Tracing Techniques

Reductions in densities of indicator organisms and pathogens were measured in maturation ponds receiving secondary effluents from trickling filter and activated sludge treatment works. Effluent detention times in the ponds were determined using dye tracing techniques and compared with nominal detention times calculated from pond volumes and effluent flow rates. Median detention times were substantially less than nominal times because of short circuiting due to pond design aspects and thermal stratification. Maturation ponds of 10 days median detention time were found to successfully disinfect a poor quality trickling filter effluent and were effective at removing parasite ova and reducing virus densities. Continued use of maturation ponds should be encouraged in developed and developing countries as they have low cost, operational, maintenance and skilled operator requirements and are an effective disinfection process. Pond designs should minimize short circuiting and thus the areal requirements of the ponds.

Many hydrogeological researches exist on the thermal springs of Turkey but limnological researches are very deficient. The results of the limnological research of the thermal springs in the basin of the meromictic lake Köyceğiz and Dalaman Basin are as follows; the thermal springs are of euthermal or chliarothermal types. In the thermal springs thermotolerant diatoms constituted the major plankton flora. Recommendations for the protection of thermal springs are given according to the results of this research.

Abstract. Flash floods are the result of very intensive rainfall events and karst plays an important role in flash floods. A study, using a hydrogeochemical approach, assessing data from several springs of different carbonate rocks in Western Turkey was made to classify karst aquifers' response to heavy rain events. Physicochemical measurements in wet and dry seasons and discharge rates were compared in order to explain aquifer characteristics. The groundwaters have pH values ranging from 6.3 to 8.9, temperatures (T) vary from 7 to 35 °C, and electrical conductivity (EC) values go from 140 to 998 μS cm/S. The groups that have high EC, high T, and low dissolved oxygen (DO) values represent the deep circulating waters. Low EC, low T and high DO values represent the shallow circulating waters. Low variations of the measurements in both the wet and dry seasons reveal that fracture permeability is predominantly controlled by diffused groundwater flow with low or high storage and conduit permeability with high storage. High variations of the measurements show conduit permeability with low storage but high transfer capability is predominantly controlled by turbulent groundwater flow which effective in flash floods.
