*****************************************************

After flooding, well owners should take actions to:

  • make their water supplies safe for consumption; and
  • protect the groundwater resource used as a source of drinking water.

When a water supply well has been affected by flood waters, the water within a well may be contaminated with waterborne pathogens (germs) that can cause serious illness in humans and pets. The water in the well can also be contaminated by debris, fuel oil or other chemical products released during the flood.

During flooding, the ground around the well may also erode, possibly creating unsafe conditions or a pathway for surface water and contaminants to enter the well.  In other cases, the electrical wires attached to the pump in a well may be damaged risking electrocution.  Therefore, well owners should exercise extreme caution approaching their wells, especially older, large diameter dug wells after a flood.

If a well owner believes that the well has been contaminated by flood water, the well owner should discontinue using the water in the well for drinking and cooking purposes and use potable water from another source.

Under the Wells Regulation [R.R.O. 1990, Regulation 903 (Wells) as amended made under the Ontario Water Resources Act, R.S.O. 1990, c. O. 40]:

  • the well owner must maintain the well to prevent the entry of surface water and other foreign materials. 
  • if laboratory analysis of water samples from the well show the well is producing water that is not potable, then the well owner must contact the local Medical Officer of Health (MOH) and follow his or her advice or immediately abandon the well.  As an alternative to contacting the MOH, the well owner could contact the Director appointed under the Wells Regulation at 1-888-396-9355 (WELL) for written consent not to abandon the well.

To bring a well back into service safely, a well owner should consider contacting:

  • a qualified registered professional (e.g. professional engineer or professional geoscientist) or a licensed well driller to evaluate and service a drilled well;
  • a qualified registered professional or a licensed well digger to evaluate and service a dug well;
  • a licensed pump installer and, if necessary a certified electrician, to evaluate and service the well pump. 

Note - A residential private well owner can work on and disinfect his or her own well.  However, there are some safety considerations when working on a well and many technical steps needed to properly clean and disinfect a well.  Therefore, the well owner should consider retaining the services of a qualified professional or qualified technician as noted above.

If the well structure, pump and surrounding ground surface have been repaired or are deemed sound, the water in the well should be pumped and disinfected by a licensed well technician as outlined in Chapter 8: Well Disinfection of the Water Supply Wells – Requirements and Best Management Practices manual published by the Ministry of the Environment and Climate Change, revised 2015. 

The Well Disinfection chapter of the manual provides the following steps to properly disinfect a well:

  • Initial steps which include:
    • following sanitary practices
    • removing any debris from a well
  • Thorough flushing of the well
  • Treatment with a properly prepared chlorine solution, i.e. “shock” chlorination
  • Discharge of heavily chlorinated water from the well and the plumbing
  • Collection and analysis of water samples for indicator bacterial parameters

The Well Disinfection chapter of the manual is available at the following website: https://dr6j45jk9xcmk.cloudfront.net/documents/4965/h-wwbmp-chapter-8-well-disinfection-april-2015.pdf

A synopsis of the Well Disinfection chapter for interested well owners is provided in the Wells Regulation – Well Disinfection 2011 technical bulletin and is available at the following website: https://www.ontario.ca/page/technical-bulletin-wells-disinfection.

Flood Warning Update, Rideau and Ottawa Rivers

Flood Warning Extent Reduced

May 15, 2017 – Water levels have continued to recede over the weekend and are not expected to be affected significantly by rain forecast for later this week. This has led to a reduction of the coverage of the Flood Warning.

The Flood Warning is now limited to the upper Tay River where outflow from Bobs Lake has continued but there has yet to be a significant drop of the water level. Several properties around Christie Lake are still flooded. Sections of the Christie Lake North Shore Road has been under water for several days.

Flow of the Tay through Perth is declining slowly at 1 to 2 centimetres (cm) per day as water passes through from Bobs Lake. Some flooding has occurred in Stewart Park and in and near Last Duel Park in Perth.

Not as much rain as was forecast fell over the weekend. Little to no increases in levels occurred in the Rideau watershed or in the areas the RVCA monitors on the Ottawa River - Lac Deschene, Petrie Island and Boise Village. These areas are no longer under Flood Warning status as levels decline by about 10 cm per day.

The water level on the Long Reach of the Rideau River has dropped below the flood level for the access road to Hilly Lane. Flood waters have fully receded at all the rest of the susceptible areas on the Long Reach.

Rideau Canal reservoir lakes, Big Rideau, Upper Rideau and Wolfe, have all been declining with Upper Rideau dropping below the Full Supply level today.

Conditions around rivers and lakes are still hazardous with water levels that are relatively high. Everyone, especially children, are advised to stay away.

The public is encouraged to tag us or share photos of water conditions in their area at RVCA Facebook (RideauValleyConservationAuthority) and Twitter (@RideauValleyCA).

Conservation Authority staff will continue to monitor conditions and will issue updates as warranted.
