Nova Scotia's bedrock water wells are classified into high-, medium-, and low-risk zones for uranium contamination based on exceedance rates of the 20 μg/L drinking water guideline. The risk zones were developed by the Government of Nova Scotia using analysis published in an open file report. The dataset was last updated on April 17, 2026.
Use Cases
- Map uranium contamination risk zones for Nova Scotia based on exceedance rates of the drinking water guideline.
- Identify high-risk bedrock units where over 15% of well water samples exceed the uranium guideline.
- Analyze spatial patterns of uranium risk in bedrock aquifers based on the published open file report methodology.
Strengths
- Risk zones are defined by specific exceedance thresholds: high-risk (>15%), medium-risk (5-15%), low-risk (<5%).
- Based on analysis from a published open file report, providing a documented methodology.
- Last updated on April 17, 2026, indicating recent maintenance.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to the Nova Scotia region.
