Send your question to Umbra!
Q. Summer is coming, so I wonder if the river near my house (the famous Kamogawa) is safe for my kids to splash in. There is a garbage incinerator upstream, though not directly on the river, and the operators *swear* it does not leak. Is there a water testing kit? What kinds of things would I want to test for? And what kinds of safety limits would I want to look for? It does not have to be drinking-water quality, just safe enough to stick their little feet and hands in.
A. Dearest Gabi,
You’ve just officially made it Water Week here at Ask Umbra. On Monday, we waded into what kind of substances we can safely put in the water; today, let’s address whether or not we can put ourselves in as well.
I hope you’ll forgive me for answering your question broadly. I don’t know how clean the Kamogawa is, nor will my expense account cover phone calls to Japan to check. But I can share some information I hope will be useful to you and anyone else longing for a warm-weather dip in a local waterway.
