The Göksu
Delta of Turkey is an alluvial delta with intense agricultural activity and has
great ecological and economic significance. Water samples were collected
monthly from 24 wells in the study area, and 13 water quality parameters were
examined. The objective of the study was also to determination the water
quality in wells of the Göksu Delta and assess levels of salinisation in the
region. Piper diagrams and the Geographic Information Systems (GIS) was used to
generate ionic ratios to evaluate water quality in the study area in an
efficient  manner. Overall, the
groundwater examined has medium levels of salinity and low sodium content.  The ncrease in groundwater salinity and
amounts of Na⁺ and Cl^- are indicators of saltwater
intrusion. Rock dissolution and ion exchange were also found to play an active
role in the region. All of these factors affect the sustainability of the
freshwater aquifers and lower their quality for wildlife species.
