What can I find in my water?
For town supply the councils are under government regulations to keep the water quality to a certain level. Unfortunately, councils also have to put chlorine in the water to keep the pipes clean, and also they can only get the water to a certain quality with a limited budget and a long way to get the water to your property. Once the water arrives at your gate you don't need the chlorine. Below is a list of common contaminants possible in water and with possible related issues.
