Impact According to the assessment of surface water quality in both areas in Ho Chi Minh city and Dong Nai provinces to base on analysis of samples collected in 2006 that indicated the following characteristics: • Brackish water sampling stations in the Ho Chi Minh city and Dong Nai in the construction project is influenced by the tide • Lower dissolved oxygen standards for the water resources of Government of Vietnam; • No concern about heavy metals, all samples were taken from stations lower than the standard limit for water; • Consideration is that major turbidity and suspended solid concentrations are higher during the dry season, the value exceeded the permitted standard; • Oil pollution index is determined exceed the permitted standards in some locations Technical
