2.1. The Environmental Impact of Tunneling Operations Table 1 shows an inventory of all the environmental aspects that can play a role during the realization and exploitation phase of a tunnel. Creating new paths to access the tunnel face, destroy landscape and existing environmental conditions. Construction of road access is an inevitable intervention in the environment that causes significant impacts by removal of trees, earth excavation and embankment. In general, geomorphologic alteration, changes in working surface, ground water level, potential increase of erosion phenomena, destruction natural inhabitants of animals and plants, increase of dust concentration in the atmosphere and decrease in prices of surrounding areas are adverse environmental effects of the access and exit roads. The main sources of noise in the tunnel during construction include: • Noise from blasting for excavation tunnels • Noise from drilling machines, instruments, loading, etc. • Noise from traffic and transportation around the tunnel • Noise from loading and haulage • Noise from fans for tunnel ventilation One of the most significant undesirable impacts on the environment is disposing of excavated materials during the tunnel excavation. Disposal of waste materials in the construction of the tunnel is a type of effects that can create detrimental effects on environment such as water pollution, soil contamination and pollution of natural ecosystems. Tunneling operations can change the direction of groundwater flow and cause environmental impacts on soil chemistry. Water flows in the springs and where the water naturally comes out, may be decreased due to groundwater discharge from drainage of surrounding grounds of the tunnel site. Disposal of waste water remained from tunneling also have undesirable impacts on the environment. Because as regard to the possibility of contamination of these waters and emerging at surface can create irreversible problems for living things.
