OUR WELL DISINFECTION PROCEDURES INCLUDE THE FOLLOWING
• Inspection to assure adequate construction for prevention of direct entry of contaminants. This includes inspection of the height well casing and type of well cap.
• Review of existing water treatment systems which might contribute to a questionable water analysis result (heterotrophic bacteria), or require disinfection in a separate procedure. This includes water softeners, RO units, iron, arsenic and carbon filters, as well as refrigeration filters. Some types of systems do not tolerate high levels of chlorine, or will remove chlorine.
• Chlorination of the well to include rinsing of the well casing, and assurance of adequate chlorine levels to the house.
• Providing you with a testing capability for determination of chlorine levels to assure adequate disinfection of all house lines, and to determine when to repeat the bacterial analysis.
It is recommended that you have a repeat bacterial analysis performed approximately 5-7 days after a negative chlorine residual test result.
Well disinfection should not be considered a permanent correction measure for a residential ground water source with continuously exposure to microbiological contamination, resulting from improper location or construction (Bucks County Department of Environmental Health).
