A Simple Stream Monitoring Technique based on Measurements of Semiconservative Properties Of Water

摘要

Correlative relationships exist among conduc- tivity, alkalinity, and hardness in streams due to natural geological and climatological controls, but the relationships among these three water-quality factors can be altered strongly by inputs of ion-rich wastewaters. The degree of alteration can be monitored conveniently by use of a simple chemical perturbation index, computed by subtracting the sum of rank pairwise correlations among the conductivity, alkalinity, and harndess (for observations on each of these variables, measured through time) form 3.0.
