😀 Real Property • Natural Rights PROP#240

Legal Definition

An owner of overlying land can take groundwater for reasonable use for almost any purpose—exporting is only allowed if it does not harm anyone else who has rights to the same aquifer. Most eastern states follow this rule.

Plain English Explanation

The reasonable use doctrine gives landowners the right to use groundwater beneath their property, but only in ways that are considered reasonable and won’t harm others who also have rights to the same water source.

In other words, if you own land sitting above an aquifer, you can pump and use that groundwater for almost any purpose, like drinking, farming, or industrial use, as long as you’re not being excessive or wasteful. The key here is that your use must be reasonable—meaning it shouldn’t negatively affect other landowners who also rely on the same aquifer.

One important limitation is exporting groundwater. You can take water and use it on your own property, but if you plan to pump it out and sell or transport it elsewhere, you can only do that if it won’t harm other people who have rights to the same water supply.

Most eastern states follow this reasonable use doctrine, ensuring everyone shares the groundwater fairly without one landowner draining it to the detriment of others.
