Quick Answer
Drilling costs for wells in bedrock soils are typically higher than for wells in sand soils, with costs ranging from $15 to $30 per foot for bedrock and $8 to $15 per foot for sand.
Drilling Techniques and Costs in Sand Soils
Drilling in sand soils is often less expensive and more straightforward compared to drilling in bedrock. This is because sand soils are softer and more easily penetrated by drilling equipment. The cost per foot for drilling in sand soils can range from $8 to $15, depending on the water table depth and the distance from the well to the drilling site. In general, a well drilled in sand soil may cost between $5,000 to $15,000 for a 100-foot depth.
Drilling Techniques and Costs in Bedrock Soils
Drilling in bedrock, on the other hand, is more challenging and expensive. Bedrock is harder and more difficult to penetrate, requiring more powerful drilling equipment and specialized techniques. The cost per foot for drilling in bedrock can range from $15 to $30, depending on the type and hardness of the bedrock. In general, a well drilled in bedrock may cost between $10,000 to $30,000 for a 100-foot depth. Additionally, drilling in bedrock often requires more time and labor, which can increase the overall cost of the project.
