“…Other authors 25 have also reported that high-flow conditions due to rainfall may transport increased amounts of sediments and higher concentrations of contaminants absorbed in the suspended solids. Even though chlorinated solvents were not included in the model, it was observed that some concentration peaks can be observed following heavy rain periods.…”

“…For metals an increase in winter consequent on abundant precipitations in the month of November was noted, probably because metals can be adsorbed onto clays and other particulates and carried through karst aquifers as suspended particles during storm flow. 25,30 For manganese and lead this increase was almost immediate, whereas for copper it was slightly delayed. This can be due to differences in transport dynamics or sources.…”

“…Changes in plateau precipitation rates can cause high-flow conditions on the surface 29 and in the aquifer respectively, with the concurrent effect of increasing the amounts of sediments, contaminants and/or nutrients in spring water. 25,30 FA was therefore also used to reveal a generalized response of the karst system to the rainfall.…”

An approach is presented to study the functioning of a karstic massif and assess the adverse effects of the anthropogenic pressure by monitoring some water chemical and physical parameters of its main springs. The approach has been applied to the Sette Comuni Plateau (Veneto Region, Italy) hosting a well developed karstic system, whose aquifer presents high vulnerability and undergoes a relevant anthropogenic pressure. The Oliero springs, amongst the largest karstic springs in Europe, are the main water output of the plateau. Electrical conductivity, pH, dissolved O 2 , hardness, alkalinity, chemical oxygen demand, total suspended solids, ionic species (NH 4 + , NO 3 À , NO 2 À , PO 4 3À , SO 4 2À , Cl À , F À ), elements (Cr III , Cr VI , Mn, Fe, Ni, Cu, Zn, As, Cd, Hg, Pb), and some chlorinated solvents were monitored for one year. This study presents the application of a factor analysis on the water parameters enabling the identification of the dominant chemical and biological processes and pollution sources affecting the karstic system. Results show four factors which are interpreted as karstification, photosynthesis, storm flow pollution and anions. Finally, by associating metals, chemical oxygen demand and total suspended solids with the amount of rainfall in the 48 h before samplings, further detailed information to the fast response of the aquifer to precipitation events was detected and interpreted according to the factor analysis results. The proposed approach, by providing information on the functioning of the aquifer, may help the management of the karstic plateau and is easily adaptable to similar environments.

“…Different types of contaminants are associated with sediments. Conduit sediments can act as reservoirs for heavy metals (Vesper and White 2004) and the highest heavy metal loads in karst spring waters can thus be observed during storm flow (Vesper and White 2003). Dense nonaqueous phase liquids (DNAPLs) also tend to accumulate in cave sediments from which they are remobilised and transported to the spring during floods (Loop and White 2001).…”

These contaminants may be harmful to humans exposed through drinking water obtained from karst aquifers and through recreational activities in caves.…”

Karst watersheds with significant losing streams represent a particularly vulnerable setting for groundwater contamination because of the direct connection to surface water. Because of the existing agricultural land-use and future likelihood of urbanization, two losing-stream karst basins were chosen for intensive monitoring in Boone County, Missouri: Hunters Cave and Devils Icebox. Both caves were formed in Burlington Limestone and have similar recharge areas (33 to 34 km 2 ) and land uses. Year-round monitoring was conducted from April 1999 through March 2002 to characterize the water quality of the main cave streams relative to herbicide, nutrient, and sediment contamination. Water sampling entailed grab samples at regular intervals and runoff-event samples collected using automated sampling equipment. 21 at Hunters Cave. Herbicides or their metabolites were detected in more than 80% of the samples from both cave streams, and herbicide concentrations and areal loss rates were generally similar between the sites. Overall, the greater loads and mass flux of contaminants in the Devils Icebox recharge area compared to Hunters Cave was a result of both greater stream discharge and the occurrence of more cropped fields (94%) on claypan soils with high runoff potential. These claypan soils are known to be especially problematic with respect to surface transport of contaminants. Prevailing land use has significantly degraded the water quality in both recharge areas, but a watershed plan has been developed for the Bonne Femme watershed, which encompasses these two recharge areas. With the baseline data collected in this study, the impact of changing land uses and the implementation of management practices or new ordinances designed to improve water quality can be documented.
