Which accounts for the highest water withdrawls in the united states?
- industrial uses
- mining
- irrigation
- thermoelectric power

Thermoelectric power has highest water withdrawals in the United States.

Option D

Explanation:

In United States the highest usage of water is in the field of thermo-electric power generation.  Water from reservoirs, lakes and rivers are used to generate thermo-electric power. The water is used for cooling purpose and hence the water evaporates. Hence consumed water is not fully withdrawn back to the source of water. It is either withdrawn in parts or none at all.  

As population increases need for water increases. Effective watershed managements are now being utilized to reduce this consumption. To save water the people are made aware of the water conservation . Various new technologies and power generated by natural gas are being substituted to minimize water consumption.
