Freshwater Iron Chemistry in Northwest England

Chemical composition data from freshwater samples collected at sites in Northern England. Measurements include pH, dissolved major ions (Na, Mg, K, Ca, Cl, NO3, SO4), dissolved organic carbon (DOC), and dissolved and total concentrations of aluminum and iron.

Use Cases

• Analyze correlations between dissolved organic carbon (DOC) and dissolved Fe(II) concentrations to study organic matter's role in iron mobility.
• Model the speciation of iron (Fe(II) vs. total Fe) as a function of pH and major ion concentrations (Ca, Cl, SO4).
• Investigate regional patterns in aluminum (Al) and iron (Fe) levels across sampled river systems like the Ribble, Lune, and Tees.
• Assess freshwater alkalinity and ion balance using measurements of Na, Mg, K, Ca, Cl, NO3, and SO4.

Strengths

• Includes measurements for both dissolved and total fractions of iron and aluminum, enabling speciation analysis.
• Covers multiple major ions (Na, Mg, K, Ca, Cl, NO3, SO4) and dissolved organic carbon (DOC) for comprehensive water chemistry profiling.
• Data is associated with specific river systems in Northwest England (Leven, Lune, Ribble, Tees, Eden), providing geographic context.

Limitations

• Sample size, temporal coverage, and number of measurement sites are unknown, limiting statistical power and trend analysis.
• Lack of column definitions and sample data prevents immediate assessment of data structure and quality.
