The Ogallala aquifer underlies Midwestern states, including Texas, Oklahoma, and New Mexico, while California, Arizona and Nevada use the Colorado River as their primary water source. All show serious groundwater overdraft. Recall that effluent streams act as discharge zones for groundwater during dry seasons. This phenomenon is known as base flow . Groundwater overdraft reduces the base flow, which results in the reduction of water supplied to our streams.
Desalination is the removal of salt from seawater.
This Reclaimed Water, it is highly available, cheap, and is one central answer to our water supply needs in the future. It is also a good example of using recycling to increase sustainability of our economic and cultural systems.
