    The concentrations of heavy metals were determined from wastewater samples collected from the Gusii wastewater treatment plant, from May to July, 2021. Heavy metal analysis was done using a flame atomic absorption spectrophotometer, model AA 7000 Shimadzu, Japan. The results showed that the concentrations of Zinc and Cadmium were below the detection limit for all the sampling sites. The concentrations of Lead and Copper (Mean ± SE) ranged between 0.34 ± 0.06 mg/L and 0.86 ± 0.08 mg/L and 0.25 ± 0.05 and 0.34 ± 0.01 mg/L respectively. The month of July exhibited a higher mean Cu concentration of 0.35 ± 0.004 mg/L compared to the mean Cu concentration (0.2 ± 0.02 mg/L) of May. Likewise, the mean lead concentration of May (0.60 ± 0.04 mg/L) was higher than the mean (0.53 ± 0.05 mg/L.) of July. The independent sample t-test showed that mean Cu concentration difference was significant between the sampling months (t (34) = 21.58; p < 0.05) while for Pb it was not significant between the sampling months (t (30) = 1.241; p = 0.274). The percentage removals of Copper and Lead were generally low at 12.61 % and 6.27 %, respectively. The continued discharge of effluent into River Riana may lead to accumulation of heavy metals in the environment, which in turn poses health risks to the general public. Therefore, the study recommends that Gusii Water and Sanitation Company continue monitoring and assessing the levels of heavy metals in the treatment plant for its sustainability.

    Effect of pond type on physicochemical parameters , phytoplankton diversity and primary production in , Kisii , Kenya
    (Semantic Scholar, 2018-10-23) George, Akunga; Albert, Getabu; James, N.
    The study was conducted to establish the effect of pond type on physicochemical parameters, phytoplankton diversity and primary production in three different types of fish ponds: liner, earthen and concrete at Kegati Kisii, Kenya. The study was conducted from the month of June 2015 to the month of November 2015. Phytoplankton diversity index was calculated by Shannon Wiener index. Statistical significance was set at p < 0.05. There was a significant difference in temperature, dissolved oxygen, conductivity, pH and Secchi depth in the three ponds (ANOVA; p<0.05). There was no significant difference in nutrients measured in the three types of ponds (ANOVA; P˃0.05). In liner ponds Coelomoron mierostoldes species was dominant while Anabaena flos-aquae were dominant in earthen pond while Microcystis aeruginosa was dominant in concrete pond. Liner pond had higher Shannon Wiener index 3.418, earthen pond 3.0439 and concrete pond 1.6414.
