Mount Pleasant Well Service

Mount Pleasant Is as Close to Salt Water as Well Drilling Gets.

Mount Pleasant sits between the Wando and the Atlantic, and that position dominates every technical decision about a well here. This is the setting where getting the depth wrong has the most immediate and most visible consequence, because the shallow groundwater near the coast is frequently brackish and irrigating a garden with it will kill the planting.

Almost all the work we do here is irrigation. Mount Pleasant is comprehensively served by public water and there is no good case for a private drinking-water well. What there is a case for is taking substantial, established landscaping — the mature plantings that make properties here what they are — off a treated municipal supply through a long coastal growing season.

The engineering answer is depth and casing discipline. The productive water is in the deeper Floridan limestone; the trouble is in the shallow surficial zone above it. A well has to be cased through the brackish interval and screened or open only in the deeper unit, and that casing has to be properly grouted so the two never communicate down the annulus. A well drilled cheaply to a shallower depth may work for a season and then salt up. Once that happens it is not a repair, it is a replacement.

The chemistry you get from the deep unit is hard, often sulfurous water — characteristic Floridan. For irrigation that is largely workable, though hardness deposits on render and glazing and iron staining on pale hardscape are both worth planning zone layout around. Charleston County also sits inside a designated groundwater capacity use area, which matters for large systems rather than for a single household.
