  1. Henry Hagg Lake Water Quality Report

  2. Location

  3. The testing site- Boat dock A

  4. A close up look at site

  5. Hypothesis • Water quality would decrease over the summer –temp. would raise, nitrate increase, oxygen decrease • Measurements • PH • Temperature • Nitrates • Dissolved oxygen

  6. Temperature • Temperature is very important to water quality • Temp Oxygen • It effects the rate of photosynthesis by plants and the sensitivity of organisms to toxic wastes and disease • The sun raises the temperature of water as well as thermal pollution from industry

  7. Dissolved Oxygen • Dissolved oxygen is important to the health of aquatic ecosystems • A decrease can endanger species • High levels of bacteria from sewage or rotting plants can cause % of saturation to decrease • A raise in water temperature can also decrease saturation

  8. Nitrate • Nitrate is a nutrient needed by all aquatic plants and animals • Decomposition of dead plants and animals and excretions of living animals contribute to nitrate levels • Sewage is the main source of excess nitrate as well as agricultural runoff • Excess levels of nitrate can increase plant growth and therefore decrease % oxygen saturation

  9. pH • pH can be affected by • Industrial waste • Agricultural runoff • Drainage from poorly operated mining operations • Many animals can be affected by even small changes in pH levels

  10. Data

  11. Conclusion
