Water Testing & Yield Testing

We can draw a sample of your borehole/well point water and have it analyzed for bacteria, physical characteristics (such as pH and hardness), the presence of organic and inorganic chemicals, radon, lead and numerous other attributes. We can also test the quality of the water from your well. This is especially important if your well is located near an area of regular pesticide use (e.g., farm; nursery) or near an industrial area.

We only make use of certified laboratories.

Determining the yield of a well involves a test to see the balance between the maximum amount of water that can be pumped out of the well and the amount of water that recharges back intothe well from the surrounding ground water source.

The test requires the continuous pumping of the well for an extended period of time. During the pumping period, measurements are made of 1) the rate at which water is being pumped out of the well and 2) the distance the water level is lowered in the well as a result of the pumping, known as the drawdown. Balance, or equilibrium, is achieved when the water level within the well stops dropping for a given discharge rate. Once equilibrium is achieved, less pumping results in less drawdown. Water well professionals rely on the yield pump test to set the well pump at the correct level.

Determining the safe yield of a well is an involved process. In most cases, well owners should contact a water well professional, who will have the specialized equipment needed. For a new well, a yield test can be performed immediately after the drilling has been completed.
