Metal In Our Water ? Auto-immunes Gone Whacko ?

Alright, here is the story. So, I have lived in the same house for 14 years. It is in the middle of a farm-country setting in rural WA state, on a creek, beautiful! I am wondering if my well/plumbing has heavy metal poisoning...first my German Shepherd got skin problems, lesions, stunk all of the time...got diagnosed with skin problems and got cortisone shots. Next, my husky/bear dog gets the SAME exact thing...cortisone shots, but has responded well with one each month. 2 of my female cats die of kidney malfunctioning...and another male cat has skin lesions, and gets cortisone shots. NOW, I am getting the symptoms. I got diagnosed with crohn's at age 8, I didn't live here then so that doesn't count. NEXT I had a baby 2 years ago, and experienced all kinds of rashes, eye problems during the whole pregnancy. AFTER a healthy little girl was born, I had to have my right thyroid removed because of a giant lump...cancer...? Who knows, the results weren't conclusive after the 5th expert pathologist. I have been experiencing lesions/itchy scalp for over 2 years. Just got diagnosed today with LICHEN PLANI-PILI-PAROUS or something like that, possibly discoid lupus, we'll know more after the latest ration of blood tests. My husband has problems with his skin and gastro tract, my oldest daughter has the same things starting to manifest. What can be going on you might ask?

The well has tested OK as far as the state of WA is concerned, but I would like to do more tests. I had a hair test done last year-ish and it showed that I did have heavy metal poisoning, but the Doc was an A-S-* so I didn't go back after a few times of him acting GODLIKE:-) When I was in a stained glass class in high school I had solder drip on my leg and it is still lodged in there so I attributed it to that and some crappy fillings...but looking at the evidence, maybe not?!

Luckily we are moving to another place with another well and it will be a new set of plumbing pipes so hooray...hopefully, but I'd like to know so if we are going to sell this lovely little place if it is TOXIC?!?!

So what do you all think? Am I crazy...well possibly...does this sound like metal or what? We do have a lot of iron in our water and it does stain our fixtures.
THANK YOU, THANK YOU, THANK YOU!
