40A-3.502. Construction Methods  


Effective on Wednesday, August 15, 2018
  • 1(1) Wells must be so constructed, cased, grouted, plugged, capped, or sealed as to prevent uncontrolled surface flow, uncontrolled movement of water from one aquifer or zone to another, contamination of ground water or surface water resources, or other adverse impacts.

    42(a) For public water supply wells connected to a community water system on or after August 28, 2003, except those connected under a construction permit for which the Department received a complete application before August 28, 2003, continuing protection of the well from the sanitary hazards shall be provided during the entire useful life of the well through one of the following means:

    1051. Ownership by the water supplier of all land within 100 feet of the well;

    1202. Control by the water supplier of all land within 100 feet of the well via easements, lease agreements, or deed restrictions that appropriately limit use of the land; or

    1503. Wellhead protection, zoning, or other land use regulations that appropriately limit use of all land within 100 feet of the well.

    172(b) Public water supply wells shall be located to comply with the setback distances identified in Table I below.

    4051. This distance shall be reduced to 200 feet if facility Class I reliability is provided and shall be reduced to 100 feet if both facility Class I reliability and high-level disinfection are provided.

    4392. This distance shall be reduced to 200 feet if both facility Class I reliability and high-level disinfection are provided and if the applicant provides reasonable assurance that applicable water quality standards will not be violated at the point of withdrawal.

    4803. This distance applies only to shallow water supply wells (i.e., potable water wells that pump from an unconfined water table aquifer).

    5024. The following examples are of sanitary hazards that pose a potentially high risk to ground water quality and public health: active or abandoned mines; airplane or train fueling or maintenance areas at airports and railroad yards; concentrated aquatic animal production facilities; domestic wastewater collection/transmission systems; drainage or injection wells, oil or gas production wells, and improperly constructed or abandoned wells (i.e., wells not constructed or abandoned in accordance with this chapter); fertilizer, herbicide, or pesticide storage areas at agricultural sites, golf courses, nurseries, and parks; graveyards; impoundments and tanks that process, store, or treat domestic wastewater, domestic wastewater residuals, or industrial fluids or waste and that are not regulated by the Department; industrial waste land application areas other than those regulated by the Department; junkyards and salvage or scrap yards; pastures with more than five grazing animals per acre; cattle dip vats; pipelines conveying petroleum products, chemicals, or industrial fluids or wastes; and underground storage tanks that are not regulated by the Department, but are used for bulk storage of a liquid pollutant or hazardous substance other than sodium hypochlorite solution.

    6845. The following examples are of sanitary hazards that pose a moderate risk to ground water quality and public health: aboveground storage tanks that are not regulated by the Department, but are used for bulk storage of a liquid pollutant or hazardous substance other than sodium hypochlorite solution; fertilizer, herbicide, or pesticide application areas that are not under the ownership or control of the supplier of water at agricultural sites, golf courses, nurseries, and parks; railroad tracks; stormwater detention or retention basins; and surface water (the surface water setback does not apply to multi-family and private wells).

    781(c) New public water supply wells shall be located on their sites in such a manner that the wells are in an area free from, or least subject to, inundation with surface drainage and flood water; and to the extent practicable, new public water supply wells shall be located on their sites in such a manner that the wells are “upstream” from on-site or off-site sanitary hazards when considering the direction of ground water movement.

    856(2) The well construction regulations promulgated by the Department governing the construction of potable wells in delineated areas in subsection 87640A-3.041(1), 877F.A.C., shall apply to all potable wells constructed, altered, repaired, or abandoned in those delineated areas of the District.
