Variables
Strengths & Limitations
Strengths
- +Comprehensive analysis using multiple methods (hydrogeochemical and geostatistical).
- +Longitudinal data collection over multiple years.
Limitations
The specific trace metals and their concentrations can vary greatly by location, so findings from one area may not apply directly to another without local testing.
Reliability & validity
The study's reliability is enhanced by collecting samples twice a year over three years and using established hydrogeochemical and geostatistical methods. Validity is supported by comparing findings against established drinking water standards.
Think critically
How might the long-term effects of chronic low-level exposure to these trace metals differ from the immediate health risks identified in this study?
Design Principles
