Construction waste such as concrete washout is under severe scrutiny from environment and construction agencies such as EPA, DEP, DEC and DOB largely due to its heavy-metal content, notably chrome. With the rate of construction unlikely to slow down, there will be no let-up in the quantity of concrete washout produced. There needs to be an increased awareness of solutions available to help concrete plants and construction sites meet growing demand, without suffering legal, financial, or environmental consequences associated with waste disposal.This issue is very prominent at construction sites, where there are many common sources of alkaline waters, including: washing chutes and drums used with fresh concrete; cutting or coring concrete structures; hydro-demolition processes; surface water run-off; foundations; placement of fresh concrete beneath groundwater (such as piled foundations),etc...While most are familiar with the dangers of acids, highly alkaline substances such as concrete washout water can be just as corrosive, and if left untreated can cause concrete burns and severe damage to vegetation and the surrounding ecosystem.
