If I was to be running on a budget, I would fill the bath with water. If there is a lot of precipitate or iron present the water will be discolored, if the water smells like hydrogen sulphide then there is possible anaerobic activity occurring, if you have copper in the system & the water has low pH you will start to see a blue color appearing on the white porcelain surfaces after a while. If you have a toilet cistern that holds water look inside & feel the surfaces. If they are greasy you will most likely have a severe bug problem. If there is a build up of solids in the toilet cistern then is possible corrosion products or muck coming from the well. If you are boiling water in a kettle check for scale build up on the elements if this is occurring you may have very high calcium & magnesium present. The most important parameters to test are pH, Ecoli & conductivity initially. If the pH is below 6.00 you will be dissolving metals in your water system & any metals present in the well surfaces will also be dissolving. Check with you local regional council to find out what is present in the local soils at the depth of your well. Hope this helps.
