There are many reasons for drilling a new well. Whether your old one has been contaminated, you simply need a higher volume of water available, or you're building on a previously undeveloped site, the placement of your well can be critical. Incorrect placement can make the well unfit for human consumption, resulting in a waste of time and money.
Convenience is important, but creating a safe and plentiful source of drinking water is even more important. This guide lists four important characteristics and features of the land that you'll need to consider before deciding on the best location for your well.
1. The Properties of the Soil
Depending on how large your property is and how consistent the qualities of the soil are from one end of the lot to the other, you could find significant variation in suitability. For example, one area could be more gravelly and ideal for placing a well that will yield lots of water, while another area could be too silty and require special drilling techniques for a usable well.
Use whichever area offers the cleanest water, even if it’s not as convenient as other options.
2. Presence of Contaminants
Wells need to stay far away from potential sources of contamination. The more water you pump out of your well, the more strongly it will pull at surrounding water to fill the void. You need to make sure there's plenty of soil between your well and the contamination sources so that any pathogens, chemicals, or heavy metals will be filtered out.
Potential contaminants include things like sources of human or animal waste, junkyards, or surface water on your property. In addition, avoid agricultural areas such as cornfields because pesticides and herbicides can be dangerous.
3. Other Wells, Hills, and Low Spots
If your property already has a proven well, then it makes sense to want to drill nearby so you can take advantage of a nearly-identical situation for your new well. Unfortunately, that placement can cause more problems than it solves since the two wells will be competing with each other for the same water. For this reason, it's better to place your new well away from any existing ones.
You also want to avoid geographical features such as low spots in the property, since they can encourage contamination of your new well. Low spots, for example, could flood in winter, letting contaminated surface water seep down into your well. In addition, steep slopes often aren't a great choice either, simply because you may have to drill farther to reach the groundwater.
4. Availability of Groundwater
Aquifers are large underground water sources. Some aquifers are better than others are, depending on their placement, makeup, size, and so on. The larger the aquifer is, for example, the more water you can use on a daily basis. On the other hand, a small aquifer situated near the ocean could pull in saltwater to fill the vacuum if you pump too much out.
However, where you pump the water out from can also significantly affect your well's capacity. Some professionals use a technique called fracture tracing to find geologically ideal spots for well drilling. These spots are fractures in the underground rock that makes up the aquifer. Using this technique can be a big help if you need a high-volume well for irrigation.
After checking your property for these four characteristics and features, you can start to get a grasp on which sites are actually suitable for well drilling. After that, you can begin to weigh which spots are safe, ideal for a well, and convenient. Remember that the closer the well is to your house, the less you'll have to pay to pipe the drinking water into your home.
