Not everything on a water quality report is a health concern — hardness, pH, and turbidity are general water characteristics that mainly affect taste, appearance, and your plumbing, not safety.
Hardness
A measure of dissolved calcium and magnesium — a taste/plumbing consideration, not a health concern.
pH
A measure of how acidic or basic the water is (7 is neutral). Affects taste and plumbing, not a direct health measure.
Turbidity
A measure of water cloudiness from suspended particles.
Manganese
Mainly a taste/staining concern at typical levels; long-term neurological research at high chronic exposure is ongoing.
Iron
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Filtration
These fall mostly outside what carbon and RO systems are designed for — a water softener addresses hardness specifically, and a basic sediment filter addresses turbidity. Neither is typically necessary for health reasons, mainly for taste and protecting plumbing/appliances.
