Crack-Water Drilling

It depends on the connectivity and productivity of the fracture network the well intersects. Some crack-water wells produce excellent, consistent yields; others produce marginal flow. Wells drawing from the Spokane Valley–Rathdrum Prairie Aquifer's sand and gravel sediment tend to have more predictable yields. An experienced driller who knows the local geology can identify which type of well is likely on your site and plan the bid range accordingly.

Not with precision. Drillers use geological maps, surface expressions, and nearby lithology logs to make an informed assessment, but the exact location and productivity of fracture zones cannot be confirmed until the drill reaches that depth. This is one of the primary reasons why worst-case scenario bidding is especially important for basalt-zone properties — the depth needed to intersect a productive fracture may be greater than initial estimates.

Water from fractured rock can carry elevated levels of naturally occurring minerals depending on the rock composition. All wells — including crack-water wells — should be tested for bacteria, nitrates, minerals, hardness, and pH before use. In Idaho, water quality documentation is also required for bank loans and most property transactions.
