The water debate continues

Several weeks ago, the Cook Islands water authority, To Tatou Vai, announced it was conducting a six-month trial of Poly-Aluminium Chloride (PACl) as a flocculation agent. Flocculation is a process of settling out particulate matter, for example dirt, from the water. Given that PACl is a chemical that produces a potentially toxic sludge as a byproduct of the flocculation process, this trial needed to be properly assessed for environmental impacts before it was approved.
