on inspection of home built in 1945 dicovered that septic tank
was too close to well, approximately 15 feet seperating the two-
age of either is unknown, best estimate is septic is original and well 30 years old- well is 290 feet deep

coliform tests have come back negative, but still have lingering doubts and questions

house has been vacant for about three months, how does this affect the coliform tests?

does depth of well( 290 feet ) provide protection from contaminants?

options to correct problem, rather than drilling new well

any suggestions are greatly appreciated
