Abstract
The quality of groundwater should be improved by keeping safe water sources from contaminants in protective way by doing regular measuring and checkup before it supplied for usage. Private Wells do not receive the same services that wells supplying the public do. Well owners are responsible for protecting their drinking water. This work was carried out in Badra city, Iraq from December 2017 to May 2018, six wells water were investigated to determine the general characteristics of wells as well as studying the effect of environmental factors on the quality of water. The average of six wells were eleven parameters that is out of permissible limits were EC, Sal., Alk., TH, TDS, Na, Ca, Cl, SO4, Fe, Zn (4402-5183 /cm, 2.76-3.9 ppt, 302-366mg/L, 3164-4248 mg/L, 604-675 mg/L, 375-524 mg/L, 635-871 mg/L, 631-1107 mg/L, 2430-4570 g/L, 114-392 g/L). Respectively, microbiological investigations involved the total coliform, total plate count, as well as the detection for the presence of E. coli, Salmonella and Cholera. Results shows that there is a significant relation between the increasing of the TDS and Turbidity, TDS gives an indication for the significant increasing of chemical ions. Wells number 3, 4 and 5 showed gave positive results for E.coli growth which as a source of microbial pollution. Detection for the presence of chemical and microbial contaminate is an important alarm since this water has a direct effect on the human and animal's health. Advance method of rapid detection for the well water quality is highly recommended to avoid any health issue and prevent the outbreak of health risk and ecological contaminants.
Highlights
Groundwater's is the major source of drinking water in both urban and rural areas
Driven wells can be initiated in unconsolidated material with a well whole structure, this is normally consisting of a hardened drive point and a screen of Department of Biology, College of Science, Mustainsiriyah University, Bagdad, Iraq E-mail: khzwaini@yahoo.com perforated pipe,after which a pump is installed to collect the water [3]
The study area is in Badra city, is located east boarding Iran and within Wasit province, 70kms northeast the city of Kut and 190kms southeast of the capital Baghdad
Summary
Groundwater's is the major source of drinking water in both urban and rural areas. Rural and urban areas use groundwater's as a type of freshwater. 90% of freshwater are coming from groundwater's as a source in the earth. Water in a well is a model created in the ground by many methods either digging, or drilling in order to access the groundwater in underground aquifers. Driven wells can be initiated in unconsolidated material with a well whole structure, this is normally consisting of a hardened drive point and a screen of Microorganisms which originate from human activities (urban, industrial, and agricultural) and released into the environment by direct discharge, insufficiently treated wastewater leaking sewage and septic systems can contaminate groundwater [5, 6, 7, 8]
