Abstract
The Sea of Najaf, which is a natural groundwater. 60 samples were studied to locate the amount of 4 heavy metals (Cr, Mn, Co, and Cd) in each sample. With the analysis of three different types of pollution indicators (pollution factor, geographic accumulation index, and enrichment factor), the first heavy metal for which a significant difference can be seen is chromium. The high level of chromium was (101) μg/g, and the low was (50. 9) μg/g. This indicates that the soil was contaminated. Manganese is the second heavy metal with low to moderate contamination. It can be found in soil samples with a maximum concentration of (1022) μg/g and a minimum concentration of (254) μg/g. For cobalt and cadmium levels, the measured amounts do not differ much from the normal limit. This means that the water is not contaminated with them. Contamination indicators are placed in different areas to see what minerals could be in the sediments and where they came from. The results of the study showed that mineral levels were often higher near the edge of the lake than they were further afield. You can find the source of the mineral contamination in the sediments, some of the pollution markers were above the maximum on the beaches but were just below the maximum on the lake. The inverse distance weighted (IDW) in ArcGIS Pro approach is one of the most frequently employed interpolation techniques. It is used to estimate the value of a site that has not yet been assessed by comparing it to the values of nearby sites, the hot spot in ArcGIS Pro This program uses data queries to figure out which parameters for hot spot analysis give the best performance statistics may generate a map with event points or weighted features that show statistically significant hot and cold areas, the results show the distribution of minerals as a map Chromium and manganese are found in nearby farms in high concentrations, A pH test revealed between (7.9) to (10.5), The EC measurement showed between (2.3-4.3) ds/m for water, while the soil ranged between (6.3 – 10.1) ds/m, This indicates that the water and soil are salty. The turbidity ranged between( 13.1 - 8.5) NTU.
