They determine water quality by collecting and identifying micro-invertebrates. Their data will become part of a state-sponsored stream quality assessment. Further studies include the effects of acid rain on water quality and aquatic life. Girls collect benthic organisms from local streams. Phytoplankton collection requires collection of microscopic organisms which live in the upper portion of water, where light penetrates.
Some chemical analysis is done in the field.
After returning to the lab, benthic organisms are identified for a better determination of water quality. All Rights Reserved.
