What are my rights as a tenant when renting?

So the situation remains... My husband and I have rented now for a year. Lease will be up in April. However, there have been many health related issues concerning problems with this house that are a top NECESSITY that have been clearly avoided by the landlord to a solution to the continued problems. First off, the sump pump quit, that's not been fixed! its been months! The septic erupted into our back yard and the landlords chose to have someone come out and they instead ran a hose out to our back yard and now all sewage is causing a lake... a bacterial infested lake in our yard! We have serious mold issues now, and had them prior to moving in. My ex husband who is a mold specialist who works for a restoration company found the mold and that's also has been brought to their attention Months ago! Still nothing has been fixed or done about it. The jacuzzi pump isn't working either which is only a minor problem but that was also repeatedly brought to their attention and has still not been fixed. We are paying extra for the jacuzzi as well.. and for what???? Yesterday coming home we find 5 to 6 in of standing water in our carpeted basement filled with our stuff and our stuff is now ruined! The landlord sent someone out and once again nothing was fixed. They did pump out the water and septic but nothing else has been done.... We do NOT have renters insurance as of today's date but we will NEVER hesitate again to carry it... WHAT ARE MY LEGAL RIGHTS FOR MY CHILDREN S SAKE as far as health related concerns and issues????? PLEASE HELP!!!!
