The lady was taking a survey about drinking water - asked some very generic questions.

It's a sales call disguised as a survey. They want to "sell" you water conditioning crap that's so overpriced it's robbery.

Never answer any questions, if you do you'll be identified as a good mark for future scams and you'll get deluged with more junk calls.

We have recieved many calls, so far all have been hang-ups.  very annoying!

Called my cell and asked for my husband. When she said who she was and what she wanted (water survey) I told her I wasn't interested and do not call me again and remove my number. If she calls again I will report it. I am on the State and National do not call list.

Just missed a phone call from this number, no message left. From looking at the previous comments, something did ring a bell. I think this call is mostly likely related to a recent visit to Home Depot, like last week. An associate there approached me and asked if I would like to complete a survey involving water. I did give her my phone number at the time. So I am thinking that this phone call was in relation to this survey.
