To guarantee the acquisition of representative samples for heavy metal analysis from the composted soil, the cultivated garden area, and the dumpsite, the sampling technique was carried out with great care. The steps in the sampling process are as follows: With the use of a rake, all surface trash and debris within the dumpsite were cleaned out of the sample locations. This made the composted soil underneath easier to reach. To acquire full composted soil samples, the earth was dug down with a shovel to a depth of around 1.33 meters. To avoid interfering with the study, non-degraded plastic items were physically removed during excavation. The magnetic metals in the composted soil samples were extracted using a 1 kg bar magnet. After that, manual selection was used to exclude any metals that were not magnetic. A specified garden area was then filled with sacks containing the gathered composted soil. Both the garden land and the composted soil were tested in tiny containers before to application onto the garden land for a later heavy metal analysis. The sampling containers were carefully cleaned with hot water and soap to reduce contamination, and then they were properly rinsed to get rid of any remaining impurities .
