New Jersey Periphyton Bioassessment Development Projects
Trophic Diatom Inference Models and Index Development for New Jersey Wadeable Streams
(2000 - 2005)

The Academy of Natural Sciences (ANS) located in Philadelphia, PA entered into a contract with the New Jersey Department of Environmental Protection (NJ DEP) for the purpose of developing algal indicators of stream and river eutrophication. These indicators would be used to assess relationships between extant water quality criteria (e.g., phosphorus and nitrogen concentrations) and overt signs of eutrophication. They could potentially be applied in a regulatory context as secondary criteria for identifying nutrient impairment. These indicators should be based on an understanding of algal dynamics in New Jersey streams, and be able to distinguish between situations where nutrient concentrations are high due to natural environmental conditions and those that result from anthropogenic influences. Protocols are needed that describe procedures for sample collection and processing, analysis and presentation of data, and interpretation of results.

Below you will find the final and summary reports from the study as well as the protocols.
