| Abstract | Sufficient groundwater or suitable quality exists throughout the Lachine-Saint-Jean area to supply the domestic agricultural and industrial needs of the present population. There is approximately 5
inches of groundwater recharge each year, giving rise to a basin-wide safe yield of 140 gallons per minute per square mile. Salt, hydrogen sulphide, and excessive iron occur in the water in localized areas, but for the most part water quality is
good. Hardness, total dissolved solids, and the nature of the major chemical constituents can be correlated with the source aquifer. Alluvial, glacio-fluvial and buried valley deposits constitute excellent sand and gravel aquifers, which are too
often over looked in the location of high-capacity wells. The bedrock can be divided into three aquifers, which in order of decreasing transmissibility are: (a) Sandstone, (b) Carbonate, and (c) Shale aquifer. The groundwater occurs under artesian
head and is probably part of an unconfined artesian system. Groundwater flow is toward and into the St. Lawrence River and its tributaries. |
