Well Disinfection

Disinfection of a well – AKA Well shocking – is the process of injecting a high concentration of a chlorine product into the well to try to kill any free-floating bacteria.

As we live in upstate NY, we are used to higher than normal pH levels in our water – sometimes as high as 12. Liquid bleach struggles to kill bacteria in water with a pH higher than 8.5. At Hawk Drilling Company, we use a product that is less affected by pH and is always 50% disinfective (bacteria-killing) versus oxidative (casing breakdown). Often, the struggle with disinfection is that it doesn’t work the first time, so the owner does it again adding more liquid bleach. As bleach also has a high pH, this raises the pH more, making the bleach even less effective in killing bacteria.

Our highly trained technicians understand the importance of injecting the accurate amount of product, monitoring for potential complications, such as pump plugging, helping to prevent further contamination by replacing an improper well cap and giving you the confidence/education you need to complete the project for best effectiveness. 

What is involved in proper disinfection?

  • The technician(s) will evaluate what is present for water treatment and bypass, as needed.
  • A hose is attached to the pressure tank and hoses are then run to the well head. 
  • The specifications of the well are evaluated – depth (if known), pump size, and static level of the well. This info is used to calculate the appropriate product. The product is slowly injected into the well head, while the pump is recirculating back into the well. 
  • The super-chlorinated water is recirculated back into the well head until the proper amount is noted by the test strip.
  • The technician then runs the super-chlorinated water to each faucet/shower. 
  • The water must then sit for approximately 24 hours to allow contact time.
  • Directions, test strips, and a hose are left for the homeowner to run the well to clear after the appropriate contact time.
  • Once the well is confirmed clear of chlorine, a resample for bacteria is scheduled at least 48 hours after. 

Expectations during a disinfection:

  • The homeowner should not run significant amounts of water into the septic system and should instead plan on showering elsewhere. We encourage customers to fill buckets or a bathtub with water (before the disinfection) to use for toilet flushing.
  • It can take anywhere from 1 hour to a few days to completely flush the well of chlorine.  The amount of time depends upon the depth of the well and the recharge rate. A well with a recharge rate of 50+ GPM will clear much more slowly than a well that can be run dry. 
  • The water quality will be affected during this time as there will be a lot of disturbance in the well. It is recommended that water treatment be kept in bypass until the resample is taken. Cartridge filters may need to be replaced as they can be plugged during this process. 

No one can guarantee that a proper disinfection will work to remove bacteria, as the water feeding the well could be the concern. We guarantee that the process is completed correctly the first time and further intervention would need to be moved into the house with water treatment, such as an Ultraviolet Light

Someone hacked into my account. I have recommended this... company in the past. They are very good. I am sorry you had to experience this wrongdoing by someone pretending to be me. Thank Youread more
During the process of buying a new home, we encountered... some well issues and sought assistance from Hawk Drilling. I was amazed by their attentiveness and willingness to help. Hawk Drilling assisted us through the many steps of the process, well shocking, testing, and water filtration installation. Not only were the ladies behind the phones extremely helpful the many times I called, but all of the workers who showed up were professional, friendly, and informative to what they were doing. I would highly recommend Hawk Drilling for any of your well needs, and I will definitely be using them in the future.read more

I reached the point with my water problem that I didn’t... know what else to do. Then I reached out to Hawk. They saved my sanity. After dealing with 3 companies that tested water, recommended the usual, charged me a fortune, and didn’t solve the problem Hawk did much more specific testing and found the problem. They developed a specific water filtration system and the water is now normal. This company has experts that are the best, they always go the extra step to problem solve. Most importantly they show genuine concern for their customers and run an ethical company. I’d definitely give them 10 stars if I could. By the way their price was more than fair considering all the work they did.read more

I could not be more satisfied with this company. I had a... very tough well situation with a tough install. Sandra managed my expectations along the way and made every effort to save us money and unnecessary strife. The tech's were clean, skillful, and efficient. I agree with the previous poster - "family run business that treats the customer like family." The service industry has taken a hit, but I am relieved to know there are still gems out there. Thanks Hawk Drilling!read more

We have had Hawk Drilling out to our house 3 times since we... purchased it back in November of 2021. Cannot say enough great things about them. They have been able to troubleshoot some complicated issues with us quickly, affordably and reliably. From the team that answers the phones, troubleshoots and dispatches to the team out here doing the work, they are really top notch and a pleasure to do business with. Huge shout out to Shawn and Chris who were just here this morning and had me back up and running within 5 minutes. Highly recommend Hawk Drilling.read more

We had recently purchased a new house with a well which... needed total replacement ( the original well was less than 20 feet deep and contaminated with road salt). Hawk was recommended to us by a friend, and we could not be happier!We were scheduled into the books for water testing just a few days later. Sandra was extremely knowledgeable and provided all the information we needed. After five long months of closing, we had called to have our well drilled.Amanda was able to get us in that next week, and well drilling started just a few days after, which we were thrilled about as we had no access to usable water! Jeremy bumped us ahead in the schedule due to weather and we had a completed well in a day and a half. We were able to borrow hoses to run the water for as long as we needed.The Hawk Team is professional, prompt, and incredibly knowledgeable (and a bunch of dog lovers!). I received weekend phone calls to check on the water even though they were not open. Hawk cares about its costumers and provides 10/10 service. Will always highly recommend.read more
Did a great job and the price is the best around and you... get quality equipment. And they came early given the emergency situation being without water. TODAY I WAS AND AM EXTREMELY GRATEFUL FOR HAWK WELL DRILLING!read more

Called Hawk Monday afternoon, Amanda set up an appointment... for my pump to be looked at. Bill and Sean arrived 10 minutes AHEAD of schedule, and told me they could have a new pump installed right then and there. They were done in less than 2 hours! Cleaned up the area, tested the pump and made sure everything was working. Absolutely 100% recommend Hawk Well. They have a new forever customer. Extremely happy with them!read more
