Does your well output seem low, despite the rain? The local weather forecast is calling for 7 days of rain. Well, well, well! That should fill ‘er up!

Isn’t it strange to think that rain doesn’t typically have an immediate impact on your well water? Unfortunately, it’s a common misconception that rain directly affects how much water is in your well. On average, over 95% of rainfall doesn’t impact your well at all, or even stay on your property. Say what?

Oddly enough, rainfall seeps into the ground and moves through the soil at an estimated rate of 10 feet per year. Since your well water aquifers are typically much deeper than that (sometimes hundreds of feet below ground), it could take more than a decade for todays water to impact your deep well.

Is this a good or bad thing? At Carolina Well and Pump we believe everything serves a purpose. Ground water and its slow movement is probably for the best. As the rainwater creeps through the soil, the water’s chemistry is altered, and it is purified from the majority of contaminates. It’s nature’s very own, purifying system.

For shallow wells, and aquifers relatively close to the surface, water levels do tend to fluctuate on a seasonal basis. However, at Carolina Well & Pump we wouldn’t recommend the use of a shallow well for the reasons mentioned above. Deeper wells mean less susceptibility to water contamination.

Here in North Carolina, the average well has a depth of 150 feet.
