Please identify or describe additional hydrologic or geographic conditions that you believe may affect the shape of the WHPA for this source. Where possible, reference them to their location on the map.
Only ‘Non-Community’ Public Water Systems need to complete this part. Name and describe the management strategy (or strategies) you are planning to implement to help reduce the potential for contamination of the drinking water supply by the potential contamination source(s) located within the Wellhead Protection Area (WHPA). Also, please include the date you will begin implementation of each strategy. Complete this form for each potential contamination source. * Plan additional controls for inadequately controlled potential contamination sources. * Set an implementation date for each additional control. Example: Potential Contamination Source: Residential sources of pesticides and fertilizers Existing Controls: Manufacturers’ guidelines prescribe safe handling and application of chemicals. Adequately managed? No, highly vulnerable aquifer thought to require additional controls. Strategy 1: Acme Lawn Care - Description: Establish an agreement for them to install spill protection in their bulk mixing area. Implementation Date: 3/15/95 Strategy 2: Public education - Description: Issue an educational brochure to homeowners about the proper use of pesticides and fertilizers within source protection areas. Implementation Date: 4/21/95 Potential Contamination source: Existing Controls: Adequately Managed? Strategy 1: Description: Implementation Date: Strategy 2: Description: Implementation Date: * Keep Records File Copies of all public education programs, letters, memoranda of agreement, memoranda of understanding, permits, etc., for this potential contamination source behind this cover sheet.

List possible alternative water sources that could be used in the case of a service interruption or contamination event. (If the alternative is a nearby well, indicate whether it develops water from the same aquifer as main water supply well, if known.): List emergency funding source(s) that may be utilized to prevent interruption of the water supply or to restore the water supply.
