This study was carried out in industrial settings, namely at the asphalt plant, Al-Aseel Company, Al-Jouf Company, and the cement factory. Samples were taken from the cement factory's groundwater wells as well as at the entrance and departure points. There are no sewage tanks nearby, and the groundwater sources are at least three km away from the companies. The secondary containment system used by Al-Aseel Company uses epoxy-coated carbon steel to withstand corrosion from chemicals and extreme salinity, preventing fluid leakage into the soil. To avoid contaminating groundwater, the asphalt plant has a concrete basin with secondary containment. Due to the lack of access to industrial water, AL-Jouf Company depends on a well. Electrical conductivity (EC), total dissolved solids (TDS), pH, turbidity (NUT), chemical oxygen demand (COD), biological oxygen demand (BOD), and coliform bacteria counts were among the chemical, physical, and bacteriological studies that were carried out. Groundwater and river water had pH values between 7.51 and 7.90, which is within an acceptable range of 6.5 to 8.5. whereas the pH of industrial discharge varied between 4.64 and 8.72, suggesting possible environmental effects. Because of the excessive salinity, the asphalt plant's EC was 47,800 µS/cm, which was over permissible limits. Due to industrial waste, the turbidity for Al-Jouf was 1000 NUT, significantly higher than the allowable limit of 20 NUT. While BOD results showed that some chemicals could only oxidize physiologically, COD levels were below 1000 ppm. Furthermore, the amount of fats, oils, and greases (FOG) was higher than allowed. Both the cement and asphalt plants contained bacteria such as Shigella species, Streptococcus species, and Staphylococcus aureus. According to the study's findings, industrial zones have a big influence on the ecosystem and the quality of groundwater.
