Water Utility Water Testing

Policy No.: 2017-7
Supersedes: 2001-2
Effective Date: June 19, 2017
Approval By Council Motion No.: 6

Purpose:

As a minimum, the water utility will meet the Guidelines for Monitoring Public Drinking Water Supplies of the Province of Nova Scotia’s Water and Wastewater Facility Regulations.

 

General:

The potential sources of supply for the water utility are, in order of priority:

  1. Three drilled wells in Granville Ferry
  2. A pond reservoir in Granville Ferry
  3. Grand Lake reservoir (First Pond)

 

The drilled wells are the primary source of water supply to the Town of Annapolis Royal, while the pond reservoir in Granville Ferry is the primary back-up supply. The Municipality of Annapolis County has responsibility for initial testing of these sources. Grand Lake is a secondary back-up source in the event both of the above sources are unavailable, or in the case of a major fire emergency.

 

The Superintendent of Public Works is responsible for the implementation of these policies and procedures, unless otherwise indicated.

 

Training and Education

Operators of the Water Utility will receive training in the operation of the system, including Water Treatment Level I. Training is ongoing on a yearly basis.

 

Testing Procedures

The Municipality of the County of Annapolis and the Town of Annapolis Royal carry out the following testing:

 

  1. Once per day at the Water Treatment Plant in Lequille for chlorine residuals and PH levels. This is carried out by Public Works for the Town of Annapolis Royal. Results of these tests are faxed monthly by Town Staff to Nova Scotia Environment.
  2. Coliform Bacteria content or bacteriological samples are carried out once per week by the Municipality of the County of Annapolis at the County of Annapolis Public Works building in Granville Ferry, the County of Annapolis Municipal building in Annapolis Royal, and at the end of the line in Lequille. Based on the average sample readings and discussions with Nova Scotia Environment, required chlorine residual levels at these locations should be approximately:

County of Annapolis Public Works Building: 1.08mg/litre
County of Annapolis Municipal Building: 0.9 mg/litre
At the end of the line in Lequille: 0.6 mg/litre

 

These readings are submitted to the Valley Regional Hospital by the Municipality of County of Annapolis for testing for Coliform Bacteria. A copy of the reports are also submitted to the Town of Annapolis Royal by the Municipality of the County of Annapolis.  If levels are higher than normal, Public Works will contact the Municipality of Annapolis County to inquire if there are any reasons contributing to the variances.

 

Corrective Actions to be Taken When Bacteria are Present:

Valley Regional Lab and/or Nova Scotia Environment will communicate to the Superintendent of Public Works the procedure to follow for resampling, in case of human error.  Nova Scotia Environment, in conjunction with Valley Regional Lab will issue all orders for Public Works to follow.

 

Boil Water Advisories

Where a boil water advisory is required, notification will be immediate, and in order of priority, as follows:

  1. CAO and Superintendent of Public Works
    2. Mayor
    3. Hospital
    4. Nursing Home
    5. Schools
    6. Restaurants and Bed and Breakfasts
    7. General Populace

 

A call list for the first six categories will be prepared and updated regularly. Radio and door to door calling will be made to inform water utility customers of the boil water advisory. The CAO is responsible for preparing the call lists and for ensuring the advisory activities are carried out with dispatch.

Grand Lake Water Usage

In the event Granville Ferry water is interrupted to the Town, Grand Lake water will be used as back-up. A Boil Water Advisory will be issued immediately. The Boil Water Advisory will be continued until testing indicates to the NSDOE, MOH & the Town that it should be lifted.

Under unusual fire circumstances, untreated Grand Lake water may be introduced to the water system by the order of the Fire Chief after consultation with the Mayor. A Boil Water Advisory and recommendations to Water Utility customers not to drink the water will be issued. Once the Grand Lake water has been shut off, the Boil Water Advisory will be continued until testing indicates to the NSDOE, MOH & the Town that it should be lifted.
