Investigation of Portable Groundwater Quality and Health Risk Assessment of Selected Trace Metals in Flood Affected Areas of District Rajanpur, Pakistan


Sarfraz MD*, Sultana N, Jamil MD and Ashraf R

Groundwater contamination is an important issue due to its toxicological effects on ecosystems and impact on public health. In this view, 120 water samples collected from flood affected areas of district Rajanpur, Pakistan were assessed for physical parameters (colour, odour, pH, turbidity and conductivity), minerals (Alkalinity, Na+, K+, Ca+2, Mg+2, Cl-, SO4 -2 and TDS), micronutrients (F-, As, Fe, Mn, Zn) and microbiological organism (total coliform and faecal coliform) to understand its suitability for human consumption and health risk associated. Analysis data revealed that 75 and 57% water samples were contaminated with total coliform and faecal coliform bacteria respectively. Other than this, a number of water samples were having high level of minerals, micronutrients and other chemical constituents. Health risk assessment due to high concentration of Fe, Mn, As and Zn was carried out by calculating chronic daily intake (CDI) and health risk index (HRI) for both adults and children separately. Calculated CDIs and HRIs were found in the order of Mn>As>Zn>Fe and As>Mn>Zn>Fe respectively. Results showed that HRI>1 for As in 46 and 37% water samples for children and adults respectively, posing serious threats to the healthy life of the local community.
