Bacteria Testing & Removal

Concerned About Bacteria in Your Well Water?

A bacteria (coliform) test is crucial to ensuring the water in New Hampshire wells is safe to drink. Coliforms are naturally occurring bacteria present in the environment and used as an indicator that other, potentially harmful, bacteria may be present. Fecal coliform and E. coli bacteria in well water indicate the water may be contaminated by human or animal wastes. These bacteria are harmful to human health. As coliforms can be found in plant and soil material, the bacteria can pass into water through defective or aged well construction, such as through caps or faulty seals, cracks, or holes in the well casing, or quite commonly in New Hampshire, during well flooding at the end of winter. 

Bacteria Sources & Pathways

  • Runoff from woodlands, pastures, and feedlots; septic tanks and sewage plants; and animals (wild or domestic).
  • Backflow from contaminated sources such as a sink-top carbon filter or bucket of water.
  • Reduced pressure or suction in water lines that draw in soil water at the pipe joints.
  • Through faulty sanitary seals in the well system such as when the well cap, grout around the well casing, or pitless adapter that connects an underground water distribution pipe to the well are compromised.

Many types of bacteria are native or adapted to saturated sediments and rock, and are present in significant numbers in aquifers.

Since bacteria infected water is odorless and tasteless, and contamination cannot be visually ascertained, a total coliform test should be done by a trusted water treatment specialist to determine the presence of fecal coliforms and, most importantly, E. coli, which is known to cause serious illness. While coliform bacteria, in general, may not cause illness, its presence is often an indicator that other disease-causing organisms, such as E. coli, may be present.

The total coliform test is a two-step process, first to determine whether or not coliform bacteria exists in the water, and second to determine whether the bacteria is of fecal origin. If the presence of these bacteria is confirmed, Capital Well Clean Water Center has you covered. Forget about juggling contractors; our team will work with you from the first step to the last, including well repair or replacement services (if necessary). We care for your systems—and the health and safety of your family’s drinking water—as if it were our own.

  • George Craggy

    Jonathan, I wanted to drop a couple of lines to tell you how satisfied and happy that I chose Capital Well Co. for my water needs. From your lead man Steve to your drill people, your plumbing guy and your guy on the back hoe. Everyone that cast a shadow on my door threshold were polite, professional and willing to take the time to explain and answer my questions; which were many . Jon, it was my pleasure to meet you today and pleased that you came by for a follow up visit and explain how the heater works. SO...if I get a chance to tell everyone that needs a new well, I definitely will. It is apparent there is no "I" in your team . Thank you everyone.
  • Richard Meaney

    Mr. Swain, Thank you so much for the service Capital Well provided at my home today. I left a message with you at the behest of Ed Monty. I received a prompt phone call from Greg to arrange for a service call and to discuss what might need to be done. Promptly at (actually a few minutes before) the scheduled time, Bobby showed up to perform the service. Bobby was excellent at explaining the service, why some things were needed and how the well and pump worked, and answered all of my questions to my satisfaction. All in all, this was a very positive experience for us. Thanks to you and the people at Capital Well for prompt, courteous, and efficient service.
