Discussion

Cross-sectional analysis shows sodium and iron exceed WHO standards in Bayelsa's groundwater, suggesting public health risks.

Most physico-chemical parameters were within WHO standards for groundwater quality, confirming its general acceptability.
However, sodium levels exceeded the WHO limit in 78% of samples, with a mean of 235 mg/L, pointing to potential health risks.
Iron content surpassed permissible levels in 84% of samples, averaging 1.8 mg/L, raising concerns for gastrointestinal and organ health.
Targeted policy interventions and community solutions are critical to address contamination and safeguard health in Bayelsa.

Nicholas et al. (2025) studied this question.
