Hydrogeochemical and radium isotope characterization of the Capibaribe River’s water quality in Northeast Brazil

Key Points

• Water quality in the Capibaribe River is significantly impacted by radium isotopes, showing potential contamination levels.
• The analysis reveals radium isotope concentrations exceeding safe limits in some areas, posing health risks to local communities.
• Hydrogeochemical methods were employed to assess the water quality and radium isotope levels in river samples.
• Findings highlight the need for ongoing monitoring and interventions to improve water quality in the region.
