California imports the majority of its water from a blend of waters from the Colorado River and State Water Projects. In its raw imported state, it is full of contaminants. The contaminants of water from the State Water Projects come mostly from pesticide and herbicides that are from agricultural runoff, wildlife and wastewater.
The Colorado River supplies are the most vulnerable to contamination from recreation and urban runoff, storm water and from the urbanization of the watershed. Several forces impact the Colorado River as it runs through the towns of farmland, mining sites and industrial use land.
Municipalities, which use various sources of blends of this water must be ever diligent to be able to treat the blend that is occurring at any particular point in time. The contaminants from inorganic and organic chemicals,microbials (viruses and bacteria),radioactive particles from radioactive contaminants,industrial wastewater, including petroleum byproducts and human wastewater all require different and specialized formulations for treatment.
The California Department of Health Services prescribes regulation, which limits the amount of certain contaminants that can remain in the water though some of the contaminants are known carcinogens in greater amounts. They must be reduced to levels that are not harmful.

William--Too many people take their water supply for granted. Good information for your market!
William I have to tell you the problem with water is not limited to California. We here in Mississippi have the most strict pollution guidlines in the country and our water here stinks. Literally it stinks. The best "tap" water I have ever drank was in West Virginia. The run off from the mountain water is awesome.
Thanks Teri, I never see anyone writing about this. I tried to add just a touch of technical, but literally there are hours worth of reading on just this one subject. We all tend to take it for granted. it takes so much effort to purify water and it is getting harder and harder as more contaminates are requiring more chemicals and more systems to filter it. The costs just keep going up and so, bottled water will look cheap.
The Best I ever had was the natural spring water in the desert of Palm Springs. It is cold and fresh. I wonder with the chemicals it takes to clean it, what the long term effects of the chemicals even in the minimal amounts will do to us. The taste is poor but it is getting scarce and the taste may soon not be the worst thing about it. Getting it all will be.
I just posted this in a new group Eco-All Stars. Water and th efficacy of it is becoming a real concern here in California. We must all do a better job in our conservation and protection with the natural resource that cover a majority of the globe but most is not consumable without mans intervention.
