Water Quality Monitoring for the “Big Four Parameters”


Many different parameters can be measured in natural and artificial waters with sensors or via lab analysis. Each parameter effects water quality and the organisms that depend on the water for survival. Different states, monitoring agencies, and companies also place an emphasis on different water quality parameters to be monitored, depending on local conditions and mandates.

For most water quality professionals, in-situ measurement of temperature, dissolved oxygen, electrical conductivity, and pH are considered the standards for basic water quality testing, and are referenced in many official Government guidelines, such as the Clean Water Act.

Stevens Water Monitoring Systems offers several products that make monitoring these parameters a simple task, providing accurate data for decision making. The following article investigates these different parameters, how they affect water quality, and what equipment can be used to measure these parameters effectively.
