Performing the Tests
  • There were six tests used at each site.
  • Hardness
  • Alkalinity
  • Acidity
  • Dissolved Oxygen
  • Dissolved Carbon Dioxide
  • Temperature and pH
  • Each test was performed in order to determine the
    amount of each present in the water at that time,
    which allows us to observe if any changes have
    occurred.

5
Hardness Test
  • Historically, water hardness has been defined as
    the capacity of water to precipitate soap.
    Presently, hardness is defined as the
    quantitative measure of ions such as Calcium and
    Magnesium, present in a sample of water.
  • First, obtain a 5 ml water sample and add 5 drops
    of reagent 1. Next, add 1 drop of Eriochrome
    indicator solution and swirl in tight circles.
    The solution should turn a red-violet color. Now
    take the titration syringe and fill it with EDTA.
    Begin the titration by carefully adding one drop
    at a time until the solution becomes purple, then
    swirl for 15 seconds after each additional drop
    until the solution becomes blue. Finally, read
    the number of ml used during titration and
    multiply by 300 to obtain ppm of CaCO3.
  • The measure and control of water hardness is
    essential to prevent clogging in water pipes.

6
Alkalinity Test
  • Alkalinity is the quantitative capacity of water
    to neutralize an acid to a set pH. This is
    important in determining the corrosive
    characteristics of water due primarily to
    hydroxide, carbonate, and bicarbonate ions.
  • The Alkalinity test begins by adding 1 drop of
    Bromophenol blue to a 5 ml sample of water. If
    the solution turns yellow, then it is acidic and
    the acidity test must be carried out. If the
    solution is green or blue, then reagent 3,
    Hydrochloric acid must be titrated into the
    solution, swirling after each drop. The number
    of drops should be counted until the solution
    turns yellow. Yellow indicates the solution is
    Alkaline. Multiply the ml titrated by 300 to
    obtain ppm of CaCO3.
  • Alkalinity is critical in the treatments of
    drinking water, wastewater, boiler and cooling
    systems, and soils.

7
Acidity Test
  • Acidity is the quantitative capacity of water to
    neutralize a base to a set pH. Therefore, the
    greater acidity, the more corrosive the water.
  • The Acidity test begins by adding 1 drop of
    Sodium Thiosulfate and Bromophenol blue to a 5 ml
    sample of water. If the solution turns blue,
    then the acidity is zero. If the solution is
    yellow, then reagent 4, Sodium Hydroxide must be
    titrated into the solution, swirling after each
    drop. Count the number of drops until the
    solution changes from yellow to blue. Blue
    indicates the solution is Acidic. Finally,
    multiply the ml titrated by 500 to obtain ppm of
    CaCO3.
  • Today, water supplies are becoming more
    contaminated with corrosive chemicals due to
    industrial dumping or acid rain, therefore,
    acidity measurements are essential for monitoring
    and controlling pollution levels.

8
Dissolved Oxygen Test
  • The concentration of dissolved oxygen in water is
    extremely important in nature. In oceans, lakes,
    rivers , and other bodies of water, dissolved
    oxygen is essential to the growth and development
    of aquatic life.
  • The test for dissolved O2 begins by adding 5
    drops of Manganous Sulfate and Potassium
    Hydroxide to a glass bottle with a sample of
    water. Shake vigorously and then allow to stand
    for 1 minute. Next, add 10 drops of Sulfuric
    Acid and shake vigorously until precipitate is
    dissolved. Now take 5 ml of the solution and add
    1 drop of reagent 4, then titrate Sodium
    Thiosulfate into the solution until it changes
    from blue to colorless. Finally, multiply the ml
    titrated by 10 to obtain ppm of O2 in the water
    sample.
  • Without oxygen, water can become toxic due to
    anaerobic decaying of organic matter.

9
Dissolved Carbon Dioxide Test
  • Certain CO2 levels are required in nature and in
    mans environment, however, stagnant or polluted
    water can generate large amounts of CO2 due to
    decomposition. This can cause the water to
    become corrosive and toxic to aquatic lifeforms.
  • The CO2 test begins by adding 1 drop of
    Phenophthalein indicator solution to 5 ml of
    water. If the solution turns pink then CO2 is
    zero. If the solution is colorless, then titrate
    Sodium Hydroxide into the solution until it turns
    pink. Finally, multiply the ml titrated by 100
    to obtain the ppm of CO2.
  • In water systems, a delicate balance of CO2 must
    be maintained to prevent corrosion or
    encrustation of pipes.

10
pH and Temperature
  • pH
  • The pH scale is used to measure the acidity or
    alkalinity of a solution.
  • The pH value indicates the concentration of
    hydrogen ions in the solution.
  • Temperature
  • Temperature is the measure in degrees Celsius of
    a solution.
  • It is important to note that the temperature of
    the water will effect the data a great deal.
  • For example the warmer the water the more growth
    will occur, causing increased CO2 and decreased
    O2.

Examination of Water Samples
  • Water samples were taken home in mason jars and
    then filtered using a hand pump filtration
    device.
  • During this process the contents of the jars were
    trapped onto filter paper and then examined under
    a microscope.
  • Examining the filter paper was necessary in order
    to discover what type of organisms were present
    in each sample.

14
Interpretation of the Samples
  • The interpretation of the water samples has not
    been started yet because the project is being
    carried over into next semester.

Overall Status of the Project
  • What has been done thus far
  • I have performed various tests that allow me to
    draw short-term conclusions for this project.
    However, at this time the status of the project
    is incomplete due to its carrying over into next
    semester.
  • Steps to be taken next
  • In the following months, I will continue to visit
    each site, performing each of the tests many more
    times. I will also begin to examine each of the
    water samples to determine the contents of the
    ponds.
  • Finally, I will devise long-term conclusions
    based on the results that were gathered and
    finish with some concluding remarks.

23
The First Site
  • This site is the large pond directly behind Dr.
    Tietjens home.
  • It is located in Shelby County, next to Guist
    Creek and was a National Fish Hatchery for many
    years. This body of water is much deeper than
    the others.

24
The Second Site
  • This site is across from Dr. Tietjens home and
    is separated from the first site by a dam. This
    site will occasionally flow into the first site.
  • The second site also catches much of the run off
    from the farm on the hill behind it.

25
The Third Site
  • This site is located in Franklin County and is a
    National Fish Hatchery. This Hatchery deals only
    with warm water fish such as bass, catfish and
    blue gill. The Frankfort Fish Hatchery is also
    responsible for producing a large part of the
    fish that are stocked in lakes and ponds
    throughout the state.

26
Results of the Project
  • Due to the carrying over of the project into next
    semester, the results at this time are
    indecisive. Many speculations could be drawn at
    this point using the information already
    obtained, but no concrete evidence has been
    observed to suggest that this is reasonable.

27
Concluding Remarks
  • Due to the carrying over of this project, The
    Concluding Remarks are not available at this time.

28
Acknowledgments
  • At this time I would like to thank the many
    people that helped with this project.
