ABSTRACT: The overall objective of this study was to establish
the effects of steel industrial effluent on Nairobi metropolitan water system
and its impact to the society. The study sought to identify various types of
wastes produced by factories, assess how the waste generated is managed and
disposed, examine the effects of effluent discharge on
Nairobi River and finally propose mitigation measures. The research adopted a
qualitative design and employed a number of methods: direct observations,
document reviews to content analysis of the past studies, which in the end
generated invaluable data. The study revealed that there are four categories of
waste generated: solid waste, liquid waste, footbath chemicals as
well as thermal wastes. It was also found that waste management in place was not effective enough leading to water and soil
pollution. Other causes of pollution were found out to emanate from gasses
contamination to the air and chemicals used during steel processing. The
findings will inform the community of the harmful effects of untreated water
and how it impacts on their health and productivity. It will also help the
stakeholders in the environmental conservation to articulate issues of policy
and influence agenda setting in the national and sub-national levels.
