Well Chlorinations

The EPA says that any water that has Total Coliform or E. Coli, should be treated.

The State of NC says that the treatment is to "chlorinate" or "shock" the well.

The State rules say only the well owner or a NC Licensed Well Contractor should treat the well.  The rules also lay out how it should be treated
(and it doesn't involve bleach from the grocery store).

Save time and money:
Do it right the first time.


The water cannot be used during the treatment process!

When we do retests for wells where the homeowner "chlorinates" their own well, we find that these often fail as homeowners do not have the right chemical, equipment, and knowledge to do it effectively.

Some well contractors offer a cheaper service but they don't follow the rules & procedures laid out by the state and these frequently fail the retest as well. (It's true: You get what you pay for.)

The water is not safe for human contact or consumption during the treatment.

Do not use for drinking, cooking, washing, laundry, watering animals, etc.

It is not good for septic systems, so we recommend avoiding flushing the toilet (unless you use a water jug).

Chlorination Price

(Prices are subject to change.)

All Prices include service in Buncombe county.

For other counties, there will be an additional trip fee as listed on the Trip Fee Page.

  • We use contractor grade chemical.

  • We calculate how much to use based on the specifications of the well.

  • We start the treatment.

  • We circulate the treatment through the system.

  • We "run off" the treatment.

  • We INCLUDE a basic bacteria Water Test!

Our chlorination service starts at $400 for wells up to 400 ft deep.

Its an additional $100 for up to an additional 100 ft.
(so a 455 ft well is $500, a $500 ft well is $500, a 525 ft well is$600, etc)

Things to know:

  • By the state rules & procedures, treating the well takes at least 2 days.

  • If all goes well, the water test can be taken on the second day and it takes about 2 business days to get the results.​

    • The science behind the tests take a certain amount of time - unfortunately there is no way to "rush" it.

  • We do take payment up front to schedule.

    • If cancelled one business day before, the service and trip fee are 100% refundable.

    • You can pay with a debit/credit card (Visa, Mastercard, or Discover) over the phone or online from the invoice

  • For wells (and most springs), water and power need to be on and running to a spigot or faucet.

    • If water and power are not on when we arrive, we cannot preform the treatment and a wasted trip fee will be charged.

    • House must not be "winterized"

    • If you are the buyer, please have your agent let the list agent know that the house cannot be winterized, and water and power must be on.

  • Depending on the well conditions, components, recovery rate, etc, we may need to come back a third day to complete the runoff and collect the sample.

    • The water should not be used until the runoff is completed!​

  • Chlorination works for 99% of standard wells.

    • Occasionally, a well will need a second treatment.

    • Rarely, a well will have an underlying condition that is causing the bacteria and chlorination will not produce a clean test. In that case, most people install a uv light.

  • Depending on the set up, we can chlorinate a spring that feeds a house. 

    • Springs are literally water coming up through the dirt - they are going to have bacteria.

    • Depending on the set up and components a spring fed system can be chlorinated and will produce a clean test.

    • However, bacteria can come back very quickly. You may want to test it more frequently and possibly consider adding a uv light.

  • Reports/Results are released to whomever paid for them​

    • If they can authorize us to release them to additional people.​
