Salt is the maximum commonly spread inorganic chemical in all over the world. It is a part of human food, and life without salt is improbable. Salt is widely used for cooking, preserving and for preventing roads from icing up. The study was carried out from March 2010 to September 2010. The salt samples were collected from Araly, Thanuvil, Uppuveli, Chemmani and vallai in the Jaffna peninsula, Sri Lanka. To determine the standard value, salt samples were collected from Puttalam and Palavi salt producing areas. The water, salt and soil sample were collected from Araly, Thanuvil, Uppuveli, Vallai, Chemmani, Kalundaiveli, and Kaarainagar in the Jaffna peninsula Sri Lanka. In this study salt, water, and soil were analyzed for physical (pH, color, taste) and chemical (Cl-, SO42-, Ca2+, Mg2+, Na+, K+, PO43-, Fe3+, total alkalinity and total solids) characteristics. The salt quality in all the salt samples except Thanuvil, are chemically safe for human consumption. Even though there are some visible impurities present in the salt. Chloride content of the Vallai and Chemmani areas were highly deviated from standard levels. In water analysis, magnesium, and calcium contents of both of Araly and Thanuvil, chloride content of the Uppuveli, potassium content of the Araly and sodium content of the Vallai were highly deviated from standard levels. In the soil samples, chloride content of the Uppuveli and Vallai, magnesium content of the Araly and Thanuvil, potassium content of the Kaarainagar were highly deviated from other places. In the correlation analysis between water and soil samples most of the quality parameters such as pH, Cl-, SO42, PO43-, Fe3+, total alkalinity and total solids are closely correlated to each other (70%-81%) and other parameters-, Ca2+, Mg2+, Na+, K+, weakly related to each other (40%-70%).
