Waste Water For Unrestricted Irrigatiion Harmful

dr felixDr Felix Akpabey, an officer in-charge of the Northern Regional Water Research Institute (WRI) of the Council for Scientific and Industrial Research (CSIR), at the weekend said about 52 per cent of urban vegetable growers in the Northern Region depended on polluted water due to scarcity.

“As a matter of fact, waste water is not fit for unrestricted irrigation, which according to international standards, poses risk on agricultural workers, crop handlers and consumers,” he stated.

Dr Akpabey said this at a review seminar organized by CSIR-WRI in Tamale at the weekend to sensitize CSIR-WRI clientele and the public, especially, the scientific community to the activities of the Institute in the Northern Region.

It was also to assess the general ground water potentials and availability of the various types in the Northern Region so as to develop an updated composite of hydro-geological map of the Region.

He noted that the use of plant species for cleaning polluted soils and water known as phytoremediate, has gained increasing attention since the last decade, as an emerging cheaper technology.

Dr Akpabey said contaminant element concentrations of waste water samples from three sources in the Tamale Metropolis were measured before and after treatment.

He said there was a scientific way of testing the efficacy of duckweeds species to phytoremediate waste water for use in urban agriculture, adding that duckweeds were able to reduce about 73.16 per cent of bacteria, and was very effective in reducing between 60 and 100 per cent contamination, making the water less harmful in crop production.

He said the duckweeds also reduce the level of heavy metal concentrations by 100 per cent, which could be used to phytoremediate waste water for urban agriculture.

Mr Gerald Quarcoo, a Research Scientist at CSIR-WRI, explained that water quality in relation to fish production could be described to have physical, chemical and biological properties that affect the survival, growth, reproduction and fitness of fish for human consumption.

He said growth of the aquaculture industry required good water quality to maintain viable aquaculture production in the country.

Mr Michael Kumi, a Research Scientist with the Environmental Chemistry Division of CSIR-WRI, said quality water implications of any proposed aquaculture activity should be addressed, especially, where there was a risk of discharge from farms, or where operations would be conducted in cages, shallow or confined in water bodies.
