Hydrogeological study


Saint-Lazare, Wednesday, August 23, 2017 - Pumping trials are now over. Analyses are in progress.

The readings for the observation wells under study will take place until September 21st, 2017, 30 days after the pumping trials have stopped.

Pumping tests on three (3) wells in the Pinière sector

Infrastructure: ongoing pumping work

SAINT-LAZARE (Quebec), July 20, 2017. -  With a view to supplying the territory with quality water and a sufficient water flow rate, the Town of Saint-Lazare has recently initiated a hydrogeological study aimed at exploring water sources from three (3) wells located in the Pinière sector near Parc nature Les-Forestiers-de-Saint-Lazare. This second phase involves clarifying the results gathered during the first seventy-two (72) hour exploratory phase carried out in 2014.

The study consists mainly of pumping groundwater from the rock aquifer from all three (3) wells continuously for a period of sixty (60) days, specifically from July 15 to September 11 inclusively. Three (3) generators are used to ensure adequate pumping for the duration of the testing period and a truck will be circulating daily in order to power these generators. Pipes will be positioned to re-direct most of the water to sandy areas located nearby so that it can be absorbed into the surrounding soil.      

Once the pumping tests are complete, the quality of the water and the possible rise of the water table level will be verified in previously selected private and public wells. The Town of Saint-Lazare, which is currently supplied with drinking water through wells on different sites located within the perimeter of the territory, wishes to clarify that it is exploring the last possible site capable of meeting the population’s demand for water. This study is therefore necessary before significant funds can be earmarked for the permanent development of these wells.    

The Town of Saint-Lazare, acting as the main contractor for this project, would like to reassure the public that the personnel assigned to the task is doing everything in its power to avoid inconveniencing trail users. At the same time, the town also wishes to advise the public that certain inconveniences are possible for the duration of the testing period. As a result, certain portions of the trails are likely to be temporarily inaccessible to the public. Signs will be posted to inform walkers, hikers and horseback riders which particular sections will be closed as well as the timeframe for these closures, where applicable. Parc nature Les Forestiers-de-Saint-Lazare users are advised to be cautious and respect signage along trails and paths.
