   What Are the Possible Sources of Contamination?

During sampling -
ensure that you don't contaminate the water when you are collecting the sample.

Problem with the well -

surface water may be getting into the well through poorly sealed joints, missing or damaged sealant around the casing or an ill-fitted cap.

Water source contamination -

contaminated water seeping into the aquifer through abandoned wells or from poor land use practices such as a failing septic system.
