| Descripción: | Costa Rican Guidelines for the Evaluation and Classification of the Surface Waters (IHCA-CR) and the National Sanitation Foundation of the USA (U.S.NSF) water quality indexes, were evaluated during the hydrology year 2007-2008 in Victoria Creek, Costa Rica. A total of 15 sampling sites composed the monitoring network. The water had an incipient contamination (range 4-6 points, IHCA-CR index) and good quality (range 71-90 points, U.S.NSF index) and was moderately hard (range 68-82mgL-1 CaCO3) in 87% de sampling sites and soft (range 33-52mgL-1 CaCO3) in 13% of sampling sites. The dominant type of water in the 2008 dry season was calcium-magnesium sulfate (47% of sampling sites), followed by the calcium sulfate (27% of sampling sites); the remaining sites (26%) had a mixture of hydrogencarbonate and sulfate water. Future monitoring of the water quality and geothermal development effects in the basin should incorporate the following indicators: fecal coliform as bacterial contamination; turbidity as physical quality; dissolved oxygen percentage as aquatic system state; conductivity as dissolved ions content; water temperature as thermal contamination; and chloride as geothermal water tracer. |
