That dissolution of limestone is the solubility of calcite (and hence of limestone) in pure water is very low, but is vastly increased in the presence of carbon dioxide. this gas, dissolved in the water to produce carbonic acid, permits dissociation of calcium carbonate, and dissolution rates and loads are therefore directly related to carbon dioxide content. this accounts for the importance to limestone dissolution of plant growth; soil water contains greatly more carbon dioxide than stream waters. further dissolution occurs due to mixing of saturated waters of different carbon dioxide content (see mischungskorrosion), because of a nonlinear relationship between carbonate saturation and carbon dioxide content. this process is of major significance to continued dissolution within the phreas. cold water can dissolve more carbon dioxide but, with respect to cave development, this climatic factor is overwhelmed by the higher organic activity producing more carbon dioxide in warmer environments. loss of carbon dioxide, by diffusion into open air, causes water to precipitate calcite as speleothems. limestone dissolution may also be achieved by organic acids or by strong acids, particularly sulphuric acid, though such effects are normally far less than that of carbon dioxide. strong acid dissolution is probably involved in the inception of most underground drainage. dissolution by sulphuric acid formed by oxidation of sulfide minerals or gases may be a major cave-forming process in some regions, and was largely responsible for the enlargement of carlsbad caverns and lechuguilla cave, new mexico [9].?

Flow characterization in the Santee Cave system in the Chapel Branch Creek watershed, upper coastal plain of South Carolina, USA., 2013, Edwards A. E. , Amatya D. M. , Williams T. M. , Hitchcock D. R. , James A. L.

Karst watersheds possess both diffuse and conduit flow and varying degrees of connectivity between surface and groundwater over spatial scales that result in complex hydrology and contaminant transport processes. The flow regime and surface-groundwater connection must be properly identified and characterized to improve management in karst watersheds with impaired water bodies, such as the Chapel Branch Creek (CBC), South Carolina watershed, which has a long-term sampling station presently listed on an EPA 303(d) list for phosphorous, pH, and nitrogen. Water from the carbonate limestone aquifer of the Santee Cave system and spring seeps in the CBC watershed were monitored to characterize dominant flow type and surface-groundwater connection by measuring dissolved calcium and magnesium, total suspended solids, volatile suspended solids, alkalinity, pH, specific conductance, and stable isotopes (d18O, d2H). These measurements indicated that the conduit flow to Santee Cave spring was recharged predominantly from diffuse flow, with a slow response of surface water infiltration to the conduit. Qualitative dye traces and stage elevation at Santee Cave spring and the adjacent Lake Marion (equal to the elevation of the flooded portion of CBC) also indicated a relation between fluctuating base level of the CBC reservoir-like embayment and elevation of the Santee Limestone karst aquifer at the spring. Methods described herein to characterize the flow type and surface-groundwater connection in the Santee Cave system can be applied not only to watershed management in the Chapel Branch Creek watershed, but also to the greater region where this carbonate limestone aquifer exists.
