Abstract: Investigations were carried out to study the state of the soil in the territory of the Shetpe South chalk deposit and in the area of the Caspian Cement plant in October 2018. 20 soil samples were taken. Samples were taken from a depth of 0–20 cm. The presence of heavy metals in the soil was determined by atomic absorption spectrometry using AAC MGA-915M (Lumex, Russia), their content was compared with background values and with existing maximum allowable concentrations. The total soil pollution indicator or ZC , using the background, was used to study the state of the soil. The indicators of the soil pollution index were calculated to improve the diagnostic performance of the study area. The calculation of the total soil pollution indicator showed that the value of ZC for all sites was from 3,58 to 5,26 units. The soils are characterized as non-hazardous (ZC < 16), and the assessment of the condition of the soil is biased due to taking into account only heavy metals with KC < 1. The soil pollution index calculations showed that the majority of soil samples at sites PP-1, PP-2 and PP-3 have indicators of soil pollution index > 1, which characterizes the soil as "polluted". At site PP-4 (control) the soil pollution index is 0,74, the soils are "clean". Statistical processing in the environment Statistica 10 showed that the Kruskal — Wallis criterion is statistically significant only for Ni and As (p < 0,05) for soil samples at site PP-2 (at the site of transportation of chalk and dumps). Maps were performed using satellite imagery and using of Google Maps, Mapinfo Professionalv. 12.
