Water Quality and Contamination
Abstract
In this experiment water quality and contamination of groundwater were investigated. First, I will observe the effects that many pollutants have on groundwater. I predict that in this experiment the oil and vinegar will create the largest quality of contamination to the water, while the laundry detergent will just create a bad smell to it. Considering the smells and thickness to these ingredients I think that it will cause the water quality to have a bad smell and cause the water to be very cloudy. Once filtering the contaminated water, the water will be clear and purified. Second, I will experiment water treatment and filtering. I predict that once the contaminated water is treated and filtered that it will leave me with little or no contamination in it. Then for the last experiment, I will determine the difference between bottled water and tap water to discover any contamination. I predict that the tap water will be the most contaminated and with the most chemicals in it, while the bottled waters; Dasani and Fiji will be completely filtered and free of any chemicals. Introduction

There were three different steps to this investigation to determine the final hypothesis. The first experiment was the effects of groundwater contamination, second was water treatment and third was drinking water quality. There are a variety of portable sampling devices available for the collection of groundwater, however, each application has different requirements and is dependent on the contaminants. A number of different sampling devices and their applicability are used to determine the contamination. Techniques for the preservation and analysis of samples and quality assurance and quality control are also presented. WATER QUALITY 3

The objective of groundwater sampling is to determine whether or not the quality
