Monitoring Water Quality

Monitoring Water Quality. Water Test. 1. Salinity- Measures amount of dissolved salt in water Needs to stay fairly constant. 2. Dissolved Oxygen (DO) - measures the amount of oxygen in water Too little DO is bad (fish will die) Cold water holds more DO than warm water. pH.

  1. Monitoring Water Quality

  2. Water Test • 1. Salinity- Measures amount of dissolved salt in water • Needs to stay fairly constant

  3. 2. Dissolved Oxygen (DO)- measures the amount of oxygen in water Too little DO is bad (fish will die) Cold water holds more DO than warm water.

  4. pH • 3. pH - measures how acidic or basic the water is • 7.0 is neutral • 6.5-8.5 is acceptable range • Acid rain major source of the problem

  5. Phosphates/Nitrates • 4. Phosphates and nitrates- come from fertilizer and animal waste • Causes algal blooms which depletes the oxygen which kills the fish

  6. Temperature Temperature: average amount of heat in water Varies due to seasons or location (higher elevations have cooler water) Cold water is better because it holds more oxygen.

  7. Turbidity Turbidity- clearness of water Affected by sediment, excessive algae growth and storms. Cloudy water is bad.
