its brackish at least as far inland as stockton, but salt is not the problem with that water.. the problem is the high levels of dissolved fertilizer and pesticide from central valley agriculture. Those chemicals are fairly small molecules, so the only way to filter them out is through reverse osmosis, and if youre going to spend the money on that, then you might as well just use seawater. At present, reverse osmosis is so expensive that its cheaper to build dams in the sierra nevada, pipe the water over 100 miles west, pump it over another mountain chain into the bay area, and then under 5 miles of water into sf
