Sažetak
The paper present determining the extent of surface water and groundwater contamination by fly ash from road construction. Groundwater and surface water are fundamentally interconnected. It is often difficult to separate the two because they feed each other. This is why one can contaminate the other. Water is an ideal solvent, some products placed on or in the soil will eventually end up in the groundwater. The extent to which human activities threaten groundwater quality depends on the types and amounts of materials use how they are used, and the risk of spills or accidents. Fly ash is a by-product of the combustion of pulverized coal in power station. Fly ash is an amorphous glassy material consisting of silica, aluminum, iron and calcium oxides plus other minor constituents. Fly ash has a long history of usage. It has been used in a variety of applications including as an addition to cement and concrete, for grouting mines and caverns, as a fill material for embankments, as a road construction binder, etc. It is waste material with changeling chemical and mineralogical characteristic. Because of that, it necessary observation its impact on environment and possible consequences at around soil, surface water and groundwater. It needs continue measurement contaminate concentration with stochastic models of transport contamination or measurement in site. Control concentration specific pollutant or group of pollutants in water, air or soil must be in function for protecting human health and environment. Good water management is the key to protecting water quality. Sustainable development requires protect unreturned resources natural aggregates ; it means made the best and economic uses all existing resource.
