Improving The Quality of Ground Water in Some Areas of Al-Anbar Governorate by Recharging with Rainwater

Abstract

Artificial groundwater recharged with rainwater is the most popular technique for groundwater quality and quantity. Nevertheless, it is still a challenge for researchers to provide precise quantification of groundwater quality and quantity enhancement by recharging with rainwater due to variations in groundwater quality factors such as topography, hydrogeological phenomenon, availability of rainwater, land use pattern, etc. An attempt is being made here to extract the improvement of groundwater quality by adding the collected rainwater of known quality parameters into the developed aquifer strata in the laboratory with regulated laboratory setup and under similar conditions to the aquifer area of analysis. The results showed a decrease in the pH at all sites, especially A1, where it decreased from 8.2 to 7.3. As for Total Dissolved Solids (TDS), the results showed a decrease in all sites, especially A1, where it decreased from (2860 to 2390) mg\\lit. Also, for CL-, the greatest decline was in A1, falling from (2.400 to 205) mg \\lit. As for the EC values, the site A2 was the lowest, dropping from )5.6 to 4.29 mS/cm). Regarding hardness, the best result was in site B1, where the decrease was from (286 to 220) mg\\lit and finally nitrate experienced the greatest decrease in site B2, where it was from (122 to 78) mg\\lit.
