Our drinking water has been corrupted for a long time. Pharmaceuticals getting flushed down the toilet and the runoff from big agriculture are the two most obvious points of contamination but what we sometimes forget to consider is that people are poisoning our water supply on purpose. This is in fact the case! We are 80% water and healthy, clean drinking water is the foundation of a healthy body and lifestyle. We must start filtering our water. I will link a couple of different gravity-fed water filtration systems here as well as an environmental group that focuses on testing water among many other things.
