Oxidation-reduction Potential and Specific Conductance of Ground Water: Their Influence on Natural Forest Distribution
1953
Pierce, R. S.
The mineral content of ground water and its degree of stagnation are closely correlated with specific conductance and oxidation-reduction potential. To eliminate several handicaps involved in sampling and transportation of uncontaminated water samples, a method of direct electrometric analysis of ground water in situ was devised. The assembled portable equipment included a Beckman Model N-2 potentiometer, a modified Wheatstone bridge, and a specially designed well point, accommodating glass and platinum electrodes, calomel half-cell, and specific conductance cell. Electrometric analyses were supplemented by determinations of the content of dissolved oxygen and total hardness. Analyses of ground water in lowland and peat soils of Wisconsin and Ontario have shown definite relationships between the properties of ground water and the natural distribution of forest stands.
