Orange or red stains can be associated with iron. Black staining can be associated with manganese. A lab result is needed to identify what is in your water and at what concentration. [25] [24]
Describe the stain before cleaning it
Take a photo and note whether you see the stain at one fixture, on laundry, or throughout the home. Nova Scotia lists orange or red staining as a possible sign of iron and black staining as a possible sign of manganese. The colour is a clue for the lab conversation. [25]
Ask the lab about both iron and manganese
Check whether your lab package includes both. Tell the lab where the sample will be collected and whether it is untreated or taken after existing equipment. Nova Scotia has separate manganese guidelines for health and for effects such as staining. Ask how your result compares with each guideline. [24] [21]
Compare equipment after you see the result
Bring the report, photos and existing equipment details when discussing treatment. Ask which result each proposed treatment step addresses and how it will be checked afterwards. If the report flags a health concern, contact the lab or public health promptly for advice on using your water. [26]
Quick questions
Can clear water still contain manganese?
Yes. Ask a laboratory to measure manganese in a sample from your own well. [24]
Should I choose a filter based on the colour of a stain?
Use the stain to describe the concern. Choose a treatment approach using the laboratory result and the conditions at your home. [26]
