Dear good people,

Recently I read an advertisement from a company selling 
"water purification system".    The ad claims that they
have a machine that will shine a strong UV light to tap
water, and the water comes out "cleaned from germs".

Can this be true?  I thought that UV does not penetrate
well in water.
