Seepage basins

Sedimentation basins can be used to collect and store surface water flow and to settle suspended solid particles. Seepage basins and ditches can be used to discharge uncontaminated or treated water downgradient of the site. It is important to separate clean surface runoff from contaminated water and store and treat them separately. Table 16.4 summarizes the surface water control methods.

In nearly all oil-producing basins, numerous seeps exist. Early usage of petroleum goes back to biblical times in the Middle East. The fact that seeps are often related to faults and fractures was noted, and it was even observed that seepages along the Dead Sea were activated during earthquakes. 

A seepage control system was installed which consisted of pumping water from wells into the tailings basin to control the further migration of the groundwater plume. The planned reclamation is to add a low-permeability cover on the tailings ponds to control... 

Another possibility is that extensive asphalt seepages occurred in the southern basin of the Dead Sea which many people assume to be the location of the Vale of Siddim (Frumkin and Elitzur, 2002). This basin was very shallow (only a few meters deep) in the 1960s and since then has dried out completely when the lake level dropped to - 405 m, and was completely disconnected from the deep, northern basin (today about 320 m in depth). The southern basin is used now as an evaporation pond for the production of camaUite and the brines are pumped into it through a canal from the northern basin. However, the assumption that the asphalt pits occurred in this area is highly speculative since no asphalt seepages were observed recently in the exposed areas of the southern basin.
