Biotic Index BMWP’
(modified Biological Monitoring Working Party)
(Armitage et al., 1983; Modified por Alba-Tercedor & Sánchez-Ortega, 1988)
 Based in aquatic macroinvertebrates families inventory in each sampling point
 A points system ranging from 1 to 10 is asigned to each family on the basis of its sensitivity to water contamination or environmental disturbance
 The index value at each station is obtained by adding the points of each family found.
 A quality class is allocated to each stretch of river, depending of the final points total. This index considers 5 different water quality classes.
 Five different colours are asigned to the different classes for elaborating water quality maps.
Very clean waters > 120
Water not polluted or notably disturbed
Waters with some disturbance
Polluted waters
Seriously polluted waters
Grossly polluted waters < 16
