A study was conducted to assess seasonal variation in
physicochemical and microbiological quality of groundwater in
Ruiru, Kiambu County in Kenya. A total of 109 well water
samples, 51 boreholes and 58 shallow wells during 2 different
seasons, viz. dry and wet season were collected during the year
2015 and analyzed for temperature, pH, colour, electrical
conductivity, turbidity, total hardness, calcium, magnesium,
Sulphates nitrate, fluoride, iron, manganese, coliform count and
Escherichia coli Significant difference between seasons was
observed in all parameters studied except, for sodium and
magnesium. The results were compared with WHO guidelines,
2009 and Kenya Bureau of Standards 2006 water guidelines to
ascertain its suitability for domestic use.
