Great news for Lake of the Woods! New Canadian federal regulations will come into force July 1, 2010 that will effectively ban phosphorus in household dishwashing detergents, laundry detergents, and other cleaning products.
The new rules mirror regulations enacted by Manitoba in 2008 and Minnesota in 2005.
Removing phosphorus from dishwasher detergents alone is estimated to reduce the phosphorus loads to lakes from human sources by about 10%.
The new regulations will impose a phosphorus limit of 0.5% by weight for household cleaners, dish washing detergents (hand and automatic), and laundry detergents.
Phosphorus will still be permitted in commercial and industrial detergents. The ceiling of 0.5% for household products was set to accommodate residues from manufacturers who produce detergents both with and without phosphates on the same production lines.
