Detailed Summary
Based on a synthesis of well records from Medford and nearby towns, the most common geologic profile is: 5–35 feet of brown clay or hardpan (occasionally sandy), often grading to some sand/gravel seams from ~20–40 feet, then transitioning to thicker gray and blue clays with some grit and minor stones extending to 60–80 feet. Granite bedrock (gray, red, blue, or black) is consistently encountered from about 75–85 feet, continuing to total depth. Residential wells for 5–15+ GPM are typically finished just into, or immediately above, the granite, at 40–120 ft. High capacity wells may extend further into the granite as needed. Water is typically first encountered within the upper sandy/gravel layers or at the clay/granite interface.
