Quick Answer
A dry well can be identified by a decrease in water level, changes in water clarity or color, and the presence of sand, silt, or other sediment at the well's bottom.
Observing Changes in Water Levels
To identify signs of a dry well over time, start by monitoring the water level. Check the depth of the water every few months, ideally at the same time of day. A decrease of 1-2 feet (0.3-0.6 meters) in water level may indicate a drying well. If the well is consistently losing water, it may be a sign of an underlying issue with the well’s aquifer or surrounding geology.
Analyzing Water Quality
Changes in water clarity or color can also signal a dry well. If the water becomes cloudy, murky, or develops an unusual odor, it may indicate that the well is no longer receiving fresh water from the aquifer. In a dry well, the water may become more alkaline, acidic, or have an increased concentration of minerals. Take regular water samples to track any changes in quality.
Inspecting the Well’s Bottom
Finally, inspect the well’s bottom for signs of sedimentation. If you notice an accumulation of sand, silt, or other sediment at the bottom of the well, it may indicate that the water table has dropped. This can be a sign that the well is no longer receiving enough water to maintain a stable water level. Take a well core sample to assess the sedimentation and determine if the well is indeed dry.
