Title: Caffeine as a marker for sewage contamination of Wilgreen Lake
Project Type: Research

End Date: 2/28/2011
Congressional District: KY Sixth
Focus Categories: Wastewater, Water Quality, Methods
Keywords: waste water effluent, anthropogenic marker

Abstract: This study will attempt to clarify the contribution of septic system waste in the nutrient impairment of Wilgreen Lake. Water samples will be collected at various depths from selected sites in the lake and its tributaries. Caffeine does not occur naturally in the watershed and there are no industries that produce caffeine waste in the watershed, so its presence can only come from human activity. The objective of this project is to determine if caffeine is present at higher concentrations near suspected septic system inflows.
