Summary Explanation and Background:
The purpose of this task order is to conduct third party sampling and performance measurement of six installed alternative septic upgrade systems using nitrogen reducing media below the drainfield. Sampling and performance measurement shall be conducted in accordance with the quality assurance project plan previously approved by the Board of County Commissioners and Florida Department of Health. The alternative media selected for evaluation had bench-scale data demonstrating it should meet or exceed the 65% nitrogen reduction standard set by the septic system overlay ordinance (2018-23) passed by the Board of County Commissioners in October 2018.
Currently, the only state-approved passive nitrogen reducing septic drainfield uses wood mulch, which has a limited lifespan currently estima...
