Placing a water well on your property is a task best left to professionals, but it's a good idea to understand a bit about proper well placement. Not only does this help you know why the well company chooses a specific location for your well, but also the knowledge allows you to provide some oversight to help avoid mistakes.
Septic and sewer
Most homeowners don't have an outhouse to worry about contaminating groundwater, but you will have sewer lines or a septic system. With a septic system, your well must be located as far from the drain field and septic as possible to avoid contamination. Even with sewer lines hooked to a municipal treatment system, there is always the concern of a broken line compromising your water well. Making a point to keep your water source as far from the septic or sewer is always a good decision.
The flow of water across your property can also affect well placement. For example, placing the well downhill from a neighboring farm can be a major issue, since fertilizer and pesticide runoff could end up in your drinking water. Generally, a well is placed upstream of any possible contaminants. This includes upstream of neighboring properties as well as things on your own property that could leach into your water source. This becomes less of a concern the deeper your well since deep wells bypass the use of more highly contaminated surface water.
You need to make sure the location of the well won't interfere with now or future plans for your property. For example, if you may want to expand your home at some point, ensure the well is placed far enough away from any expansion sites so it won't interfere. Even land you plan to leave undeveloped may have later concerns. You don't want the land on the sunniest part of your property since this is likely where you would plant a garden or orchard if you ever decide to do so.
Nearby water sources
Other water sources can also affect your well. A stream that flows through an industrial area could potentially pollute your well in the event of a flood. A saltwater marsh bordering your property could also ruin your freshwater source. The easiest way to avoid these concerns is to place your well far enough away from outside water sources so that there will be no intrusion from the possibly polluted source in the event of a flood.
