2 ABSTRACT Ground water is the biggest source of drinking water available to human population around the world and is rapidly being polluted because of industrialization and increasing demands of agriculture around the world. A set of simple experiments were done to find out what kind of changes do some of these contaminants cause in ground water. Samples of tap water and bottled water were also analyzed for safety. Chemicals like oil, vinegar and soap cause turbidity, odor and color change in water samples. Tap water is much safer to drink than bottled water because it contains less contamination than bottles water. INTRODUCTION Ground water is the water that is present below the surface in rocks and can become contaminated by both natural and human activities. Chemicals such as soap and detergents, fertilizers and pesticides, pharmaceutical by-products are introduced into our water systems on a daily basis. These products enter into the soil and get dissolved in the ground water. Different ingredients react differently once they reach the underground water; either from gravity naturally carrying them or by the downward movement of rain water. Both organic and inorganic substances may contaminate the ground water with heavy metals like Nickel, Cadmium, and Chromium etc… (Christensen et al, 2001). The wastes from the pharmaceutical’s that end up in the water have been known to cause cancer. (Krifa et al. 2013). Many of the active ingredients in the pharmaceutically chemicals make it to the groundwater sources untreated which then causes water contamination. (Herber, 2002). Global warming can be contributed the burning of fossil fuel which results in an abundance of carbon dioxide being released into the atmosphere and it also changes the chemical makeup of rain water. Water is a universal solvent; however, its

WATER QUALITY LAB OUTLINE 2 ABSTRACT Ground water is the biggest source of drinking water available to human population around the world and is rapidly being polluted because of industrialization and increasing demands of agriculture around the world. A set of simple experiments were done to find out what kind of changes do some of these contaminants cause in ground water. Samples of tap water and bottled water were also analyzed for safety. Chemicals like oil, vinegar and soap cause turbidity, odor and color change in water samples. Tap water is just as safe to drink as bottled water because the contamination levels are fairly equal. INTRODUCTION Ground water is present below the surface in porous rocks and is susceptible to contamination by natural and especially human related activities. Large amounts of chemicals like soap and detergents, fertilizers and pesticides, pharmaceutical by-products are discharged in to fresh water aquifers every day. These contaminants leach in to the soil and dissolve in ground water. Different contaminants have different rates of solubility and degradation once they reach the underground water table either by simple flow or by the downward movement of rain water. The ground water may become contaminated with both organic and inorganic substances especially heavy metals like Cadmium, Chromium and Nickel, etc. (Christensen et al, 2001). Pharmaceutical wastes can cause cancer in human cells. (Krifa et al. 2013). Many pharmaceutically active chemicals reach groundwater sources almost untreated and cause contamination. (Herber, 2002). Increase in the emissions of carbon dioxide by burning fossil fuels is the single largest cause of environmental degradation resulting not only in global warming but also causing acid rain which alters the pH of ground water. Water is a universal
