Addressing Septic Pollution: Insights from Merritt Island's Monitoring Initiative

Merritt Island in Brevard County has recently been in the news for its steps towards addressing the septic pollution problem that has been plaguing the area for years. Through a septic moratorium and an analysis spearheaded by Applied Ecology, the region has been able to develop interesting and visually representative data. This initiative, part of the Save Our Indian River Lagoon Project Plan, sheds light on how a similar approach could be beneficial for Indian River County (IRC).

The analysis in Brevard employed extensive predictive modeling with site-specific information for the watershed, aiming to determine the minimum buffer required to effectively shield the Indian River Lagoon from nitrogen loads emanating from septic systems. The employed model, ArcGIS-based Nitrate Load Estimation Toolkit (ArcNLET), was tailored with County-based input data to estimate ammonia and nitrate loads. This meticulous data analysis helped in understanding the extent of pollution, allowing for informed policy decisions.

The Merritt Island initiative underscores the importance of understanding the intrinsic issues associated with septic tanks, especially in areas where the water table is high and proximity to waterways is a concern. The reality is, no traditional septic tank, regardless of its age or condition, is exempt from contributing to nutrient pollution, particularly in environmentally sensitive areas. This isn’t about dictating actions to homeowners but rather about fostering awareness and education on the repercussions of septic systems on our water quality. A thorough grasp of how nutrients from septic tanks infiltrate our waterways, vividly illustrated through data, can be a potent tool for community education. Again, even a well-maintained septic tank can discharge detrimental nutrients into nearby waters, given the soil conditions and water table of an area. The table provided at the end of this article showcases how pollutants can travel up to 100 meters, albeit getting more diluted as they move farther from the source. By disseminating this kind of concrete information, we're not just building a well-informed community but also nurturing a collective resolve to protect our waterways. Transitioning towards cleaner water solutions informed by data, as seen in Merritt Island's endeavor, can significantly enhance our community's engagement in environmental preservation. By promoting a better understanding of the pollution dynamics associated with septic systems, we're laying a foundation for a more informed, collaborative effort towards safeguarding our local environment.

Take a moment and talk about the Florida Right to Clean Water initiative with someone you know. Explain why it matters to YOU that Floridians should have a right to clean and healthy waters -- greater than the "rights to pollute and destroy" special interests currently have. Explain why state agencies should enforce laws the way they should -- based on good science, serving the interests of FLORIDIANS. IRNA will be at several events in the next few weeks collecting petitions from attendees and we could use your help! Reach out to Karen Wynn at to sign up for a shift!
