THE Nigeria Hydrological Services Agency (NiHSA) has raised concern over the contamination of groundwater sources in parts of Kogi and Kebbi states, following assessments that revealed high levels of heavy metals and microbial pollutants.

The Director-General of NiHSA, Mr Umar Mohammed, disclosed this during a media briefing on Thursday in Abuja.

Mohammed said the findings were based on the agency’s groundwater quality assessment conducted across selected locations in Birnin Kebbi, Augie and Argungu Local Government Areas of Kebbi, as well as in Lokoja Local Government Area of Kogi.

He explained that the assessment focused on both the chemical and hydrological characteristics of the sampled water.

According to him, the analysis revealed that two heavy metals; arsenic and lead were found in concentrations far above permissible limits, posing serious health risks to residents who depend on the affected water sources.

He said the World Health Organisation (WHO) standard for arsenic in groundwater is 0.001 mg/L, but samples collected from wells in Kebbi showed concentrations ranging from 0.75 to 4 mg/L.

He also maintained that through forecasts, water-quality updates, drought outlooks, and flood assessment and validation reports, NiHSA ensures that Nigeria does not face disasters blindly.

“Our work provides actionable information that helps governments, communities, and emergency responders act ahead of crises.

He noted as well that Nigeria, a nation where drought is a major challenge in the North and the South battles flooding, “NiHSA’s role is essential: we save lives by helping the country prepare for water-related emergencies.”

He also called on Nigerians to take the agency’s advice seriously and collaborate with it to promote safety, preparedness and enhance resilience nationwide.
