Abstract

The integration between the environmental chemistry and remote sensing data can be considered a new approach introduced through this study to investigate and monitor the ambient environment. The research findings relative to chemical and bacteriological analyses show disparities in the elements' concentrations of wastewater (influent, effluent, seepage, and overflow) with a salinity range between 3539 and 9509 mg/l. Groundwater salinity values range from 3680 to 11471 mg/l, NO3 (1.4 to 11.2 mg/l), viable bacteria (16 to 70), COD (70 to 125 mg/l), BOD (15 to 40 mg/l), and TOC (90 to 192 mg/l). These data reveal the penetration of the wastewater till a depth of 125 m. To discuss the impact of wastewater on the carbonate landform, a new chemical approach has been presented. In this approach, the water chemistry was expressed by their hypothetical salts, whereas the rocks were expressed via their main chemical constituent (CaCO3, 95%). The approach provides the possibility of creating all the potential chemical reactions with their equations. The obtained equations indicate possibility of rock dissolution, crumbling and continuous release of CO2 (a greenhouse gas). The results of the study led to recommendations to protect the region's unique landform and work to resist environmental degradation.
