LAC 56:I.315. Location in Relation to Possible Sources of Contamination

A. The horizontal distance between any water well and any possible sources of contamination shall be as great as possible but in no case less than the following minimum distances. Possible Sources of Contamination | Minimum Distance (in feet) Septic Tanks | 50 Storm or Sanitary Sewer | 501 Cesspools, outdoor privies, oxidation ponds, subsurface absorption fields, pits, etc. | 1002 Sanitary landfills, feed lots, manure piles, solid-waste dumps and similar installations | 100 Another water well | 253 Drainage canal, ditch, stream, pond or lake | 504 1This distance may be reduced to 30 feet if the sewer is of cast iron with leaded joints or schedule 40 plastic pipe with water-tight joints. 2For domestic water wells, this distance may be reduced to 50 feet. 3This minimum distance requirement does not take into consideration the effects of interference from pumping nearby wells in the same aquifer. 4Horizontally measured from the water edge to the well at the highest water level which may have occurred in a 10 year period.
