Abstract: The heavy metals from the soil and surface water of the mangrove forest of Alibaug, Maharashtra, India were estimated by the Atomic Absorption Spectrophotometer (AAS). The samples were collected from eightteen sites, fifteen from the mangrove area and the rest from Akshi beach along the Arabian Sea. The concentration of heavy metals in the surface water was found in the order of Co & gt; Cd & gt; Cu & gt; Ni & gt; Cr It was found that the concentration of Cd and Co in the water samples exceeded the standard levels that are prescribed by BIS, WHO and US EPA. Enrichment factor values showed moderate enrichment for Cu and Co and high enrichment for Cd due to anthropogenic sources. Contamination factors (CF) gave values indicating moderate contamination by Cu and Co, and very high contamination by Cd. Variation maps show that the study area is ranged between the PLI value of 0.5-1 and 1-1.5 in the surface and depth of the soil, respectively, indicating higher pollution by heavy metals in the deep soil. It was found that there was no pollution due to Fe, Cr, and Ni in the study area while surface water and soil were moderately polluted by Cu and Co and highly polluted by Cd
