Q-6 How familiar were you with the problem of increased Nitrates in the Ichetucknee before reading this questionnaire? O Very Familiar O Somewhat Familiar O Not Familiar Q-7 How important is it to you to protect Ichetucknee Springs from nitrate pollution? O Very Important L Important 0 Somewhat Important D Not Important What are Septic Tanks? * Scientific studies have shown that there are unnaturally high levels of nitrate in the Ichetucknee. * The excessive nitrate levels in the Ichetucknee can cause dense growth of algae that smothers the native eelgrass and creates floating mats on the surface. The increased amounts of algae reduce water clarity which detracts from the snorkeling and scuba diving experience. * Certain varieties of noxious algae pose a health risk for swimmers and tubers that are allergic to it. * Excessive nitrates can have negative effects on habitat for aquatic turtles, crawfish, and other species of wildlife. * Several of scientific studies have shown that one of the major sources of nitrates in the Ichetucknee is septic tanks in the surrounding area. Septic tanks are used by households that are not connected to a city's municipal sewer system, for waste disposal.
