The use of crustaceans as sentinel organisms to evaluate groundwater ecological quality

- Evaluation of groundwater quality must include biological and ecological indicators.
- Crustaceans are used as sentinels organisms caged inside groundwater.
- Gammarus pulex and Niphargus rhenorhodanensis were chosen.
- An ecophysiological index combined survival rates to states of the body stores.
- The ecophysiological index of sentinels was correlated to groundwater quality.
