6 6. If the probable result determination is negative, the expert will refer the situation back to the County for renovation, repair, or replacement of the well by the NFWRF. REMEDIATION OF FAILURES Repair: Well repairs can be implemented for those situation involving known or discoverable flaws in the well construction. The repairs may involve the installation of a liner or sleeve in the existing casing; raising the well head above the finished grade; or deepening of the bore hole. The use of a well repair strategy is usually limited, especially when the well is more than 15-20 years old. Treatment: Treatment systems are indicated when they are the best solution for the well failure. Treatment systems may be the only remediation available for some well failure situations. Examples of treatment systems are whole-house filters, point of use filters, softeners, reverse osmosis units and neutralizers. Renovation: Renovation is generally indicated when there are certain types of non- pathogenic bacteria present in the well such as iron or sulfur bacteria. Over time, these bacteria cause an increase in undesirable qualities in the water and many times cause a slime to develop on the well walls or within the plumbing system that exacerbates the problem. The renovation process removes the slime and other buildup in the well and plumbing system through a chemical or mechanical process and eliminates or reduces the levels of nuisance constituents in the water. Replacement: Well replacement is indicated when the existing well is failing according definition established by this policy and the well cannot be renovated or repaired. Any new well may need a new pump, wiring and water line in order to be put into service which would be covered under the NFWRF.
