  1. 2. - microscopic plants that consist of photosynthetic pigments.
  2. 6. - excessive plant and algal growth due to the increased availability of one or more limiting growth factors needed for photosynthesis.
  3. 8. - are single-celled plants that can ingest food and reproduce at rapid rates if the water’s pH, food supply, and temperature are ideal.
  4. 10. - critical water quality parameter
  5. 12. - an instrument used by determining the degree to which particles suspended in the solution decrease the intensity of light lost as a beam is passed through it.

  1. 1. - If a small amount of this is found in water, this indicates that the water is clean and essentially free from contaminants.
  2. 3. - indicates the water’s acid-neutralizing capacity.
  3. 4. - essential for life, used heavily in agriculture and fertilizers. (i.e. Nitrogen and Phosphorous)
  4. 5. - measures how well a sample of water or similar solution can carry or conduct electrical currents.
  5. 7. - the amount of dissolved salts present in water
  6. 9. - commonly caused by the presence of mineral acids, hydrolyzed salts, and carbon dioxide.
  7. 11. - occurs when water contains high mineral levels.
