Abstract
Analyses for concentrations of total ions, Na, K, Ca, Mg, HCO3, Cl, SO4, and dissolved organic carbon, as well as optical density, pH, and specific conductivity, are presented for twenty‐three surface lake waters collected from heathy spruce forest in Halifax County, Nova Scotia, during December 1955. As compared with the average fresh water of the world, these waters are very dilute, and proportionally low in calcium bicarbonate while high in sodium chloride. The three main factors governing chemical composition are shown to be (1) the nature of the geological substratum, (2) the influence of topography as expressed in the accumulation of mineral sediments and peat in and around the lake basins, and (3) proximity to the sea.
