How do I report or ask about drinking water problems?

My water has been turning more and more yellow the last few days, leaving a bit of a brown stain (there's no Mn, maybe Fe but hasn't been before). I think I'm under a rural water system--but I haven't heard anything from them about it... Also, if there' s a hole in the line or something who has to pay to fix it?

i left some in a glass for a while and tiny black particles suspended in it began to collect in the bottom but also went to the sides, so I'm figuring some kind of metal w/the charge. It stains my clothes brown.

I would def. find out about that. And smell the water too. Sometimes if a certain facet hasnt been used in a few days that could be the reason. If not def. find out because that doesnt sound right.
