Waterborne illnesses have two main causes:

1. Pollution e.g. dangerous levels of chemicals, nitrates or heavy metals in the water supply due to industrial pollution or the over-use of agricultural chemicals.
2. Dirt & Contamination - Bacteria, viruses and parasitic organisms invisibly contaminate the water and cause disease. Much of this contamination is through water coming into contact with animal and human waste. Just one gram of faeces can contain up to 100 billion microbes.
