Irrigation and soil samples were collected and analysed in the laboratory for contamination parameters. One hundred (100) rice farmers were randomly selected and interviewed using a questionnaire. The results showed that majority of farmers used pesticides for rice cultivation. There was strong correlation between farmers’ knowledge on appropriate time of chemical applications, disposal of empty chemicals, farmers’ knowledge on agrochemicals contamination of soil and irrigation water. However, the soil pH and conductivity were within the WHO-EPA acceptable levels.
