Well Drillers Near Friendship, Wisconsin

Typical geology in the Friendship, Adams County region is a sequence of unconsolidated sands, interbedded with minor sandy clay, gravel, and occasional clay, overlying sandstone at greater depths. Most domestic wells are constructed entirely within these unconsolidated sand and gravel units.

Detailed Summary

Based on the sample of well logs from Friendship and surrounding areas in Adams County, the most representative geological sequence begins with a surface sand layer (commonly extending 25–35 ft), underlain by sandy clay or clay (when present) for roughly 5–15 ft, then transitioning to thick zones of sand or sand/gravel mixtures typically continuing to the base of the commonly drilled interval (60 to 105 ft). In deeper, high-capacity wells or rotary wells, sandstone is frequently encountered beneath these deposits. The water table (static level) usually sits between 10 and 35 feet below ground. A standard residential well seeking 5–15+ GPM yield is most often completed at about 65–75 feet, with some higher-capacity or rotary wells going deeper, commonly to 100–105 feet, with screens set in the deeper sand or initial bedrock zones.
