CI: Contamination Index

In AQuality: Water and Measurements Quality

Contamination Index

Description

Calculate an index that allows to estimate the possibility of microbiological contamination of a water sample after being obtaines.

Usage

CI(sample,data)

Arguments

sample	Code of the sample whose quality you want to know.
data	Data.frame containing code of the database samples,and de concentration of the following chemical components: phosphate, nitrate, nitrite, tkn, ammonium, chemical demand of oxygen (dqo), biological demand of oxygen (dbo) and organic matter.

Details

The CI() function performs the calculation of a score whose value allows to estimate the possibility of microbiological contamination of a water sample after being obtained.

Value

The CI() function returns a number (score). If score>=0 and score<= 2, the sample is not contaminable. If score>2 and score<= 4, the sample is hardly contaminable. If score>4 and score <= 6), the sample is possibly contaminable. If score>6 and score<= 8, the sample is easily contaminable.
