I can understand your concern.Taking the salt out
of sea water to make it drinkable would probably
be only one of the steps. Big things like
hospital waste would be screened out and the water
would be purified to prevent diseases. I'm sure
you have noticed that the beaches sometimes have
to close due to disease organisms in the water, so
you wouldn't want to drink it either. For more

Their main page,
has general information on water in SB county.
I don't know how they remove hydrocarbons (oil
residue). You might contact your local water
provider for information on that. Even without
spills, we release a lot of oil into our water by
not recycling oil in our cars.
only 1% of the world's water is fresh water, and
only a fraction of that is drinkable, so we need
to take care of it.
Thanks for asking.
