Lake Victoria in 1990s was invaded by water hyacinth (Eichhornia crassipes) and recently in 2013 with a new water weed resembling Napier. This is attributed to environmental degradation in the watershed, ideal environmental conditions and lack of biological control agents. It is the aim of this study to determine if there is a difference in development and accumulation level of nutrients and heavy metal between water hyacinth and the new water weed and control measures and possible uses of the new water weed. Plant materials and water will be sampled depending on the density and distance from the shore. The new water weed will be taken for classification and the samples will be analyzed for pH, N, P and K. and heavy metal As, Cd, Cr, Pb, Cu and S. A community survey will be conducted involving interviewing occupants. Data will be monitored for a month.
Key words: new water weed, water hyacinth, heavy metals, classification, nutrients, use, control measure, nutrients
