Flouride In Water


Top 10 States With the Most Toxic Tap Water:
1. California
2. Wisconsin
3. North Carolina
4. Florida
5. Texas
6. New York
7. Nevada
8. Pennsylvania
9. Ohio
10. New Mexico 

What is your water situation?

"With 40 percent of U.S. community water systems in violation of the Safe Water Drinking Act, which sets drinking-water quality standards and is directly linked to the Clean Water Act, 23 million people received low-quality drinking water. "

"North Carolina- In this state, 6.1 million citizens were exposed to 59 contaminants that exceeded the EPA's limits. Nitrate, which can have a negative impact on kidneys, blood, the heart and the reproductive systems, was the most common contaminant.

The suspected carcinogen enters water through fertilizer runoff, leaching septic tanks and erosion of natural deposits. Bromodichloromethane showed up in amounts that exceeded health limits in 373 communities, exposing 5 million people to potentially dangerous amounts of the toxic compound."

Are You Drinking Contaminated Tap Water?

Depending upon which contaminants you are trying to remove and your price point, the alternatives vary greatly. To just remove chlorine is probably not sufficient, since many excreted and flushed medications are in city water. Apparently, they do not remove medication from city water. Plus, some do/don't remove fluoride. 

So, distillation is the most effective, but not really home use friendly. Reverse osmosis probably does about the same job, and has a lot of filter issues and cost, maintenance and installation. Might be overkill, if you are on healthy well water. But, if you have your own water tested, or read the government's city water reports, you could gauge more accurately which type of chemical removal you need.

I really don't believe that most home water filtration systems remove BPA and Phthalates, unfortunately. My understanding is that an RO system may. Yes, this seems to indicate RO does remove phythalates:

Seems you need a carbon filter to remove BPA...
and others report no filtration system will remove the BPA and that water is a minor source of BPA compared to other contaminants in our food supply with BPA. 

Environmental Toxins in Drinking Water: Phthalates 
- Phthalates are found in our drinking water, air, and food all over the world.

Researchers estimated that more than 75% of the U.S. population is exposed to phthalates. Starting as early as the 1950s, scientists have published research findings in peer-reviewed academic and science journals on human and animal exposure to phthalates and their wide variety of health problems, as follows:
1. Infertility (especially among men)
2. Cancers (e.g., liver, breast, prostate, testicular, colon)
3. Autoimmune diseases (e.g., lupus)
4. Fertility problems (e.g., low sperm count, poor mobility of sperm, DNA damage in sperm, lower testosterone level, and ovarian dysfunction)
5. Obesity, resistance to insulin, and diabetes in men
6. Smaller testes and smaller genitals on average among male babies exposed to phthalates in mothers' wombs
7. Asthma
8. "Feminization" of male fish, frogs, and other amphibians living in phthalates-contaminated
rivers in the wild
