Results showed that surface water was just polluted by Ni and As, while groundwater was not contaminated by heavy metals.
Emissions of toxic heavy metals can contaminate surface water, groundwater, agricultural soils, and food crops, and they pose health risks to the population via different pathways [2-4].
Besides, the tailing pond can contaminate the groundwater surrounding the tailing pond.
The main objectives of this work are: (1) to explain the content of Pb, Zn, Cu, Cr, Cd, Ni, and As in surface water and groundwater, as well as content variation in all surface water samples along the river, (2) to delineate the heavy metal concentrations in soil and content variation in different soil samples; (3) to determine the content of heavy metals in edible parts of vegetables and rice; and (4) to estimate the health risk to inhabitants produced by heavy metals via various exposure pathways.
In order to investigate the concentration of heavy metals in groundwater in the study area, we collected seven groundwater samples from wells in resident households.،These strategies include: 1) reuse of wastewater, 2) exploitation of groundwater, and 3) finding other water sources.
The maintenance flow discharge should be determined in total consideration of river functions such as navigation; fisheries; tourism; maintenance of clean river water; prevention of salt damage; prevention of river-mouth clogging; protection of river management facilities; maintenance of groundwater level, landscape values, and ecosystems; and the securing of opportunities for human interactions with the river.
The flow discharge necessary to prevent salt damage should be determined such that the effects of saltwater intrusion on river fisheries and ecological systems are minimized, as are the effects of an increase in the salinity of water and groundwater taken from the river for domestic water supply and agriculture.
Maintenance of Groundwater
If the river water is increased, it will definitely contribute to the increase of the recharge of the groundwater.،Results showed that surface water was just polluted by Ni and As, while groundwater was not contaminated by heavy metals.
