When coliform bacteria is present usually the next step is to chlorinate the well and house. Chlorination fixes the problem about 75% of the time, but there is no guarantee. Larry needs a full week to do a chlorination, if everything goes well. $350.00 which includes a potability re-sample.
Day 1 � Put granular chlorine directly into well at well-head & distribute chlorinated water thru out house including washing machine, dishwasher, ice-maker, etc. Chlorinated water must set in plumbing for minimum of 24 hours to kill the coliform bacteria. Do not use water except to flush toilet.
Day 2 � Pump out chlorinated water. A test reagent is used to make sure there is no chlorine left in the water. Water can be used for everything except drinking.
Day 6 � Pick up water re-sample & deliver it to a Colorado State Certified Micro Bacteriological Laboratory for a presence/absence (fail/pass) test of total coliform bacteria and fecal coliform bacteria.
Day 7 � Potability results from lab sent to you via email or fax.
