, the simple filtering procedure was assessed for its effectivity in purifying water contaminated with soil. The quality of tap water, Fiji, and Dasani bottled waters by the content of ammonia, chlorides, iron, phosphates, total alkalinity, total chlorine, total hardness, and pH was analyzed and compared. All of the studied contaminants proved to remain in the volume of water after passing through the soil; the proposed ...

The objective of this experiment was to prepare Beer-Lambert calibration curves for different forms of nitrogen and to determine the concentration of nitrate, nitrite, and ammonia ions in different water samples from the Biscayne Bay.

Introduction

Nitrogen is the most abundant element in the Earth atmosphere. In is not surprising that it is one of the most crucial elements not only to human life but all life on our planet. The chemistry of nitrogen is rather diverse because it can exist in different oxidation levels – from +3 to -5. Due to its large impact on the biosphere, the circulation of ...
