Sustainable and safe use of groundwater requires
periodicalmonitoring of its quality. Because of the presence of
multiple contaminants, spatial variation of overall groundwater
quality is difficult to describe. The present study describes
the overall groundwater quality for irrigation using a multicriteria
quality assessment system and sustainability of water
use by incorporating the aspect of temporal variation of
groundwater quality. The GIS-based multi-criteria system effectively
amalgamated different quality parameters into an
easily understandable format and assessed the spatial variation
of groundwater quality for irrigation in west Delhi, India. The
rate of spatial increment of poor quality groundwater within
the study period was 3.7 km2 per year. It has been observed
that there is deterioration of groundwater quality from southwest
to east, along the general groundwater flow direction,
and improvement of groundwater quality from west to northeast,
due to less urbanization and availability of groundwater
recharge zones with good quality water. Temporal variation of
groundwater quality is high (V>20 %) at northern part, moderate
(V=10–20 %) at middle and southern parts, and less (V
