Normally, sand and gravel mining has less impact on pH (Yen and Hashim, 2013; Howladar, 2012).The pH is near neutral may be due to present of limestone outcrop in surrounding area because limestone can buffer pH changes in water and keep it to near neutral. There is no strong correlation between pH and other parameters.
