2004 Third Quarter Test Report

Laurentian Valley Water Works manages just over 13 kilometres of water main and branch lines in the Township. Laurentian Valley Water Works received its Certificate #2893 as a Water Distribution System Class 1 in November of 2000. The Drinking Water System Information number for Laurentian Valley Water Works is W260007465. This is the third report for 2004.

Laurentian Valley Township has a water servicing agreement with the City of Pembroke. The water is purchased from the city and distributed in the Stafford Village area, part of Pembroke Street East and part of Pembroke Street West. The City treats and tests the water at the Pembroke Filtration Plant on Riverside Drive and tests the water in their distribution system. The Municipality tests the water in its distribution system.

This report and the Certificates of Analysis are available to the general public at the front counter of the Municipal Office at 460 Witt Road during office hours.

Quality Analysis

Water sampling was conducted by Claus Trost, Water Quality Analyst, Certificate number 12228 and Mark Zadow, Operator, Certificate number 13145. The water samples were sent to Caduceon Laboratories Inc. in Ottawa for analysis. Caduceon is an ODWS Accredited laboratory. The results of the analysis are faxed back to the Municipality. The following chart is a summary of those test results.

Another three samples were taken on August 3, 2004 of which all tested clear.

Complaints

A complaint was received from a resident on Lark Street in regards to dirty water staining their laundry. This was traced back to flushing of the new mains installed in Willow Ridge Subdivision. The normal water flow was reversed in the steel water mains on Willow Drive and Roy Street, causing the rust scale to slough off.

Staffing & Training

Laurentian Valley Waterworks has 1 Water Quality Analyst, 2 operators certified Water Distribution- Class 1 and has started two operators in training. Staff attended a course on Watermain disinfection on August 16, 2004, by Canadian Environmental Training.

Maintenance

The works department replaced a blow off on the west end watermain.

Construction

Three new residential services were connected in the third quarter. The works department supervised the flushing and testing of the new watermains installed in Phase II of the Willow Ridge Subdivision.

Ministry of the Environment

The audit report has not been received from Christine Villeneuve, Provincial Officer of the Drinking Water Management Division. Ms. Villeneuve attended the Office of Laurentian Valley Water Works on June 28, 2004 to audit the Distribution System. The Municipality has engaged Jp2g Consultants to write a letter to Brad Ross explaining the Municipalities exemption of the requirement to submit an engineers report as required in Ontario Regulation 170/03.

Summary

In the third quarter of 2004, the Municipality purchased 15,150,790 gallons of water from the City of Pembroke and distributed it to 535 homes and businesses. Water quality analysis has revealed two incidents of adverse water quality which were deemed to be sampling errors.
