When people call me to ask what water filtration system I recommend I always look at their local water report before making any recommendation. There are several reasons for this.
First, what is the source of the water? If it is a river with cities upstream then there will be sewage present in the water and therefore trace amounts of pharmaceuticals. And while USEPA has not declared these to be a health issue for humans they are known to have harsh impacts on fish. Here’s one article about the impact of anti-depressents on fish. It changes their behavior dramatically:
So if pharmaceuticals affect fish what makes us think they don’t affect people whose drinking water contains them. Actually numerous studies in Europe shows that the levels of pharmaceuticals present in drinking water do affect human cell function. See my website http://www.cleanairpurewater.comfor articles on this topic.
What can you do to protect yourself? As of today the only technoloogy proven to remove pharmaceuticals from water is reverse osmosis. You can learn about the reverse osmosis system that I offer here: https://cleanairpurewater.com/kitchen_water_filter.html
However you also shouldn’t just assume that your water has pharmaceuticals present. Study your water source and you can even call your water company and ask them. Always check your local water report before buying a filter and always buy the filter that is known to remove the contaminants in your water. Otherwise you’ve just wasted your money.
