Municipality
The Township of Ashfield-Colborne-Wawanosh provides clean, safe drinking water to more than 262 people in the Dungannon area. Your positive actions can help to keep that water safe and clean.
Impacts of Plans
Your local source protection committee, for the Maitland Valley and Ausable Bayfield areas, has prepared drinking water source protection plans. The Province of Ontario has approved these plans which took effect in April of 2015.
These plans help to keep your drinking water safe. Plan policies may require action from you if you are located in municipal wellhead protection area (WHPA) zone A, B or C. Please click on the map link for wellhead protection areas.
Information
Current information is available by visiting the Assessment Reports section of this website. The following is for local information purposes and may be subject to change.
Your Community Well System
The following is a description of the Dungannon well system:
Well Description
- There are two municipal wells located in Dungannon.
- Location: The municipal wells are located at the east edge of the hamlet of Dungannon in the Township of Ashfield-Colborne-Wawanosh.
- The wells and wellhead protection areas are located in the Maitland Valley Source Protection Area.
- Dungannon Well was constructed in 2008.
- Well One Depth: 77.7 metres
- Well Two Depth: 87.2 metres
Where Does the Water Come From?
The two municipal wells draw groundwater from an aquifer. Aquifers collect water underground much like a sponge collects water. The municipality draws that water from underground through the municipal well.
How is the Water Treated and Distributed?
Treatment:
The Township of Ashfield-Colborne-Wawanosh uses chlorination and iron sequestration to treat the water. Operators must adhere to strict requirements for the treatment, testing and distribution of drinking water specified in the Safe Drinking Water Act. Ontario Drinking Water Quality Standards require compliance.
How is the Drinking Water Source Protected?
Ontario’s Clean Water Act, 2006 was created to protect drinking water at the source as the first of several barriers of protection. Other barriers of defence include monitoring, distribution, and the three Ts (testing; treatment; and training of water operators).
The Dungannon wells are designed to the following capacity:
Design Capacity
- 7.6 litres per second
- 656.6 cubic metres per day
Use
The wells’ average usage is: 1.2 litres per second, 104 cubic metres per day
Ontario Drinking Water Standards (ODWS):
Ontario Drinking Water Standards were met in 99.1 per cent of the tests from April 1, 2011 to March 31, 2012. Ontario Drinking Water Standards were not met 100 per cent of the time due to high natural fluoride levels. Arsenic levels are also elevated. In 2012 Well Number One was taken out of service as arsenic levels had exceeded the ODWS standards.
If there is a discrepancy between the information included here and the Approved Amended Assessment Reports, the information in the Assessment Reports usually prevails.
