“…pH extremes negatively impact water quality as well as determine coagulants used in water purifcation and treatment [45]. pH values of more than 7 have been reported to change the taste of water and make its treatment more costly [46] while lower pH values (less than 5) are associated with the corrosion of metals due to the higher levels of acidity [47]. Tis damages metallic water distribution infrastructure such as pipes in addition to contamination of the water being distributed.…”

“…Te more organic material there is in the water, the higher the BOD used by the microbes will be [1]. Te fact that BOD was higher in underwater hyacinth environments is proof that the water hyacinth increases the need for oxygen in water [46]. Water with high BOD requires increased use of coagulants to achieve efective clarifcation, thus an important indicator of overall water quality.…”

Water hyacinth (Eichhornia crassipes) degrades and obstructs the integrity of freshwater ecosystems. However, little attention has been paid to monitoring water hyacinth’s spatial extent, its determinants, and its effects on water quality in Lake Victoria, Uganda. The specific objectives of this paper are to (i) assess the spatial extent and distribution of water hyacinth; (ii) examine the determinants of water hyacinth distribution, and (iii) assess its impact on water quality. High-resolution satellite images (2016–2019) were obtained and used to monitor the spatial extent of the water hyacinth, a household survey was conducted to examine the determinants of the water hyacinth’s extent and patterns while water samples were drawn and analysed for physicochemical properties. Results show that the coverage and distribution of water hyacinth varied over space and time. Water hyacinth coverage primarily increased with a decrease in water surface area. The perceived factors that triggered the water hyacinth spread included the morphology of the Bay, effluent discharge, strong winds, speed of water current, water-level changes, ferry navigation, and construction activities at the shore. Water parameters significantly impacted by hyacinth were pH, TP, BOD, COD, DO, turbidity, and transparency. This study recommends the strict development and implementation of integrated weed control measures, catchment management plans, and point and nonpoint pollution source control.
