A pollution monitoring study has been conducted to assess the extent of heavy metal/metalloid contamination in subsurface water in the neighbourhood of municipal solid waste (MSW) disposal site in Kolkata metropolitan city, India. On the basis of observed experimental data, the associated carcinogenic and non carcinogenic risks were quantitatively estimated. Water samples (n = 36) were collected and analysed for its toxic metal content by dynamic reaction cell inductively coupled plasma mass spectrometry (DRC-ICP-MS). The average concentration of metal μgL−1 in subsurface water is found as Cr-74.14, Mn-75.78, Pb-19.96, Fe-615.60, Ni-26.71, Co-5.13, Cu-16.33, Zn-750.50, As-42.03, Cd-3.80. The carcinogenic risk is articulated as the likelihood of cancer manifestation through exposure to site related pollutants. Among tested chemicals, arsenic is established to induce cancer in residents of study area. Cancer risk owing to ingestion and dermal exposure is 8.12E04 and 4.32E06 respectively. The total value of incremental lifetime cancer risk (ILCR) for resident is found as 8.16E04. The cumulative hazard index for non carcinogenic risk (Σ HI = dermal and ingestion) for child (1.03E+01) and adult (6.21E+00) reveals that toxic risk is beyond tolerable limit (HQ > 1.00). Alarming values of such hazardous inorganic compounds addresses that there is a risk factor in all kinds of environmental receptors and concerning stake holders. The risk assessment data provides a rational tool for decision makers in corporation level to take up risk management strategies at the polluted site.
