    Faster Dissolved Oxygen Test Kit Purpose The purpose of my project is to determine if there is any significant difference in dissolved oxygen (DO) levels as measured by the traditional HACH (R) method or the newly developed CHEMets (R) test kit under typical field conditions. Hypothesis My hypothesis is that there is no significant difference in dissolved oxygen (DO) levels as measured by the traditional HACH (R) method or the newly developed CHEMets (R) test kit under typical field conditions. ...
  • Water Quality Carbon Dioxide
    842 words
    Water quality is a complex term to evaluate. The health of a water ecosystem depends on so many things. These parameters are each intertwined and connected. For simplicity there are several mainstream parameters that are used in conjunction with each other to determine the water s quality. These include: alkalinity, ammonia content, carbon dioxide, chlorine, nitrates, dissolved oxygen, phosphates, temperature, and turbidity. The most visible sign of poor water quality remains to be animal popul...
  • Phosphates And Dissolved Oxygen
    829 words
    Phosphates are present in many natural waters, such as lakes and streams. Phosphates are essential to aquatic plant growth, but too much phosphate can lead to the growth of algae and results in an algae bloom. Too much algae can cause a decrease in the amount in dissolved oxygen in the water. Oxygen in water is affected in many different ways by phosphates Phosphorus is usually present in natural waters as phosphate (Mc welsh and Raintree, 1998). Phosphates are present in fertilizers and laundry...
  • Test Tube Water Color Turbidity

    Introduction During lab on Monday, April 9, 2002 our class conducted a lab on water chemistry and pollution. The two bodies of water that were choose as samples where, the Wall pond and the HGTC pond. Each group had to test the water for Temperature, Dissolved Oxygen, Nitrate, Phosphate, pH, and Turbidity. Only two people where chosen to test the waters for Coliform bacteria. "Coliform bacteria are not pathogenic (disease causing) organisms, and are only mildly infectious. For this reason these...
  • Dissolved Oxygen Water Levels Gas
    629 words
    Research Dissolved oxygen infers to the volume of oxygen that is contained in water. Oxygen enters water through photosynthesis and across the water interface. The amount of oxygen that can be held by the water depends on the water pressure, salinity, and temperature. Gas solubility increases with decreasing temperature; thus colder water holds more oxygen. A reason why freshwater holds more oxygen than does saltwater is because gas solubility increases with decreasing salinity. When there is a ...
  • Inflowing River Estuaries Nutrients Water
    1,167 words
    An estuary is where the river meets the sea. Life in the estuary is depending upon salinity, which decreases from open ocean to the mouths of the inflowing rivers. As salinity declines, the assortment of life declines, because most estuarine organisms are marine. But they are high rich ecosystems, accounting for one-half the living matter of the worlds oceans. This high productivity is a result of a nutrient trap formed by the interactions of tides and inflowing rivers. Fresh water, lighter in ...
