| Abstract: | Fifty-four surface and twenty drill-hole waters were sampled in the vicinity of the old Eustis mine in the Eastern Townships of Quebec. Some of these waters were tested periodically over a three-month period. The purpose of the investigation was to develop a method for locating sources of anomalous waters using chemical analyses together with geomorphic and geologic evidence. Techniques have been developed which use chemical and hydrologic theory to estimate travel distance and location of the approximate source area of a water. The travel distance can be approximated as a function of hydraulic head, sodium concentration in the water, and an approximate constant which must be derived for the area.Water samples having anomalous concentrations of copper or zinc can be ascribed, in the specific region of this investigation, partly to contamination from mine workings (35%), partly to known mineralization (25%), and partly to unknown causes (40%). |
