Almost all of Delta`s cities suffer from high levels of groundwater. The more groundwater table a certain area has, the more various contaminants move. Leakage from sewage pipe lines interacts with groundwater causing different types of soil contamination. Water head travels through soil carrying contamination into further spots. General health is exposed to irreparable danger whenever soil contamination enters the food chain either through crops cultivated in contaminated soil or drinking water. This research presents an application of numerical models in order to investigate the transport process of contamination through a defined area of Delta region. The presented study area has several different uses (residential zones, cultivated area). SEEP/W and CTRAN/W, two Finite Element CAD software products, provide what it takes to track Oxygen-consuming organics (OCOs) contamination through soil by analyzing both Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) as main contaminants. Contamination transport process is investigated throughout various time frames. Several different cases are assumed to observe how contamination can affect the surrounding zones. Both the amount and distribution of contamination values are discussed at selected study nodes during various time frames.
