Am I missing some context here? This keyphrase gives me some articles about how UNICEF is helping mitigate the problem of arsenic in drinking water in Bangladesh. This is good, right? Or are they, or other charitable initiatives, somehow responsible for causing it in the first place?

That is how the story goes. Millions of wells were dug via aid that turned out to be contaminated with arsenic then ingested by tens of millions of people. Many of whom suffered over the years thinking they were "cursed".
I don't know how culpable the aid organizations really were, but even if it's just one of those "truthy" things that isn't quite true, it represents what can happen when people are detached from consequences of trying to do good very vividly.
