covering a drinking water reservoir with a million polyethylene balls to prevent the sun from reacting with the bromide and chloride to form carcinogens, makes alot of sense.
but if i recall correctly polyethylene is laced with heavy metals to prevent deterioration form UV rays. guess where that goes if being soaked in water for a long time.
as i recall...heavy metals are removed at the water treating facility trough coagulation or other neutralizing methods. carcinogens can also be successfully be removed trough similar processes or some others (like active charcoal or ozonization).
where's the point of putting that many balls and still having the need to remove bromide...i'm sure they made a calculation and i bet the most effective one didn't get the confirmation.
i might be mistaken but this is idea is just counter logical...it's never a good thing to cover trash with trash. well most of the time
