8-14: alkaline
7: Neutral (best)
Term
pH Factors

Term
Temperature Change
Definition
...kind of self explaining, don't you think?
Term
Temperature Change Factors
Definition
1. Slower Areas (slower=warmer)
2. Direct Sun
3. Thermal Pollution
4. Deeper Depth (cooler)
Term
Nitrates/Phosphates
Definition
Tests for fertilizer-> fertilizer=nutrient.
Term
N/P Factors
Definition
Fertilizer Application
Term
Turbidity
Definition
Keeps light from penetrating into the water and interferes
with plant photosynthetic oxygen production and primary productivity. Darkened
water holds more heat, increasing the water temperature, which in turn lowers the DO.
Term
Turbidity Factors
Definition
1. Sediments
2. Fish life
3. Waste
4. Algae growth
5. Urban runoff
