Water Quality Woes in Southwest Florida Linked to Seeping Septic Systems
From fecal bacteria to blue-green algae to red tides, Southwest Florida’s water quality has declined as its population has increased. Multiple lines of evidence from a multi-year microbial source tracking study points to septic systems as a contributing source for this decline. The study is one of few to connect downstream harmful algal blooms with nutrient loading from upstream septic systems. These water quality issues are caused by aging septic systems installed in high densities in areas with shallow water tables. Septic systems may actually be sitting in groundwater during certain times of the year, which means that they cannot function properly.
