There are MANY types Coliform and Ecoli for bacterium water test is the cheapest and doesn't check for most risks. Short series does the coliform, lead and nitrates.. Long Series checks for more minerals ph and tubidity. Also you want to check the operations of the well, who owns the well, who maintains the well and pumps and what happens when it fails - are you allowed by county to drill deeper

There are different types of water tests depending on what you are trying to determine. Bacterial is a Serial Dilution, Heavy Metals are checked with AA Analysis. Volatiles with A GC Analysis. 

Our inspectors have people to call and do these tests.

Haven't had one of those pop up before.  Guess they could use the free test kits at Home Depot.
