  1. WATER QUALITY!

  2. WATER QUALITY • WATER QUALITY- THE CHEMICAL, BIOLOGICAL, AND PHYSICAL STATUS OF A BODY OF WATER. • AMOUNT OF OXYGEN AND NUTRIENTS. • NUMBER OF LIVING ORGANISMS. • AMOUNT OF SEDIMENT IN WATER.

  3. Affects of quality water • Seasonal temperature changes, weathering of rock and soil, human activities, pollution, automobiles, deforestation, rain, and runoffs.

  4. Pollution • Point source pollution- pollution that can be traced to one location such as a drain pipe or a smoke stack. • Non-point source pollution- pollution that can not be traced back to one location. (lawns, roads, urban areas).

  5. Testing water quality • Dissolved oxygen- low=fish die, oxygen levels affected by chemicals which cause algae to grow.

  6. Water temperature • Water temperature- as temperature increases the amount of oxygen increases.

  7. Nitrates • Nitrates- nitrogen based compound often used in fertilizer. • Nitrates cause algae growth. Algae growth blocks light needed by plants, then plants die. When algae dies oxygen levels decrease.

  8. Acidity • Acidity- strong acids or bases can be harmful to plants and animals.

  9. Turbidity • Turbidity- the measure of cloudiness of water, from sediment, microscopic organisms or pollutions. • Amount of matter increases, turbidity increases! • Turbidity high- light penetration decreases • Turbidity measured with a secchi disk

  10. Bioindicators • Bioindicators- an organism that is sensitive to environmental conditions and is one of the first to respond to changes.

  11. Remote sensing • Remote sensing- collection of data from a distance
