Assessing drinking water quality and health risks of contaminants in the coastal areas of Cambodia

Abstract The present study aimed to assess the health risks of chemical contaminants residents in coastal areas Cambodia through their drinking water pathways. Water was sampled from tube wells (n= 22), dug 31), ponds 11), canals 12) and lakes 4) across Cambodian areas, measured for concern (As, Cu, Cr, Cd, F−, NO2-, NO3-, Pb, Escherichia coli total coliform) aesthetic quality following United States Environmental Protection Agency (USEPA) standard methods. Analytical results reveal that 9.1% 9.7% contained As > 0.01 mg/L. Appropriately, 22.7% 32.3% Fe 0.3 mg/L while 100% 80.6% Mn 0.1 Health risk assessment found hazard quotient (HQ) 1 children women. Additionally, lifetime cancer (LCR) >1 × 10−4 areas. Therefore, a monitoring programme appropriate treatment remove like arsenic, cadmium fluoride would be required ensure safe supply residents.
