3.1.7 Ground water/soil quality could be impaired by leachates from generated dredged soil

The dumping of dredged soil on mangrove vegetation smothers the plants and increases the heavy metal concentration of the soil [3]. This affects the survival of soil-dwelling organisms by increasing the acidity and alkalinity of the soil. Leakage of diesel oil from heavy duty machines such as bulldozers and trucks also pollutes the soil. Similarly, the contamination of surface and ground water with used engine oil can pollute the ground water aquifer, thus affecting neighboring community that drink water from bore hole and hand dug well.

#### 3.1.8 Impairment of environmental quality

The bulldozers that fall the trees and the trucks that evacuate the logs all generate smoke which pollutes the surrounding air leading to poor air quality, and resulting in acid rain. This leads to the impairment of the health of aquatic and terrestrial organisms around the reclaimed area.

#### 3.1.9 Improper disposal of solid waste

This could lead to the contamination of soil surface and ground water, disruption of fishing activities and decrease in aesthetic value of the environment.
