Here is a classic example of stupid laws with the intent to "save the environment" that end up doing more harm than good.
Apparently in Spokane, WA one cannot purchase certain dishwasher detergents because it's "bad" for the environment. So all that is available on the shelves are "green" products which aren't very effective. So what are people doing? Driving to Idaho to buy the detergent that actually works; no doubt in their SUV's. So not only is Spokane not keeping phosphates out of the water supply, they're adding carbon emissions from the cars that make the trip to the next state over. Some are running their dishwasher on the "pots and pans" cycle, which uses more water than the normal cycle.
This is just like the stupid "low-flow" toilets now mandated by the Government. You use less gallons per flush, yet have to flush more often just to get the shit to go down, therefore using more water than if you just flushed once with a "regular" toilet. More proof that government interference creates more problems than it solves.
