A step-by-step guide to drilling a water well: permits, choosing a licensed contractor, what to put in the contract, what a good survey includes and how to test the water.

Groundwater can be at the surface or hundreds of feet down. What controls water table depth, how it varies by US region and season, and how to find local numbers.

Groundwater ranges from fresh to highly saline, and salinity often rises with depth. What USGS data show and how to improve your odds of drilling into fresh water.

Choosing a well site means balancing geology, setbacks, permits and drilling cost. A step-by-step guide for rural landowners, with a checklist.

Water dowsing, electronic water detectors and professional geophysical surveys compared honestly, with what the USGS and EPA say about each approach.

Groundwater detectors use resistivity probes, long-range modes or both. Here is what the science supports, what is a manufacturer claim, and how to use one responsibly.

The most reliable way to find underground water is to stack evidence: well records, geology, a survey and a licensed driller. Here is how each method compares.
