Health effects of Drinking Water Model

This example is model which is built for calculating health effects of drinking water and how water treatment processess affect to the outcome.

Ground water: Pathogenic concentrations

Water resource:

Cambylobacter-concentration estimation (microbe/l):

E.coli O157:H7 -concentration estimation (microbe/l):

Rotavirus-concentration estimation (microbe/l):

Norovirus-concentration estimation (microbe/l):

Cryptosporidium-concentration estimation (microbe/l):

Giardia-concentration estimation (microbe/l):

City default values:

Water purification: Purification processess and chlorinesation

Available purification methods:
Traditional purification
Highly effective purification
Enhanced purification
Slow sand filtration
Limestone filtration
Activated carbon filtration
UV filtration
Ozonisation

Chlorine dose (mg/l):

Water network and consumers

Water consumption (ml):
