Method for rid contamination (Shocking or disinfecting
- Locate well pipe.
- Bypass water purification system if present.
- Pour 1-2 gallons of chlorine (bleach) down well pipe.
- Run outside faucet until the smell of chlorine is obvious
and shut of (it may take 1-3 hours to smell chlorine at the
- Run all inside faucets and flush all toilets until the sell
of chlorine is obvious and shut of.
- Allow the chlorine to sit in the water system (well and inside
plumbing) for a minimum of 10 hours.
- Run outside faucet until the smell of chlorine is gone (can
take 10-12 hours). If pump in NOT in well, i.e., jet pump, run
water for two hours, shut water off, and repeat until smell
of chlorine is gone.
- Run all inside faucets until smell of chlorine is gone.
- Test for Coliform bacteria within one week after smell of
chlorine is gone. If the test is positive for Coliform, the
aquifer is probably contaminated. If this test is negative for
Coliform, the aquifer is probably good.
- If the aquifer is good, test for Coliform bacteria a month
after the first test. IF this test is positive for Coliform
, surface water is probably contaminating the well. If this
test is negative for Clifford bacteria, the original source
or cause of contamination has been corrected and the water should
be safe to drink as far as bacteria is concerned.
NOTE: Running the outside faucet for the majority of the water
reduces the amount of chlorine entering the septic system and
keeps most of the rest and grit out of the house. Water purification
system dealers can supply equipment to destroy Coliform bacteria.
