“…In spite of the small amount of surface water, the abundance and complex circulation of groundwater is typical for Dinaric karst (Villalba, 1995), which is in accordance with the hydrogeologic characteristics of the dominant rock types. The Adriatic coastal belt and the islands are mainly formed of sediment rocks, i.e., carbonates.…”

The purpose of this study was to monitor and record the specific characteristics and properties of most of the important water resources in Dalmatia located in Southern Croatia for a period of 5 years (1998-2002) according to established standards for drinking water. The paper presents a detailed account of their chemical content, the classification and the concentration of salts. The bacteriological pollution levels are indicated by the total coliform bacterial levels (MPN coli/100 mL). The water characteristics are expressed by coefficients, which represent the ratios between water ingredients. The Ca/Mg eq ratio, SO4/Cl eq ratio and K1, K2 for bicarbonate hardness were calculated. The hygienic characteristics of the water samples were expressed by the total coliform bacteria estimation (MPN coli/100 mL), the permanganate consumption (KMnO4) and biological oxygen demand (BOD5). Karst waters in Dalmatia are moderately hard, the SO4/Cl ratio is 0.38-1.6, non-corrosive (K1 lower than 0.2) and not significantly mineralised (< 500 mg/L minerals). Sulphate waters are generally hard, the SO4/Cl ratio is higher than 1.6, K1 is 0.2-0.65. Marine waters are quite hard or hard, particularly at the river estuaries, the SO4/Cl ratio is lower than 0.38, and K1 is higher than 0.65. The groundwater and springs in Dalmatia are less polluted than surface waters. A majority of these have a geometric average value of MPN coli < 150/100 mL of water observed in 24 of 42 locations studied. The highest bacteriological pollution was found in nine locations where MPN coli > 1000/100 mL and moderate pollution was found in nine locations where MPN coli is between 150 and 1000/100 mL of water. The physical and chemical parameters determined for the most sources in Dalmatia are safe below the international permissible limits.

“…En los últi-mos años, el creciente interés por su adecuada medición se ha puesto de manifiesto en diversos estudios Prat y Munné, 2000;Sánchez et al, 2007;Villalba et al, 1995). Asimismo, la consideración de los aspectos económicos relacionados con el agua y su calidad, también ha conducido a la realización de un gran número de investigaciones (Barberán et al, 2008;Barreiro y Pérez, 2006;Bergstrom et al, 2001;González, 2005;Júdez et al, 2001;Otto y Holtkamp, 1999;Pérez et al, 2010;Ribaudo, 2003;Sevilla et al, 2010;Steinnes, 1992).…”

Análisis de la calidad del agua superficial en la cuenca hidrográfica del Júcar: Periodo 2000-2009 CASINO MARTÍNEZ, A.; VERES FERRER, E. RESUMENEn este trabajo se analiza la calidad del agua superficial en el ámbito de la Confederación Hidrográfica del Júcar, a lo largo del periodo 2000-2009. En primer lugar, se determinan los correspondientes valores del denominado Índice de Calidad General (ICG), en un amplio conjunto de puntos de muestreo y en distintos momentos del tiempo, a partir de los datos observados sobre los parámetros físico-químicos que intervienen en dicho índice. Con los resultados obtenidos se evalúa la calidad del agua superficial, independientemente de su posible uso. Posteriormente, utilizando métodos de análisis de datos de panel, se modeliza el comportamiento del índice general en función de sus parámetros más importantes y otras variables de control. Esta metodología permite tratar el efecto individual específico de cada uno de los puntos de muestreo seleccionados con más flexibilidad que los métodos clásicos de regresión.Palabras clave: calidad del agua, Confederación Hidrográfica del Júcar, ICG, estaciones de control

“…Smith (1990) reported on an index that is based on the minimum operator principle recognizing that it is determined with the lowest subindex rating, which is likely to limit water use. Villalba et al (1995) calculated the statistical indices of Harkins. Petersen (1997) assessed surface water quality by a single pollution index.…”

Water quality in the Dalmatian waters of Southern Croatia was assessed using four different indices: an arithmetic index, arithmetic modified index, geometric modified index, and Solway-modified index. The waters were sampled 12 times during 1 year (from July 1998 to July 1999) at 50 sampling sites in Dalmatia. Nine water quality parameters were evaluated: temperature, mineralization, corrosion coefficient, dissolved oxygen, biochemical oxygen demand, total nitrogen, protein nitrogen, total phosphorus, and total coliform.A comparison of the indices showed that the arithmetic modified index and Solway modified index are relatively similar for high-quality water (i.e., they enable better discrimination between high-and low-quality water). Both indices, however, tend to yield a lower index number for low-quality waters. Water Environ. Res., 75, 388 (2003).
