How far from the septic system must a water well be located?
According to 312 IAC 13-3-2 (Rules for Water Well Drillers) a water well must “use every natural protection” to maintain the quality of ground water encountered during well construction. The well must also be located “as far as practicable” from any known contamination source. Neither the statute nor the rules specify separation distances between new water wells and contamination sources. Many drillers try to observe the recommended distances in Indiana State Board of Health Bulletin PWS 2 (1983). Bulletin PWS 2 recommends a 50-foot separation between a septic tank and a domestic water well, and 100 feet between an absorption field and a water well. The Indiana State Department of Health regulates on-site sewage disposal and requires a new septic tank to be located 50 feet from an existing well. DNR does not regulate the distance between a new well and an existing septic tank.
