I take samples of the water at the most used faucet . I send the samples to a labratory for water quality testing .
   There are 2 basic water quality testing most performed .
  ( 1 ) Total Coliform Bacteria ( Bacteria in water )
  ( 2 ) FHA required Testing =Test for  Bacteria , Lead , Nitrate, Nitrite
 
 It is also recommended to inspect the well for open areas and broken seals . This could cause contamination.
