Water Level, Well Depth, Water Table

“What is well depth?”

Well depth is defined as the full depth from ground level to the solid bottom of your well shaft.

“What is the difference between the water table and static water level?”

Static water level or static or water level are synonymous terms and define the distance from ground level  down to the level of water in the well — at RESTING STATE.

“Resting state” means you are not pumping and haven’t pumped recently, and the well has filled back up to its maximum level. If you have pumped, then the water level, of course, is changing as the well fills back up to the static level. (The speed at which it refills – e.g. three gallons per minute – is called your “Recovery Rate”.)

Water Table is the level below which the pores in the soil and rock and saturated with water. The static water level in an individual well can be quite a lot higher or lower than the water table, depending on the shape of rock strata, their relative permeability and the hydrostatic pressure.

“How do I find the water level and well depth?”

You can check your well report. It would have both figures.

If you don’t have one, you can probably get a copy from your state government website, or your consumer protection branch, or your county health authority. (We can’t say which, for a particular area.)

Or the well company that drilled the well should have a record.

Or if you know how to do take the well cap off safely, you may be able to measure them yourself. Be VERY sure you are certain how to do this safely. Then you can measure the water level by lowering down a line with float and weight. Measure when the line goes slack.  Bring up and measure the length of line.  Do similarly without the float to get depth.  ONE CAUTION: the further down your water, the greater the chance you might get the line tangled in the submersible wiring.
