The following facts were discovered during the course of this investigation: • The dye that was observed in the cistern on the Bachrneier/Chalupsky property does not match the chemical profile for the dye that was introduced into the "observation" pipe for the distribution box on the Muehlstad property; • The observation pipe does not discharge into the distribution box as thought, but simply marks the location of the distribution box; • The drain field at the Muehstadt residence was installed consistent with the rough sketch that was prepared prior to the installation of the drain field; • The termination point of the drain field on the Muhlstadt property is 21 feet from the fence line, the required setback distance is 10 feet • All drain lines that were inspected, terminate in the rock field; • The rock field does not extend into the Bachmeier /Chalupsky property; • No additional drain lines or rock fields were discovered along the property line; • Due to soil and weather conditions the site soils were saturated; and • No evidence of disturbed native soils were observed in the pictures provided by the Bachmeier /Chalupsky's that would indicate that a pipe or drain field was installed onto their property from the Muehlstadt property is evident. Based on the facts discovered during this investigation the following conclusions can be made: • The yellowish hue /dye that was observed in the cistern at Bachmeier /Chalupsky residence was not due to the addition of the dye tablet into the "observation" pipe. • Neither drain field pipe not drain field rock extend from the septic system on the Muehlstadt property to the Bachmeier /Chalupsky property. • Untreated sewage is not being discharge from the septic system on the Muehlstadt property directly onto the Bachmeier /Chalupsky property. • Due to tight soil conditions, and drainage that slopes toward the drain field, this site will experience a high water table after heavy rains.
