Who should you trust with something as important as water quality?

NO ONE!
If I can offer one situation to best express my intention and desire it would be of an experience I had while vending at an environmental trade show in Raleigh, NC. I was at the event primarily to market water conservation products for a business I started in 2003; AquaPro Solutions llc.
I had decided to display our H2O Easy water filtration products to help introduce the new WaterGenie to the regional market. I was approached by a middle aged woman from North Carolina named Kathy, inquiring about the capabilities of the WaterGenie. We'll not disclose the city in NC where she lived as I have no desire to enter into a liable suite with any municipality, but trust me it is a large city/county in the heart of NC.
Our conversation began in a typical way but didn't stay that course for more than a couple minutes. Kathy was much more serious with her questioning than usual; It was clear that she had a sincere distrust. As I attempted to carry the conversation as sensitively as I could she became more open about her concerns. Kathy had experienced and lived through a devastating bout with breast cancer, and was continuing to experience health problems. She discovered that she had mercury toxicity. She had spent several months trying to determine the source of her exposure, which turned out to be the municipally treated water supply. As soon as this became evident she had her two young children and husband tested and all were found to have elevated levels of mercury. Kathy was certain this condition had caused her cancer and continuing health concerns.
I was appalled to find out that she had attempted to seek assistance from the water purveyor and bring the problem to light but her concerns were dismissed by county officials; the municipality would not assume any liability for her condition or acknowledge in any way the water may contain high levels of Mercury; and furthered the insult indicated that she could choose not to drink the water!
After about an hour of heartfelt communication I proposed to have an H2O Easy system installed in her home at no expense to her family until she decided the system performed to her satisfaction. She agreed, two weeks later I had performed the installation and after six months and several lab tests to verify the water quality, Kathy offered to pay for the system in full, including installation costs; which we declined to accept.
Kathy and her family have sense moved out of state and purchased a new H2O Easy WaterGenie system for her new home.
I often reflect on this experience, which continues to be an enduring reminder of why I do what I do, and why I will continue to do it as long as I can help others out of bad situations, like Kathy's.
My advice; never take for granted that someone else is looking out for your best interests, and always remember, municipalities are businesses not people; they don't put your health and wellbeing ahead of their own unless it serves their purpose. They do what they do because the law requires them to; and most do the minimum
they possibly can. This means using very dangerous chemicals rather than healthy alternatives because chemicals are the least expensive option available. It is up to you to take responsibility and be proactive when it comes to the food you eat and the water you drink, bathe in and cook with. I don't want you to trust me because I say you can, I want to earn your trust, gain your respect and deserve your business. 

That's the H2O Easy way.
Sincerely,
