Water wells draw directly from underground aquifers. Because no industrial power or treatment is required, they use far less energy, making them an excellent eco-friendly addition to a property. But it's possible that the water source could become contaminated, which is why well monitoring is essential. Here are answers to common questions on the topic.

Your Guide to Well Monitoring

What is a monitoring well?

Existing wells are used to analyze underground aquifers. Geoscientists can use them to assess the current water level and movement if there are concerns about drought, for example, or can test water samples to see if runoff from a farm or construction site has contaminated the water source.

Why are they important?

The underground aquifer is crucial to local homes and commercial infrastructure. If it fails, countless people and facilities could lose their water supply. Geoscientists can monitor the aquifer's overall health to determine if geological stress or construction near the aquifer is impacting it, for example. If there are concerns about output, they can then explore ways to reduce stress and preserve the aquifer. 

How are they chosen?

Well monitoring often uses existing, unused wells if they meet certain criteria. They must be in an ideal location that still has access to the groundwater, and the well casing must be in good condition. This ensures geoscientists don’t accidentally introduce contaminants to the groundwater during testing. 

They’ll also need complete information on the well to understand what aquifers it has access to. They can then accurately apply their findings.

What are the benefits?

Well monitoring can ensure people are aware of contamination before it affects their health. Identifying waterborne bacteria or high levels of chemicals will prevent GI issues and other health issues created by consuming this water. Professionals can also monitor the early impact of surface projects on the aquifer. If they see that a new construction project is putting too much stress on the aquifer, they can then explore less-invasive ways to complete the project.
