2005 First 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 first report for 2005.

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.
