The bigger picture
A thoughtful starting point.
White deposits, rusty stains, a sulfur-like smell: water problems often begin with something you can see or notice. That observation is worth recording. It is not a complete diagnosis, and it cannot tell you whether your water is safe.
Start with a useful record
Note whether the issue affects hot water, cold water, or both; whether it appears at one tap or throughout the home; and whether anything changed recently. Include your water source and existing treatment. These details help a laboratory or qualified professional choose the right investigation.
