Section 7:9D-2.7 - Minimum distance requirements

(a) All new Category 1 and Category 2 wells shall be located at least five feet horizontally from a building or any portion thereof, except for a pump house.

(b) All Category 1 wells and components shall be located no less than the minimum distances prescribed as follows (all distances are in feet):

Component	Building sewer	Septic tank	Distribution box	Disposal field	Seepage pit*	Dry well	Cesspool	Fuel Storage tank
Well	25	50	50	100	150	50	150	25
Suction line	25	50	50	100	100	50	150	-
Water service line	5	10	10	10	10	-	25	-

*Note: The Department may reduce the 150-foot minimum distance between a new well and seepage pit system as a condition of well permit approval where the well casing is sealed into a confining layer separating the aquifer from the stratum of soil used for sewage disposal or where the well is constructed with additional casing.

1. Where gravel, limestone, or fractured, creviced or fissured rock formations are encountered and may pose a threat to the water supply, the local administrative authority may require a greater distance of a well from a subsurface sewage disposal system;

2. A well shall not be drilled within 20 feet of a wood frame building.

(c) All Category 2 wells shall be located no less than 25 feet from a fuel storage tank.

(d) Additional minimum distance requirements for any well may be required by the Department as necessary to protect groundwater supplies in areas of known contamination.

(e) The Department may modify the minimum distances in this section for individual well installations where it has determined that additional controls are necessary to protect water supplies.
