Another factoid from my Living Green: 365 Ways to Make a Difference calendar:
"Your toilet is not a wastebasket, and it’s wisest not to use it that way. Disposable diapers and tampon applicators are among the many items that sewage treatment doesn’t treat. All too often, they pass through the system and wind up in waterways and on beaches."
I hate to admit my ignorance here, but I had NO idea. I thought if you were on city water/sewer (vs a well and septic) you were OK! Whatever you put in the toilet went magically away to the water treatment plant and was filtered out, the water treated and back to our water facets it went.
Of course I know better than to toss a disposable diaper in the toilet, but now I'll be more conscientious about, um, other items!
