Most of these people have lived off their water source all their life. To them, "it's fine". They'd like it cleaner - but they'd also like their house smarter, their kids better educated, their bike cheaper to run and their roads to have fewer potholes. That's literally what everyone wants. But without education, they won't realise that the slightly murky water is what caused their child to get sick and die, or that the arsenic poisoning is why they've been low on energy for their whole life and struggle to concentrate in class. Most people - both in developed and developing nations - don't understand the importance of clean water vs all the other things they'd like in their life. Heck, in my travels I've met a lot of people who get water from a stream to drink, and even own a water filter, but can't be bothered to use it because it takes a few minutes for the water to seep through.
