Chlorine / Hydrogen
A chlorination and hydrogen peroxide injection system eliminate bacterias like iron bacteria, sulphate bacteria, coliforms and E.coli. In most cases they also eliminate the need to shock your well as all water is being treated at surface before point of use. This type of system will also eliminate odour plus improve the taste of the water.
Alberta Health Services (AHS) recommends that private water wells be tested twice annually for harmful bacteria. With either of these types of systems, if maintained properly, this testing would not be required.
