Drinking Water Treatment Efficiency Data from Czech Republic Using Passive Sampling

Czech Republic drinking water treatment plants were assessed for residual biological activity using passive samplers and cell-based bioassays. The dataset, authored by Martin Ezechiáš and last updated in April 2026, contains results from six full-scale plants, evaluating raw and treated water. It highlights the presence and removal efficiency of AhR-active and estrogenic substances.

Use Cases

• Evaluating the removal efficiency of AhR-active substances in drinking water treatment based on CYP1A gene expression data.
• Assessing the effectiveness of treatment processes for removing estrogenic activity based on receptor-mediated yeast bioassay results.
• Comparing biological responses across different water treatment plants based on transcriptional data from the RTL-W1 rainbow trout cell line.
• Applying effect-directed analysis to identify treatment-resistant bioactivities based on combined passive sampling and bioassay methodology.

Strengths

• Data originates from six full-scale drinking water treatment plants, providing a realistic operational context.
• Methodology combines passive sampling (POCIS) with multiple in vitro bioassays, allowing for integrative mixture assessment.
• Results include specific biomarker responses (e.g., CYP1A induction) and activity levels (estrogenic, progestogenic) for both raw and treated water.

Limitations

• The dataset is small (286.0 KB), indicating limited scope and likely a summary of results rather than raw experimental data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
