Free Water Test For Your Home or Business

Thank you for visiting our free water test page!

Annual well water testing (yes, EVERY year for well owners!) and municipal water testing (if you are getting your water supply directly from your city or town) is crucial to ensuring the water in your home or your business is safe and clean—clean is being free from ALL contaminants! Capital Well Clean Water Center serves all of New Hampshire and the areas of Vermont and Maine which fall along or are close to NH’s border.

Our FREE on-site water test includes:

If you would like us to add-on Bacteria, Nitrates, Arsenic, Radon, Lead, Uranium, PFOS – PFOA, MTBE, or any other tests, please note this in the form below or when you call to schedule your free water test and we will tell you what the cost will be.

Why is Water Testing Important?

Many minerals and chemicals such as nitrates, radon, arsenic, lead, and chlorine are invisible to the naked eye. While the presence of excess iron, for example, is noticeable because it presents a foul odor and metallic taste, some other contaminants are completely odorless and tasteless. In other words, when it comes to the purity of your water, you cannot always trust your senses. You can, however, rely on the clean water professionals at Capital Well who have the experience and expertise necessary to test your well water for contaminants of all types. But we don’t stop there. The purity of New Hampshire’s water is our primary concern, and we’re dedicated to providing only the best, most reliable water filtration and treatment services to help your family stay healthy and happy.

Why Capital Well Clean Water Center for Your Water Test?

Many homeowners and property owners assume the role of water testing themselves, using kits that can be found in hardware stores and online. This can be dangerous, as most kits are incapable of testing for every possible impurity in your water systems. Further, once impurities are found, the process of finding the root cause of contamination is a complex process that requires water science professionals who are well versed in advanced water filtration and water treatment and testing techniques.

Whether you use a well or your home is on a public water system, the New Hampshire Department of Environmental Services also recommends annual well water testing, while the Centers for Disease Control and Prevention suggest a general well check every spring to make sure there are no mechanical problems that might allow contaminants into your water.

The state of New Hampshire has an excellent fact sheet on water well testing that you can read at the link, and you can visit their website for more information at
