In order to conserve the Sierras snowpack, more water is being imported from the Colorado River. About half of Los Angeles' water flows from the Colorado River via the Colorado River Aqueduct.
What is the largest source of water in California?
Accounting for one-third of California’s total water supply, the Sierras are the state's largest source of water. When rain falls in the winter at higher elevations, it becomes snow. When that snow melts in the springtime, the melted water becomes runoff and flows into aqueducts and groundwater.
What would Smith's method allow us to do?
Instead of dumping waste back into the ocean, Smith’s method would allow us to recycle an entire city’s potentially hazardous waste into clean drinkable water.
Why is water running low?
Another reason that our sources are running low is due to water leaks and evaporation in the water transport system. When water moves from the Colorado River or the Sierras, through an aqueduct to Southern California, water can leak out of the aqueduct into the ground or is simply evaporated.
Why is the current water system ineffective?
The main reason why this current system is ineffective is because we use clean purified water for everyday activities like gardening, drinking and cleaning the toilet.
What is reverse osmosis in wastewater treatment?
New research shows that wastewater treatment plants that employ a combination of purifying techniques followed by reverse osmosis – a process by which water is forced through a barrier that only water can pass – do a good job of removing chemicals that may elicit health effects.
What does a sandbox do?
They produce water to irrigate crops, highway landscaping, golf courses and parks, as well as to be reintroduced into the ground for groundwater recharge, which ultimately could end up in drinking-water supplies. While this treatment process has the promise to save an evaporating natural resource, Pedersen points out that little is known about just ...
Does wastewater contain hormones?
