Why assume water is what we hope it to be?

Water is the lifeblood of all existence. Whether it is used for drinking, cooking, heating, bathing or swimming, we all rely on clean water. If you and your family are supplied with water from a private well, it is your responsibility to ensure its safety and quality. By having EAI Analytical Labs test your water, you will be empowered with the knowledge of what contaminants are present in your water supply and what you can do to protect the health of you and your family.
