  • Temperature

    This page introduces the temperature module, when to list temperature as a candidate cause, ways to measure temperature, simple and detailed conceptual diagrams for temperature, temperature module references and literature reviews.

  • Ammonia

    This page covers the ammonia module, including when to list ammonia as a candidate cause, ways to measure ammonia, simple and detailed conceptual diagrams for ammonia, and literature reviews and references for the ammonia module.

  • Analytical Examples

    This page includes examples illustrating the use of statistical analysis to support different types of evidence, stream temp, temperature inferred from macroinverterbate, macroinvertebrate responses, zinc concentrations, observed trait characteristics.

  • Manipulation of Exposure at Other Sites

    This page explains how to derive and evaluate evidence using studies from other locations that manipulate exposure.

  • Symptoms

    This page shows how to derive and evaluate evidence using symptoms.

  • Getting Started

    This page provides a guide overview to the step-by-step guide to Stressor Identification, and fundamentals of causal assessment.

  • Step 5. Identify Probable Causes

    This page includes an overview of Step 5, to identify probable cause, then weighing evidence for a candidate cause, comparing evidence across causes, and analyzing the expected output of the causal assessment.

  • Long Creek Conceptual Model Diagram

    Figure 2-2 is an example of a simple conceptual model diagram for increased water temperature as a candidate cause of biological impairment.

  • Figures: Manipulation of Exposure at Other Sites

    These figures illustrate the concept of the type of evidence "Manipulation of Exposure at Other Sites"

  • The Case of DDT: Revisiting the Impairment

    This page is an example or case study showing how the identification of DDT and it's subsequent ban had a positive impact on the reproduction of birds. This is an excellent example of causal analysis with a positive outcome.

  • Iteration Options

    This page provides additional information on the iterative options to consider when you are trying to identify the cause of an impairment. This is supporting step 5 of a causal assessment.
