oprint(RawConcentration)

Rationale

Raw water has been categorized based on its source and cleanliness:

Ground water - clean
- Clean groundwater
Groundwater - surface water contamination
- for ex. shore infiltration
Surface water - low contamination
- Relatively clean surface water
Surface water - medium contamination
- for ex. low waste water contamination
Surface water - high contamination
- for ex. waste water contamination

Data

The concentrations are based on experts' estimates on concentrations of different pathogens in different kinds of raw water sources and contamination situations. ^[1] ^[2] ^[3] ^[4]
