Here's a deep question... do you know how to protect local well water?
Municipal drinking water can come from a wide range of possible sources including surface water (lakes, rivers, streams) and ground water (aquifers). In London, almost all of our 100,000+ water customers are serviced by municipal drinking water which comes from the Great Lakes (Lake Huron and Lake Erie). However, in addition there are a small number of homes and businesses that receive their drinking water from ground water sources through wells. As a result, it is critical for water users of today and the future to not only conserve water but to protect it to ensure it is safe and reliable. The best way to protect these sources of water is considering them on a watershed basis since water crosses many boundaries and jurisdictions.
Did you know?
- There are 14 sub-watersheds within the City of London’s boundaries.
- London’s emergency water supply is from two well fields.
- Assess the role your well plays on your property and residence. If the well is not used as your sole source of drinking water then consider having it properly decommissioned. There is funding available to financially subsidize the decommissioning of your well.
- Disinfect your well system twice a year. Afterwards, conduct a water test to ensure the water quality is of the highest standards possible.
- Test your water annually for coliform bacteria, nitrates, and other contaminates.
- Practice water conservation so you do not overload your system.
- Keep potential contaminants a safe distance (at least 30 m or 100 ft) away from the well.
- Minimize or eliminate the use of toxic materials inside and around your house such as toxic household cleaners, pesticides, and herbicides.
- Use phosphate free dishwashing detergents.
- Use natural alternatives for chemical fertilizers such as compost.
- Install backflow protectors on all outdoor faucets.
- Slope the well area so that surface runoff drains away from it.
- Install a locking well cap or sanitary seal to prevent unauthorized use or entry.
- Never dispose of wastes in dry or abandoned wells.
- Perform monthly inspections to check for visible problems such as cracks, corrosion, a broken or missing well-cap, and the settling and cracking of surface seals.
