    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(Mcwelsh and Raintree, 1998). Phosphates are present in fertilizers and laundry detergents and can enter the water

  • Science Experiment to Measure the Dissolved Oxygen Levels Using the HACH Method and CHEMets Test Kit

    Science Experiment to Measure the Dissolved Oxygen Levels Using the HACH Method and CHEMets 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® method or the newly developed CHEMets® 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® method or

  • Lake Tarpon’s Water Quality: Change over an Eight Year Span

    worsened. The variables that will determine whether the quality has changed are: nutrients (phosphates and nitrates) and dissolved oxygen (DO). The expected changes are lower dissolved oxygen levels (from the already low levels), higher nitrogen levels (from the already high nitrogen levels), and the state qualifications still are not met for nutrients and dissolved oxygen (Levy, Flock, Burnes, Myers, Weed, River 2010). This topic relates to environmental management because the changes in water

    the lake’s pH and dissolved oxygen levels in areas of frequent boat and motor activity and create a disturbance in the lake’s biodiversity due to the toxins in the various types of fuels burned. Dissolved oxygen and pH levels influence the abundance of fish. In high enough amounts, metals may be toxic to fish, wildlife, and or microscopic animals. Local lake water will need to be tested in order ... ... middle of paper ... ...e effects on the lake’s pH and dissolved oxygen levels. The lake’s

    was thought that this relationship was because lowered measured concentrations of dissolved oxygen puts stress on the aquatic system, the change in gross and net primary productivity would be apparent in systems exposed to lower intensities of light. The range of positive net productivity would be bounded by average primary productivity at 100 percent light and minimum percent light to maintain levels of dissolved oxygen. This lower bound would most likely be an amount greater than 10 percent light

  • Water Quality Essay

    Measuring the level of dissolved oxygen chemically and biologically (COD, BOD) - Measuring the amount of bacteria - Biological sample There are so many other ways to measure water quality. In this lab report, we are going to discuss BOD, biochemical oxygen demand. What is BOD ? BOD determines the quality of water by measuring the amount of dissolved oxygen in the samples. The oxygen in the water is usually from photosynthesis of aquatic plants and oxygen from the air that dissolved into the water. Bacteria

    evaporates, or starts to steam, therefore losing the dissolved oxygen into the atmosphere. The amount of oxygen that dissolves in water can vary through daily and seasonal cycles, and can decrease with higher temperature, dissolved salt content, and elevation of the body of water. Surface water, near the water-air boundary and with adequate light for photosynthesis, is generally saturated or even supersaturated with oxygen; this is because dissolved oxygen comes from the atmosphere and from photosynthesis

  • Chemical Process Of Aerobic Treatment: A Biological Process

    free or dissolved oxygen by microorganisms (aerobes) in the degradation of organic wastes. Since oxygen is available to working aerobes as an electron acceptor, the biodegradation process can be significantly accelerated, leading to increased throughput capacity of a treatment system. Factors influence on treatment process In order to provide high-rate oxidation of organic pollutants, microorganisms must be provided with an environment that allows them to thrive. Temperature, pH, dissolved oxygen

  • The Effects Of Temperature On Water

    750 Words  | 3 Pages

    high water temperature occurs which causes evaporation of certain substances that may be present in the water. Also, as water temperature increases, the solubility rate of gases in water, such as oxygen (O2), decreases and respiration rates of aquatic organisms increases which results to greater oxygen consumption (Chapman and Kimstach 1992). A change in water temperature also causes greater destruction of aquatic life and problem of unwanted growth of water plants and wastewater fungus (Metcalf

    Water bodies both produce and consume oxygen. It gains oxygen from the atmosphere and from plants as a result of photosynthesis. For flowing water it would dissolve more oxygen because of the effect of its churning and continuous movement. Waste water containing organic materials are decomposed by microorganisms that utilize the oxygen within the stream. The Biochemical Oxygen Demand (BOD) is the amount of oxygen consumed in this process. Other sources of oxygen consuming waste include storm water
