§ 23B-9b. Well sealing.

Latest version.

In addition to well sealing requirements specified within state well standards bulletin 74-81 and bulletin 74-90, all wells shall be sealed to minimize the risk of introducing shallow water contamination into a deep aquifer. The annular seal shall be of sufficient depth to exclude water above the fifty (50) foot depth. Unless otherwise specified by the health officer the seal shall be extended five (5) feet into the first consolidated formation encountered below fifteen (15) feet to a maximum required sealing depth of fifty (50) feet.
