Question

In considering the water quality in and around the U.S., the EPA analyzes critical chemical and physical states: oxygen, nutrients, pH,
salinity, other chemicals and temperature, light, and hydrology including rainfall, flow rates, and sea level. ALL BUT ONE could be a

pressure that results in the changes in chemical and physical states.

es )))

changes in sea level

Answer 1

Answer:

wastewater and fertilizer runoff

Step-by-step explanation:

Factors such as temperature, pH electrochemical (redox) potential, and the transparency of air and water can affect the chemical and physical characteristics of ecological systems. This are as a result of activities like climate change, water contamination, and changes in water runoff.

Wastewater and fertilizer runoff causes low amount of dissolved oxygen  in water, which affect biological communities and cycling thereby resulting in chemical and physical states changes.
