Drinking Water Quality and Compliance
Town Short Form – A Template for Annual Notice to Consumers
(Note: This short form may be used for communities or waterworks serving a population of less than 5000).

Introduction
The Water Security Agency and the Ministry of Environment requires that at least once each year waterworks owners provide notification to consumers of the quality of water produced and supplied as well as information on the performance of the waterworks in submitting samples as required by a Minister’s Order or Permit to Operate a waterworks. The following is a summary of the Town of Bienfait water quality and sample submission compliance record for the January 1, 2015 to December 31, 2015 time period. This report was completed on January 13, 2016 (must be completed before June 30 each year on a calendar year based reporting frequency). Readers should refer to Water Security Agency’s Municipal Drinking Water Quality Monitoring Guidelines, November 2002, EPB 202 for more information on minimum sample submission requirements and the meaning of type of sample. Permit requirements for a specific waterworks may require more sampling than outlined in the department’s monitoring guidelines. If consumers need more information on the nature and significance of specific water tests, for example, “what is the significance of Selenium in a water supply”, more detailed information is available from: http://www.hc-sc.gc.ca/ewh-semt/pubs/water-eau/index_e.html .

Water Quality Standards

Parameter Limit Residual Range Residual Range Required Submitted Chlorine (%)
Chlorine 0.1 mg/L free OR 0.10 - 2.07 0.00 - 1.31 52 52 100%
Residual 0.5 mg/L total

Water Disinfection - Free Chlorine Residual for Water Entering Distribution System from Waterworks Records-From Water Treatment Plant Records
Test Level # Tests # Tests Not Meeting
Parameter Limit (mg/L) Range Performed Requirements
Free Chlorine Residual at least 0.1 0.00 – 2.58 415 5

A minimum of 0.1 milligrams per litre (mg/L) free chlorine residual is required for water entering the distribution system. Tests are normally performed on a daily basis by the waterworks operator and are to be recorded in operation records. This data includes the number of free chlorine residual tests performed, the overall range of free chlorine residual (highest and lowest recorded values) and the number of tests and percentage of results not meeting the minimum requirement of 0.1 mg/L free chlorine residual.

Chemical – Health Category
All waterworks serving less than 5000 persons are required to submit water samples for SE’s Chemical Health category once every 2 years. The Chemical Health category includes analysis for arsenic, barium, boron, cadmium, chromium, fluoride, lead, nitrate, selenium and uranium.

The last sample for Chemical Health analysis was submitted on August 18, 2014. Sample results indicated that the provincial drinking water quality standards were not exceeded.
