Accreditation of water laboratories is imperative in ensuring efficiency in monitoring the Nigerian Standard for Drinking Water Quality, which will soon be implemented.

An official of the Standards Organization of Nigeria (SON), Mr Louis Njoku, said this on Wednesday in Abuja.

Njoku, the Head of the Laboratory Department of the agency, said that none of the six existing water laboratories was accredited.

The six national water quality testing laboratories are located Enugu, Ondo, Lagos, Niger  Kano and Gombe states.

“ None of the water labs is accredited so far; but the Ministry of Water Resources is putting all its quality manual and technical procedures in place to ensure that accreditation is done.’’

According to him, SON will use the International Organization for Standardization (ISO)’s standard on laboratory accreditation as the guideline for the certification of the laboratories.

Njoku said the accreditation was part of the organization’s collaboration with the Ministry of Water Resources, to ensure that the laboratories were up to international standard.

He added that the SON would monitor drinking water standard and control public water sources like taps, community water treatment plants and boreholes.

Commenting on how boreholes would be monitored, he said the best position to site boreholes and its depth were all enshrined in the standard.

“Enshrined in the standard is how you can approve where a borehole can be sited whether upstream or downstream and so on.

“Even the material that should be used in the construction of boreholes is all enshrined in this standard and who is supposed to approve it.

“So, water from the borehole would be at certain depths following instructions and procedures, putting samples and carrying out analysis you will be able to determine the quality.’’

The head of department noted that lack of commitment on part of relevant agencies was a major challenge in the implementation of the standard for drinking water quality.
