dc.description.abstract As a result of rapid growth in technology, efforts to remove pollutants from the natural environment have not been able to keep pace with the increasing amount of waste materials and a growing population that further aggravates the situation. This has resulted in the transformation of lakes and ponds into pollution depots. A pilot study for monitoring certain selected trace elements entering and leaving YorkPrairie Creek Pond, situated inside the campus of Ball State University, was undertaken with the view to establishing whether or not this pond has been polluted, like many lakes and ponds, by metal corrosion, engine exhaust gases, and runoff from fertilizers and streets.This investigation involved sampling pond waters at two sites, viz., Influx surface and Effluent surface. Samples were collected once daily at the same time over a total time period of 23 days. Each sample was analyzed, in duplicate, for the heavy metal cations iron, lead, and cadmium, and for the inorganic anions nitrate, orthophosphate, and chloride. Metals were analyzed by atomic absorption spectrophotometry (A. A. S.), while titrimetric and cotorimetric procedures were utilized for the anion analyses.Results have indicated that iron and chloride are the most abundant of all analytes. Precipitation tends to Increase concentrations of analytes in general, possibly due to increased runoff and the lowering of the pH of these waters; leading to increased elemental release into solution. The relative responses of the analyzed ion levels in pond influx and effluent waters have been shown to be similar although their levels were significantly different.Analyte levels were found to be generally higher in effluent than in Influx waters; only chloride was found to depart from this general behavior. This finding led to the conclusion that the selected Ions, with the exception of chloride, tend not to accumulate in the waters of the pond but rather to escape with its effluent. This conclusion is subject to modification by future researchers, to whom the author has recommended a more expanded sampling program that would include the surface and sediment of the pond's interior since the nature of the results (especially for Pb and Cd) would seem to indicate not only that the pond does not exhibit thorough mixing of its constituents (homogeneity) but also the presence of an active remobilization process within its interior.
