the National Drinking Water Quality Standards (NDWQS) in 1983‚ with the most recent revision in 2000 due for circulation for use in 2002. The standards stipulate limits for physical‚ chemical‚ microbiological and radiological parameters and compliance with these standards is mandatory for all private water suppliers. Supporting documentation is available to ensure effective implementation of the standards and include information on the National Programmed for Drinking Water Quality Surveillance‚

15 Problem: Can water float on water? Introduction: Can water float on water some say ye because ice can float but we are talking about water on top of water. The salt water and fresh will have different effects on the experiment. The experiment also see if the warmer the water is the different way it look. Purpose: The reason that I am doing this project is to see if water can float on water and to see the water at different densities‚ and salinity. To see if the salt water would sit on the

Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water molecules

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things
