So, are you saying that coliform bacteria is actually your only concern with your water? Additionally, is this for your home, or for something else like a business or farm?

Coliform bacteria contamination is a serious problem to deal with, but we can definitely help. There are a few options available for treating this situation, and the two most common are UV treatment and chemical treatment. Ideally, to be certain you are achieving proper disinfection, we always recommend using both chlorination and UV sterilization for a double barrier effect.
However, complete sterilization can be achieved with one or the other. Either way, it is good to proceed with caution and plan accordingly. I am including some more information on both options below.
The first and more common option uses chlorine injection with the use of a metering pump, which provides extra strength oxidation for coliform bacteria, as well as strong odors and high levels of iron and manganese (which can be linked with sulfur odors). The chlorine would then feed into a contact tank to provide enough time for the solution to react with the bacteria in the water, disinfecting it for good.
You could, as an option, send the water through a carbon filter to then remove the chlorine taste and odor completely. Because chlorine injection maintains a regular residual of chlorine throughout the pipes of your home, it is the more reliable and safer method.
The second, less reliable though quite popular method is a UV system for your whole house. Ultraviolet sterilizers work by exposing the cell walls of an organism to intense UV light which disrupts the genetic material and prevents the organism from reproducing. UV effectively destroys bacteria and viruses but is limited by the clarity of the water. UV only works on water that is clear and has a high UV transmission rate.

Unlike chlorine there is no downstream residual disinfection. Pretreatment for iron, sediment and excessive hardness minerals is recommended.
Chlorination:
Can be either 110 volt or 220 volt plug; can be hardwired to a pressure switch to come on with a well pump. Works with well water flow rates from 1 – 50 Gallons per Minute (GPM)
Output rating: 0.1 – 24 Gallons per Day (GPD). Pressure rating: Will inject into lines with up to 110 PSI.

Additional features: Degassing Valve is built in which makes this great for chlorination use. System includes Chlorination Pump, 10 Gallon Solution Tank, Injection Check Valve, tubing and installation fittings. 25 & 35 Gallon tanks also available for additional cost.
