What is the Global Water Sampling Project?

• The GSWP is a fresh water-testing project
  performed by high school middle school students
  across the world from India, Romania, Italy the
  United States comparing and contrasting water
  quality data they have collected from their local
  fresh water reservoir.
• Each school collects date for seven weeks and the
  posts their results on a ceise website to compare
  data.
• The purpose of this project is to see and test
  the physical and chemical water qualities and
  ones local fresh water source and to see how
  similar or different this data is with other
  water sites across the globe.

Purpose Statements

• To evaluate the quality of the water in the LA
  River based on its interaction with chemical
  substances and organisms.
• To come across the relationships among the data
  collected by all project participants.

History of LA River

• Starting point
• - Joining of the Bell Creek and Calabasas Wash
  (southwestern part if San Fernando Valley)
• Sources San Gabriel Mountains, Santa Susana
  Mountains
• Major Tributaries Browns Canyon Wash, Aliso
  Canyon Wash, Tujunga Was, Western Burbank
  Channel, Verdugo Wash, Arroyo Seco, Rio Hondo
  Compton Creek
• Flow
• - East through the San Fernando Valley to city of
  Burbank, where it turns south and southeast,
  through the Santa Monica Mountains and the
  Verdugo Mountains.
• - This flow is known as the Glendale Narrows.
• Main water supplies
• - Sewage
• - Industrial discharges
• - Runoff from urban cities
• Uses
• - Before act as a flood control channel
• - Now living space for the homeless with
  graffiti along its walls
• Pace of River

Hypothesis

• Notre Dames Hypothesis for the Global Water
  Sampling Project was that the pH, nitrogen,
  temperature, and phosphate levels at the Los
  Angeles River will be suitable for sustaining
  life.

11
Procedure

• We tested for temperature, phosphates, pH, and
  nitrates
• Each procedure was alike
• We recorded date twice a week
• For temperature, the person testing put a
  thermometer in the water. Then, he/she would wait
  and record temperature in degrees Celsius
• For pH, Nitrate Phosphate, A sample of water
  was needed. Once he/she put some sample in a test
  tube, color indications were dropped in test
  tube. Then he/she would wait 1-10 minutes. After
  waiting, he/she would compare to other colors
  that designate pH, Nitrate Phosphate levels
• With all the comparisons finished, tester would
  have to record readings and share data with the
  class.

Qualitative Analysis

• Nitrates, Phosphates, pH Temperature can affect
  water quality because they all have a direct
  affect on the water.
• Factors such as air temperature, air quality, and
  natural events may have affected the results of
  our data collections because all of these factors
  affect the water we were testing.
• The Nitrate data collected by Notre Dame High
  School was not like the nitrate collections made
  by the other schools.

19
More Qualitative Analysis

• When comparing the Phosphate values collected
  from the Los Angeles River with the data
  collected from the other schools test sites, the
  results were not similar.
• The average water temperature for the Los Angeles
  River was 24oC
• The pH readings that we got were similar to the
  readings of the other schools testing at a
  river.

20
Conclusion

• Our hypothesis stated that pH, nitrogen,
  temperature and phosphate levels at the Los
  Angles River will be suitable for sustaining
  life. Our hypothesis was correct.
• For pH the normal range of stream water is
  between 6 8. At the Los Angeles River, the
  average was 7.9
• Nitrogen was needed in our test site for
  organisms because nitrogen compounds are basic
  building block in animal biology. Our Nitrogen
  levels were normal meaning, organisms could
  survive.
• Our average temperature of 24.25 degrees Celsius
  was in range.

21
Cont. Conclusion

• Our phosphate level is within the range and was
  1ppm.
• Our data was different compared to other global
  water quality tests, but makes sense because
  temperature change frequently can vary place to
  place.
• If we were to participate in this project next
  year, we would make sure to get all of the data
  recorded each time we went to test. We would also
  want to test different areas at our site to see
  any differences.
• We are very happy with our results and glad this
  project was able to teach us so much about our
  own Los Angeles River
