Whatever you do, if you have a septic system, don't put it down the sink. Maybe once if you follow sundial's advice but don't make a habit of it. If you have municipal sewer then it'll be alright but after letting it settle. I have a heavily wooded area that I'll pour it into, hundreds of feet from the nearest well, including my own. The soil will filter.

You could also do what sundial suggests and filter the liquid after it settles, through a rag or heavy paper towels, let that latex dry and toss it.
