Factsheets on Water Quality Parameters

These factsheets from the Environmental Protection Agency (EPA) can help you to become familiar with common parameters for monitoring water quality. The fact sheets explore aspects of water quality such as temperature, dissolved oxygen, pH, turbidity, nutrients, macroinvertebrates, e. coli, metals, and habitat conditions. Each factsheet examines key questions related to why and how measurements are made for the parameter in question, what can affect the parameter (positively or negatively), and the challenges of using said parameter. These factsheets will be particularly useful for explaining water quality sampling to leaders and outside partners.
