Many Florida homes are not hooked up to a central
sewer system, but instead rely on individual septic tanks.
Unfortunately, the drainfields from these septic tanks, even if
properly maintained, seep nitrogen from human waste into surface
and ground waters. Too much nitrogen stimulates heavy growths of
algae that may kill aquatic plants and fish.
If you have a septic tank on your property, you are
responsible for its maintenance. The only way to avoid maintenance
is to see if you can hook up to your community's sewer system.
Otherwise, reduce the chance of nitrogen leaks through regular
maintenance: have the tank inspected every 2-3 years and pumped
out, if necessary; do not use caustic cleaning chemicals or
solvents that might destroy waste-reducing bacteria; and do not
plant trees or shrubs over a septic tank or drainfield.
