Rain Water Testing
Q:What is the quality of my rainwater?
While tank water systems provide very palatable water, they are particularly vulnerable to faecal pollution. Birds and other small animals, such as possums, leave their droppings on roofs and in gutters. These wash directly into the tank whenever there is a reasonable storm. Roofs, gutters and tanks are often inadequately maintained and cleaned. This neglect compromises the quality of the water collected.
When tanks are tested for contamination, they more often than not fail standard faecal pollution tests. In urban areas the presence of airborne contaminants (for example, lead from exhaust emissions) may make collected rainwater unsuitable for drinking.
In addition, because of the low buffering capacity of rainwater it is not uncommon so see elevated levels of copper and lead in rainwater that is distributed to the house via copper pipes. The following link provides information on Rainwater Plumbing.
