posted on 2018-02-12, 15:07 authored by M. Senzia, J. Marwa, J. Einsk, Richard Kimwaga, T. Kimaro, D.A. MashauriFor more than three decades, Waste Stabilization Ponds (WSP) effluent has been used by people of
Lemara in Arusha Municipal for irrigation of their farms in order to get better crop yields as source of
their food and income. This paper attempt to examine the produce quality from wastewater irrigated
areas downstream of WSP. The produce from major market and those, which irrigated by water supplied
by approved water authority, were also examined.
Results have indicated that despite the wastewater used for irrigation being treated, produce from the
irrigated area have shown high level of pollution threatening people’s health. Moreover, there is
significant pollution of vegetables taking place in the market probably due to poor hygiene practices.
Contrary to research expectation, vegetables irrigated by water supply have also indicated faecal
contamination although the water itself is bacteriologically safe.
