Current through Reg. 50, No. 138; July 16, 2024
(1) New potable water wells shall comply with
				the minimum construction standards contained in Rule
				 62-532.500, F.A.C. Additional
				requirements may be assigned by the permitting authority relative to depth
				restrictions, location of screened or open hole interval, and length of casing
				where warranted by local specific information.
(2) Methods for constructing new potable
				water wells shall be limited to rotary drilling, boring, or other method
				specifically approved by the permitting authority pursuant to subsection
				 62-524.700(1),
				F.A.C., which meets the water well construction criteria in Rule
				 62-532.500, F.A.C., except as
				required below.
(a) Well casing and liner
				pipe shall be new, free of breaks, corrosion and dents, straight and true, and
				not out of round. Welded or seamless black or galvanized steel pipe or casing,
				or stainless steel pipe or casing, or approved types of nonmetallic pipe shall
				be used for well casing or liner pipe.
(b) Solvent-bonded couplings shall be
				prohibited in areas with known ground water contamination which includes
				solvent components.
(c) To prevent
				the interchange of water and loss of artesian pressure, contaminated,
				unconfined ground water intervals shall be sealed off prior to drilling through
				the underlying confining interval. Uncontaminated, unconfined ground water
				intervals shall be sealed off or otherwise protected prior to drilling into
				deeper, contaminated ground waters.
(d) For any well casing installed in a bore
				hole, the annular space shall be filled from bottom to top with not less than a
				nominal two inch thickness of neat cement grout.
(e) A concrete pad measuring three feet by
				three feet by four inches shall be constructed around the elevated portion of
				the casing so that the casing is centered in the pad to prevent soil erosion
				and seepage of surface contamination into the annular space.
(f) A minimum elevation of one foot of casing
				above land surface shall be required.
(g) A raw water tap shall be provided to
				allow sampling of the well before exposure to storage or treatment.
(h) The well casing shall be visibly and
				permanently marked above the land surface with the latitude and longitude and
				the permit number issued by the permitting authority for that well.
(i) To the extent practical, potable water
				wells shall be located outside an area delineated under Rule
				 62-524.420, F.A.C.
(j) Where the source of contamination and the
				direction of ground water flow are known, in an area delineated under Rule
				 62-524.420, F.A.C., to the
				extent practical, potable water wells shall be located upgradient of the
				source.
(k) New potable water wells
				shall be located on ground least subject to inundation.
(l) Any new potable water well constructed
				within a delineated area that does not meet the construction standards of this
				section shall be abandoned and plugged in accordance with Rule
				 62-532.500, F.A.C., and
				applicable water management district rules.
