New Hampshire is known as the Granite State, with beautiful scenery, lots of green space, and many opportunities for outdoor recreation. Most people expect that the water is clean and clear throughout New Hampshire. In the past couple of years, there has been on-going reporting on the PFAS contamination in the southern  and seacoast areas of the state. There are more sites with different contaminants in other areas of the state, as well as naturally occurring chemicals, contaminants and poison-like materials in the water.  At Capital Well Clean Water Center, we care about your health and  believe everyone should have clean, healthy water. We stay on top of all the water issues in New Hampshire and will continue to compile a list of links to articles  from various sources which are educational and informative.
