Abstract

Introduction: Mukim Salor is one of the agriculture areas in Kelantan. Farmers usually use fertilizers for paddy and vegetables. The use of chemical fertilizers can lead to contamination of nitrate in groundwater by the leaching process. Kota Bharu is one of the cities in Malaysia that use groundwater as the main source of water supply. Daily use of groundwater that is contaminated with nitrate, can lead to health problems such as methemoglobinemia or "blue-baby syndrome" and shortness of breath. There is no data that show the nitrate level and hazard index from the nitrate exposure in groundwater at Mukim Salor. Objectives: To determine levels of nitrate in groundwater and health risk among respondents in Mukim Salor in Kota Bharu, Kelantan. Methodology: This study was conducted among residents at Mukim Salor in the district of Kota Bharu, Kelantan. A total of 50 respondents were chosen based on the inclusive and exclusive criteria. Groundwater samples were taken from each of the respondenfs house. It was then analyzed by using a direct reading spectrophotometer HACH brand DRI 900, while a set questionnaire was used for health risk assessment of the exposure. Results and Discussion: The mean± SD of nitrate level was 1.08 ± 0.64 while the range was from 0.00 to 2.8 mg/L. According to p-value (0.38), it indicated that there was no significant difference of nitrate levels between these 3 villages. Nitrate level in groundwater at Mukim Salor has not exceeded the standard and there was no significant risk of nitrate contamination in ground water whereas the HI is less than I. Conclusion: The groundwater at Mukim Salor was considered safe for drinking and cooking purpose. However. everyone should be concerned about the nitrate level in drinking water because it will give a bad health impact to the consumers. Keywords: Nitrate, groundwater, contamination, health risk assessment, Muk.im Salor
