Abstract

Introduction: Nitrate is the most commonly found contaminant in the world's aquifers. The main concern on concentration of nitrate had increased globally due to application of inorganic fertilizer and manure in agricultural sector. Human activities have interfered in many ways with natural water cycle and affect the society-water relationship. Thus, it increased demand on food in agricultural product, and had raised future risks from high usage fertilizer to boost up the yield. Nitrates used in fertilizers are commonly found in drinking water sources, particularly in agricultural areas where nitrogen fertilizer is used and raise risk factor such as methamoglonbinemia and colon cancer. Private Wells nearby agricultural activities are more at risk of contamination as most of rural area in Kelantan still depends on well water as their main source of water. Therefore, probability of harmful effect can be quantified to assess the health risk in the selected population area. Objectives: To determine the health risk and concentration of nitrate in groundwater at rural area in Telaga Ara Village, Bachok, Kelantan. Methodology: This study was conducted among residents at Telaga Ara Village, Bachok, Kelantan. A total of 56 respondents are chosen based on inclusive and exclusive criteria. Groundwater samples are going to be taken from each of the respondent's houses. Then, it be analysed by using Portable PH/ORP/ISE Meter model H198191 and Probe Model H14 113, while a set of questionnaires was distributed among respondents for health risk assessment of the exposure. Result: The groundwater at Telaga Ara Village, Bachok, and Kelantan was considered safe for drinking and cooking purposes; however, nitrate concentrations in drinking water should be monitored as a precaution to avoid any side effect towards Health. Conclusion: The groundwater level in Telaga Ara village was considered safe for human consumption and usage purposes. There was no significant in health index that can contribute towards non-carcinogenic risk. However, level of nitrate in drinking water should be concerned as it will affect human's quality of life in a long run exposure. Keywords: Nitrate, Well Water, Bachok, Paddy, Groundwater
