Shallow Well vs Deep Well in Northeast Florida

Short answer:

A shallow well in Northeast Florida draws from the surficial aquifer at 40 to 80 feet, is less expensive to install, and typically carries iron that stains driveways and stucco. A deep well drills 200 to 500 feet into the Floridan aquifer and delivers iron-free water with more consistent yield. Deep wells cost more up front but solve the staining and drought-sensitivity problems that shallow wells cannot.

How to choose for your property

The decision usually comes down to three questions. First, is this well feeding household water or irrigation only? Whole-house use points toward a deep well. Second, is staining acceptable? If the property has decorative concrete, stucco, or vinyl fencing the homeowner does not want to see stained, deep is worth the extra cost. Third, what is the long-term ownership horizon? Deep wells almost always pay back on properties held for 10+ years through reduced pump replacements and no staining maintenance. Our residential well and pump page and the county-by-county depth breakdown cover this in more detail.

Frequently asked questions

Can I convert a shallow well into a deep well? +
No. A shallow well is drilled to a specific depth and cannot be extended to the deeper Floridan aquifer. Going from shallow to deep requires drilling a new well. The old shallow well is typically capped or repurposed for irrigation-only use.
Will a shallow well run dry in a drought? +
It can. Shallow wells draw from the surficial aquifer, which is more sensitive to prolonged drought and heavy neighborhood pumping demand. Deep wells drawing from the Floridan aquifer are far less affected.
Are shallow wells still worth installing today? +
Yes, for the right application. Irrigation-only wells, budget-constrained residential projects, and locations where the surficial aquifer produces acceptable water quality can all justify a shallow well. WaterCare evaluates the parcel before recommending either option.
What does a deep well typically cost more to install? +
Deep wells require more casing, deeper drilling, and larger pumps, so installation cost is meaningfully higher than a shallow well. WaterCare gives itemized estimates so customers can weigh both options against long-term water quality and yield.
