To measure the static water level in a well, you need to determine the depth at which water naturally stands in the well when it is not being pumped. This is a key indicator of the water supply and health of the well.
Why Measure Static Water Level?
Understanding the static water level is crucial for several reasons. It helps you assess the well's performance and sustainability, understand seasonal water level fluctuations, and evaluate the impact of water usage over time. For property buyers, knowing the static water level can be a deciding factor in purchasing rural property.
Tools Needed for Measuring Static Water Level
To accurately measure the static water level, you will need the following tools:
- Electric Sounder: This is a device that consists of a probe connected to a cable with depth markings. When the probe hits water, it completes an electrical circuit, triggering a signal.
- Steel Tape: A steel tape measure can also be used, although it is less precise than an electric sounder. You may need to coat the end with chalk to mark the water level.
- Air Line: This method involves lowering a small diameter tube into the well and using air pressure to determine the water level.
Step-by-Step Guide to Measuring Static Water Level
1. Prepare the Well
Before measuring, make sure the well is at rest. Turn off the pump and wait for a few hours to ensure the water level has stabilized. This will provide the most accurate measurement.
2. Use the Electric Sounder
Lower the electric sounder into the well. Pay attention to the depth markings on the cable. When the probe reaches the water, the circuit will complete, and you will hear a beep or see a light flash. Note the depth marking at the top of the well casing.
3. Use the Steel Tape
If you are using a steel tape, lower it slowly into the well. When you think it has reached the water, pull it back up and check for the chalk mark. Measure the distance from the chalk mark to the wellhead to determine the water level.
4. Use the Air Line Method
Lower the air line into the well until it reaches the bottom. Use a gauge to pump air into the line. The pressure reading on the gauge will help you calculate the water level based on the depth of the air line submerged in water.
Interpreting the Results
The static water level is a vital piece of information when assessing a well's health. A declining static water level over time might indicate overuse or a decrease in the aquifer's capacity. It's essential to monitor this level regularly to ensure the long-term viability of your water supply.
Additional Considerations
When buying rural property in Wyoming, always research the well history and consult official well records. This will give you insights into the well's depth, yield, and any potential issues. Consider hiring a professional if you're unsure about measuring the static water level yourself.
