Regarding USDA, what are the minimum distances between the well and septic?

For USDA loans, the minimum well and septic distance must comply with HUD, state and local guidelines. FHA states "For existing properties, FHA requires that a domestic well be located a minimum of 100 feet from the septic tank's drain field and a minimum of 10 feet from any property line. Should state or local regulations require greater distances, those distances must be met."http://www.rurdev.usda.gov/co/pdf/GRHexhibitD3-FY06.pdf -- USDA Guidelinehttp://portal.hud.gov/hudportal/documents/huddoc?id=DOC_16736.doc? --FHA requirementIf you have any further questions, please feel free to call on me at 281.841-1723.

USDA and FHA use the same guidelines :HUD - For an existing property, what are the minimum distances allowed by FHA between a well and a septic tank? For an existing property, FHA requires that a well be located a minimum of 100 feet from the septic tank's drain field and a minimum of 10 feet from any property line. If State or local laws require greater distances, those distances must be met. If State or local law permits distances that are less than those prescribed by FHA, the property may be considered eligible provided that the lender submits evidence in the case binder that the property is in compliance with the applicable local or State distance requirements and meets the conditions stated below: 1. Domestic Well from Septic Tank Drain Field: FHA will recognize State/local distance requirements provided they do not allow for less than 75 feet of separation.2. Domestic Well from Property Line: FHA will recognize State/local distance requirements provided that the well is not within 10 feet of any roadway or the property line of other than a single-family residential property, i.e., the well cannot be within 10 feet of a commercial, industrial, or multifamily building. If the appraiser notes on the appraisal report that the minimum distances have not been met, the lender must obtain satisfactory evidence from a qualified party that the distance requirements (between the two systems, and from the well to the property line) have been met.
