Tenant rights, Arsenic Poisoning, Landlord to provide safe water?

[John Redman]

Hi All, I could really use some advice. I moved to Phoenix area from the midwest and renting a SFH while building a new primary residence. I am married with kids and recently learned, after my 6 month old daughter became very sick that she had arsenic poisoning. I had the well tested and the arsenic level is at 3.3 and the US EPA considers water unsafe to drink over .010. I have incurred medical costs and the costs appear to be rising as I get my family members tested and we start treatment. Is the landlord responsible for providing safe drinking water? Should I be seeking legal counsel? I am not looking to screw the landlord but want them to take this issue seriously and I am worried about the longterm effects this will have on my family. Also, I have medical expenses and not sure what the total will be. Any advice on next steps is greatly appreciated as I just received the well tests back yesterday.
