Using Macroinvertebrates as Indicators of Septic Tank Density

Learn about a groundbreaking research presentation from the Georgia Water Resources Conference examining how macroinvertebrate communities can indicate septic system impacts on water quality. Explore an 11-minute analysis of the Mulberry River Watershed study that investigates the relationship between septic tank density and freshwater pollution through macroinvertebrate monitoring. Discover how researchers assessed eight first-order streams with varying septic system densities using biological indexes like Hilsenhoff, EPT, and Margalef's richness. Examine findings that reveal direct correlations between septic system density and reduced macroinvertebrate diversity, while also uncovering surprising results about water quality near sewer lines. Gain insights into how on-site sewage management systems affect water quality and aquatic ecosystems in residential developments across Northeast Georgia.
