Safe water

Hey everyone! I’m honestly not sure if this is the right forum for this or not but it’s worth a shot in any case. So I live just south of where a train derailment happened in Ohio. Maybe you’ve seen it on the news. Anyhow chemicals are being found in the river I live on but the water department says they are treating it to have them gone or harmless by the time it leaves the treatment plant. Personally I want to buy water but I’m not sure if it matters what I buy. I have reptisafe water treatment already but wanted to know if it mattered if I got spring water or distilled or whatever. I greatly appreciate the help. My tortoises, fish, skink, and cat would appreciate the help as well.
