Water Quality: used to describe the health of a water system.
Health of water is determined by:
1. chemical variables/properties
2. physical variables/properties
3. biological (environmental stressors)/properties
Turbidity (NTU) is often measured by using a Secchi Disk: A flat, white disk lowered into the water by a rope until it is barely visible. At this point, the depth of the disk from the water surface is the recorded secchi disk transparency.
3. Water Movement
Using technology to monitor water quality will help humans provide treatments to improve conditions in Earth’s oceans and freshwater.
Technology and Indicators used:
pH scale: rating of how acidic or basic a substance is; the scale goes from 0 to 14 with 7 being neutral values less than 7 being acidic and values greater than 7 being basic. (surface water 6 – 9; salt water 7.7 – 8.1)
