A soil profile 8 ft. total depth, was excavated within the proposed absorption area. The excavation revealed no ground water to the depth of the profile hole. Soil Classification of the profile hole is as follows: 0" to 18" Dark organic soils and root zone w/ cobbles up to 24". 18" to 8' Tan colored sandy clay soils w/ cobbles. Jerome Gamba & Associates, Inc. performed percolation testing in the area of the proposed septic system. Three percolation test holes were excavated using a backhoe and hand shovel for the final 12" test pit. The Test holes were presoaked the night before the testing was performed. The results of the percolation testing are presented on the percolation results sheet. These results indicate a design percolation rate of 33 min/in.

The conclusions and recommendations submitted in this report are based upon data obtained from our field investigations of the proposed site. There is some possibility that the nature and extent of the Subsurface soil across the site may not have been discovered during our investigations and may require additional field work. If further excavation reveals conditions different form those described, our office should be notified of these findings as soon as possible.

On Monitoring/Observation Holes (test holes) it is the customer's responsibility to obtain the proper permit before the well is put to beneficial use (within one year) or the State may require the hole be plugged and abandoned. We will be happy to assist you whenever possible in filling out the appropriate well application. 3. The landowner is ultimately responsible for the plugging and abandoning of dry holes or replaced wells, according to State Rules and Regulations. Please contact us for details and/or prices. 4.
