    Summary

    Magnesium oxide and bone meal effectively remove excess fluoride from water, making it safe for consumption. These inexpensive, readily available agents offer simple defluoridation solutions for rural and suburban areas in Kenya.

    Area of Science:

    • Environmental Science
    • Water Chemistry
    • Public Health

    Background:

    • High fluoride levels in drinking water pose health risks.
    • Kenyan water sources often exhibit elevated fluoride concentrations.
    • Effective and affordable defluoridation methods are needed, especially in rural areas.

    Purpose of the Study:

    • To evaluate magnesium oxide and bone meal as defluoridating agents for simulated Kenyan water.
    • To assess the efficacy and palatability of treated water.
    • To determine the suitability of these agents for simple, low-cost water treatment.

    Main Methods:

    • Preparation of artificial water samples simulating Kenyan water with fluoride levels from 1 to 9.3 ppm.
    • Treatment of water samples using magnesium oxide and bone meal as chemical defluoridating agents.
    • Filtration and sensory evaluation (clarity, palatability) of the treated water.

    Main Results:

    • Both magnesium oxide and bone meal significantly reduced fluoride levels to non-toxic concentrations.
    • Bone meal produced clear and palatable water filtrate.
    • Magnesium oxide filtrate was slightly slimy and cloudy but remained palatable.
    • Both agents are inexpensive and readily available in Kenya.

    Conclusions:

    • Magnesium oxide and bone meal are viable, cost-effective agents for defluoridation.
    • These methods can be implemented in simple defluoridation procedures for borehole water in rural and suburban settings.
    • The use of these agents can help mitigate health risks associated with excessive fluoride intake from drinking water.
