Algal Indicators in Streams

COURSE NO: H03-007
COURSE PROVIDER: Gilbert Gedeon, P.E.
Algal Indicators in Streams
Course Highlights

This online engineering PDH course summarizes the application of algae as indicators of nutrient pollution in water quality management. It describes the use of algal indicators to develop water quality diagnostics for nutrient pollution in the United States (U.S.) and then reviews scientific developments in the use and application of algal indicators across the world.


Algae are ubiquitous and essential components of all stream ecosystems. They are the primary energetic source for many stream food webs, fixing carbon from the atmosphere through photosynthesis, which is then transmitted through the web via consumer pathways.


Algae have a long history of use and possess many of the features valued in ecological indicators. They were part of the early saprobien indicator system development in Germany and were one of the first assemblages developed for use in biological assessment in the United States.


This 3 PDH online course is intended for chemical and environmental engineers and water quality professionals who are seeking to utilize algae to detect the presence of nutrient pollution and to estimate the risks of nutrient pollution in adversely affecting the condition of stream ecosystems.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Gaining general background information on algae
  • Familiarizing with the current algal sampling programs in the United States
  • Learning about the research on algal assessment and indicator using in streams
  • Identifying the quantitative and qualitative algal application methods
