Q. I live on a small lake. I have a dock, and a kayak, and a pedal boat for my niece, and hands that get dirty. I'd like to have the safest possible soap to use on the dock to wash hands and boats and furniture, and so on. Based on my own research, it seems to me that Seventh Generation dish soap may actually meet my needs without harming the lake or the critters therein? Do you concur?
A. Dearest Dennis,
I do not. I don’t mean to sound harsh -- lots of people mistakenly think that biodegradable soaps are OK to use in the water -- but I’ll need to ask you to put down that bottle and back away from the dock.
“Biodegradable” and “nontoxic” sure sound appealing on a soap label, don’t they? Terms like this may lead us to believe that the contents will break down immediately and harmlessly, causing no damage to the complex ecosystem of plants, fish, bugs, and other tiny aquatic creatures in the lake. Unfortunately, this is not true.
