It is well owner's responsibility to have their well water tested regularly. All wells should be tested at least three times a year or every three to four months. This will provide the owner with a seasonal picture of the quality of the water in their well.
Testing drinking water is an important part to having safe water. For information on:

Sources of Drinking Water
There are three main types of water well: drilled wells, bored/dug wells, sand point wells.
If you own a well, you can obtain a free copy of the Best Management Practices: Water Wells from you local health unit office. It explains well components, maintenance, new well construction requirements, and procedures for unused wells. It also has step-by-step instructions for well disinfection and how to interpret your well water sample results.
Some people may even get their drinking water from a surface water source. Surface water is any source of water that is open to the atmosphere and is subject to runoff from the land. This includes lakes, streams, rivers, ponds and springs. Because these sources are open to the environment and subject to runoff, it is likely that the water will contain micro-organisms, such as bacteria, viruses, and parasites that can cause illness. The Health Unit does not recommend that surface water be consumed unless it is treated through proper filtration and a disinfection system.
