Exposure Screening

Rapid screening of contaminants across regions, chemicals, and time

ECMonitor enables rapid screening of emerging contaminants in surface waters by linking site-resolved monitoring records across regions, chemicals, and time. Explore where contaminants occur, how concentrations vary, and which locations may require closer attention.

Human Health Risk Assessment

Monitoring evidence aligned with health-based screening interpretation

ECMonitor provides monitoring evidence that can support screening-level evaluation of potential human exposure. Compare measured concentrations with health-based benchmarks relevant to drinking water and related pathways.

Ecological Risk Assessment

Ecological concern organized across sites and regions worldwide

ECMonitor helps assess potential ecological concern by organizing monitoring evidence for contaminants detected in surface waters worldwide. Explore concentration patterns in relation to ecological benchmarks across sites and regions.

Benchmark Comparison

Measured concentrations compared with guidelines and screening thresholds

ECMonitor connects measured concentrations with available guideline values and toxicity-based thresholds. Identify contaminants, locations, and records that exceed screening or assessment benchmarks.

Priority Setting

Occurrence, exceedance, and spatial coverage combined for prioritization

ECMonitor supports contaminant prioritization by combining occurrence, concentration, exceedance, and spatial coverage information. Use the platform to identify priority chemicals, hotspots, and evidence gaps.

Explore the curated research release: 122 source studies, 4,213 numerical concentration records, 1,722 censored observations, and 386 standardized chemical identities. Includes benchmark audits, chemical classifications, a name crosswalk, and the data dictionary.

This versioned research dataset is separate from the live database. Numerical measurements and censored observations retain their original status and analytical eligibility.
