Detailed Summary

Based on synthesis of well logs from the Black River Falls area, the most common subsurface sequence is a surficial sand or gravel layer, followed by a substantial thickness of sandstone, with occasional deeper transitions into shale or crystalline bedrock (granite). Sand layers generally extend to 20-40 feet, followed by dominant sandstone formations from roughly 40 feet to at least 105-225 feet. In some locations, deeper sections may encounter shale (around 225-242 ft) or granite (beyond ~250 ft). Casing is typically set to the base of the upper sand or through the unconsolidated overburden into competent sandstone. Typical residential wells (5-15+ GPM) are completed at 80-115 feet, while high-capacity wells (fire protection, etc.) may penetrate to or beyond 250 feet.
