Physico-chemical characteristics and Heavy metal levels in Drinking Water sources in Sokoto metropolis in North-western Nigeria

Abstract Background: One of the factors impeding access to safe water is water pollution. Of particular concern is heavy metal contamination of water bodies. This study was aimed at determining the levels of heavy metals in drinking water sources of Chingola District of Zambia. Methods: A cross sectional study was employed. A total of 60 water samples were collected. Thirsty (30) samples were collected in the dry season in the month of October 2016 and another 30 in the wet season in the months of February and March, 2017. For each season 10 water samples were collected from each of the three water sources. i.e. Tap water, Urban ground water sources and Rural ground water sources. Heavy metal analysis was done using Atomic Absorption Spectrophotometer (AAS).Results: This study revealed that the concentrations of Iron, Manganese, Lead, Nickel and Arsenic were beyond maximum permissible levels in various water sources. Combined averages for both dry and wet seasons were as follows: Iron: 2.3, Copper: 0.63, Cobalt: 0.02, Manganese: 0.36, Lead: 0.04, Zinc:3.2, Nickel: 0.03, Arsenic: 0.05. Chromium and Cadmium were below detection limit in all water samples. The median concentrations of iron, arsenic, copper, manganese in drinking water from the Tap, rural and urban ground water sources were different, and this difference was statistically significant (p<0.05). The median concentrations of arsenic, nickel, manganese and cobalt were different between dry and wet season, and this difference was statistically significant (p<0.05).Conclusions: Sources of heavy metals in water seems to be both natural and from human activities. The concentration of heavy metals in different water sources in this study was found to be above the recommended levels. This calls for improvement in water monitoring to protect the health of the public. Therefore, there is need for continuous monitoring of heavy metals in drinking water sources by regulatory authorities.

Standard Limit

Advance statistical technique as heavy metal pollution index (HPI) was used for assessment of suitability of 17 ground water sources of district Haridwar for drinking purpose. Water samples were analyzed for Cu, Mn, Pb, Zn, Cr and Fe as water quality parameters using atomic absorption spectroscopy (AAS) as per BIS and APHA standards. Results showed that the concentration of all the analyzed heavy metals were found in all the selected ground drinking water sources below their standard limit during the study, except one i.e. only lead was found (0.011 mg/L) more than its standard limit (0.01 mg/L) at H13 during PRM 2014. Suitability of studied drinking water sources have also been evaluated on the rating scale along with determination of seasonal and spatial variations. Results may attribute that HPI of the water sources were generally below its critical limit and studied water sources were safe for human consumption with respect to analyzed heavy metals. The results of the present research work provide significant information for water resources management, which helps to better meet the future challenges.

Heavy Metal Elements

AbstractThe main emphasis of this study was to assess the status of drinking water quality from four different water sources available in and around an institutional campus of Lumami, Nagaland University, with special reference to the detection of trace heavy metal elements. The results of the physico-chemical parameters of the water show that values of DO, BOD5 and free CO2 at S3 are beyond the permissible limit set by WHO and BIS. The values of DO in all the three stations (S1, S2 and S4) are near the maximum permissible limit of drinking water, indicating the deterioration of water quality, whereas the rests of the parameters are below the permissible limit of WHO and BIS. The detection of Hg in all stations along with alarmingly high concentrations of Fe and others such as Cu, Zn, Mn and Se is perceived as a matter of concern. On the other hand, As and Pb were not detected in any station. The detection of Hg and Fe in all the four types of water sources is an indication of contaminant hazards and needs drinking water treatment practices in these areas which in turn have implications on human health.
