The study is to evaluate the effect of bank protection concrete block products to streams and soils. The effect on three types of bank protection concreteblocks was evaluated.. The first type was manufactured using fly ash, and the second and third type products used fine blast furnace slag powder. Thelaboratory and field Experiments test results showed the pHs of 9 or less. Also, any heavy metals were not detected in the heavy metal leaching tests. Although some iron (Fe) was partially detected, it still met the water quality standards. In addition, heavy metal was detected from all blocks by theUS drinking water evaluation standards method. An on-site water quality and soil contamination tests were performed at the places that the blocks wereimplemented in practice. The test results showed that the application of the bank protection concrete block product did not lead to the water and soilquality degradation. Therefore, it was found that the hardened bank protection concrete block product did not elute harmful substances such as heavymetals that affect water and soil quality degradation.
