They are present in Lake Okeechobee and the Caloosahatchee (CE) and St. Lucie (SLE) estuaries and rivers, and they&#8217;re wreaking havoc on summer recreation and even the health of local residents.<\/span><\/p>\n<p><a href=\"https:\/\/www.fau.edu\/hboi\/meh\/hab.php\"><span style=\"font-weight: 400;\">Dr. Brian Lapointe<\/span><\/a><span style=\"font-weight: 400;\"> of<\/span><a href=\"https:\/\/www.fau.edu\/hboi\/\"> <span style=\"font-weight: 400;\">Florida Atlantic University&#8217;s Harbor Branch<\/span><\/a><span style=\"font-weight: 400;\"> has been researching HABs for decades.

So we get a lot of rainfall, a lot of runoff, and that&#8217;s kind of the hammer that brings the nutrients from the groundwater into surface waters like Lake Okeechobee.\u201d<\/span><\/p>\n<h3><span style=\"color: #808080;\">Rapid growth, unchecked pollution<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Reading much of the news coverage of the 2018 algal blooms, you might be tempted to believe that the growing population of the state isn&#8217;t much of a factor and that industrial and agricultural pollution are the main driving forces behind the HABs in the area. However, Dr. Lapointe&#8217;s research reveals that development and population growth are playing a crucial role in the pollution that feeds the HABs.<\/span><\/p>\n<p><div id=\"attachment_29951\" style=\"width: 610px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-29951\" class=\"size-large wp-image-29951\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2018\/08\/FL_HAB_Caloosahatchee-River-600x400.jpg\" alt=\"Florida\u2019s Algal Blooms\" width=\"600\" height=\"400\" \/><p id=\"caption-attachment-29951\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Nutrient pollution in marina on Caloosahatchee River near Cape Coral, 2005 (Credit: By John Cassani [Public domain], via Wikimedia Commons)<\/span><\/p><\/div><span style=\"font-weight: 400;\">\u201cNine hundred people a day move to Florida, and about 40 percent of them go on septic tanks,\u201d remarks Dr. Lapointe. \u201cWe have an unusually heavy reliance on septic tanks in Florida. It&#8217;s kind of a magic carpet for rapid cheap growth. Unfortunately, our aquatic ecosystems are also very sensitive to very low levels of nutrient enrichment from nutrients like nitrogen and phosphorus, and we&#8217;re seeing the chickens come home to roost now from decades of policies that have allowed nutrient pollution of our groundwater and surface waters.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Why is Lapointe so certain that agriculture and industry aren&#8217;t the real problems?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cWe take samples of the water and algae and we analyze it for nitrogen isotopes to identify the source of the nitrogen, whether it&#8217;s sewage or fertilizers or whatever,\u201d Dr. Lapointe describes. \u201cWe use not only the nitrogen isotopes but also human tracers like sucralose that tell us it&#8217;s not from the sugar plantation.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Dr. Lapointe refers to case studies in Florida, particularly in Tampa Bay, that prove the utility of taking a scientific approach to cleaning up sewage in urbanizing areas.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cYou can actually grow the population without these adverse consequences,\u201d comments Dr. Lapointe. \u201cThey used sound science and nitrogen removal from sewage to actually grow the population, and in the case of Tampa, millions of people came over recent decades while the Bay got better and better. Because they understood the science of the problem.\u201d<\/span><\/p>\n<h3><span style=\"color: #808080;\">Finding a scientific solution to a political problem<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The HABs are nothing new in Florida\u2014but they are a growing problem. This summer,<\/span><a href=\"https:\/\/floridadep.gov\/dear\/algal-bloom\/content\/emergency-authorizations-implement-measures-address-south-florida-algal\"> <span style=\"font-weight: 400;\">Florida Governor Rick Scott authorized emergency measures<\/span><\/a><span style=\"font-weight: 400;\"> that will be taken to counter the blooms. According to Dr. Lapointe, whether or not those emergency measures will be effective will depend largely upon whether they will be based on scientific evidence.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cWe have a number of environmental groups in Florida, and they blame big sugar, these farms south of Lake Okeechobee, for this problem,\u201d remarks Dr. Lapointe. \u201cBut it&#8217;s really not their fault. The water and the nutrients are coming in from the north of the lake, the Kissimmee River. What&#8217;s at the top of the Kissimmee River Basin near Orlando? Disney World. So, you know what&#8217;s coming down.\u201d<\/span><\/p>\n<div id=\"attachment_29949\" style=\"width: 610px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-29949\" class=\"size-large wp-image-29949\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2018\/08\/FL_HAB_lapointe_field-600x450.jpg\" alt=\"Florida\u2019s Algal Blooms\" width=\"600\" height=\"450\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_lapointe_field-600x450.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_lapointe_field-300x225.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_lapointe_field-768x576.jpg 768w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_lapointe_field-940x705.jpg 940w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_lapointe_field.jpg 1066w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-29949\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Dr. Lapointe in the field in the Florida Springs area. (Credit: Dr. Lapointe, https:\/\/hboihablab.weebly.com\/gallery.html)<\/span><\/p><\/div>\n<p><span style=\"font-weight: 400;\">The area north of the lake, surrounding Orlando, is one of the fastest growing areas in Florida\u2014a state that&#8217;s already<\/span><a href=\"https:\/\/countrydigest.org\/florida-population\/\"> <span style=\"font-weight: 400;\">one of the fastest growing in the US<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cIt resembles L.A. to me, it&#8217;s growing so fast,\u201d adds Dr. Lapointe. \u201cAnd like I said there are a lot of septic tanks there.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">During the many extreme weather and even during \u201cnormal\u201d but heavy rainfall events, a rush of water enters the Kissimmee River. That river was \u201cchannelized\u201d or straightened by the U.S. Army Corps of Engineers (USACE) so it could drain more quickly into Lake Okeechobee\u2014but this also destroyed the river&#8217;s natural filtration process. The USACE is now restoring part of the Kissimmee to provide more dynamic storage, but because 95 percent of the nutrient-rich water causing the blue-green algal blooms in Lake Okeechobee is coming from north of the lake, restoring the river alone won&#8217;t solve the problem.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cWhat they&#8217;re proposing as the solution is building a reservoir down south of the lake,\u201d explains Dr. Lapointe. \u201cWhen we get these major rain events, the lake rises too fast, and the Army Corps has to discharge water from the lake either to the Caloosahatchee which goes down to Fort Myers or to the St. Lucie River that goes down to Stuart, Florida on the East Coast. Building the southern reservoir will send the water south towards the Everglades in Florida Bay, essentially moving the problem somewhere else, rather than dealing with the source of the problem which is north of the lake.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In other words, source reduction is really what works most effectively\u2014unless you get lucky.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cI think we&#8217;re at a critical time here in the state of Florida, where to really get on top of this problem we really have to use sound science and not politics as usual which unfortunately has gotten us to where we are today,\u201d adds Dr. Lapointe.<\/span><\/p>\n<h3><span style=\"color: #808080;\">Preparing for Florida&#8217;s future<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">2018 may be a year of relative respite in terms of extreme weather events, but that isn&#8217;t going to make a long-term difference for the state&#8217;s HAB problem.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cWe might be spared [from major hurricanes] this year, but I think in the long run we&#8217;re likely to see more of these tropical storms in the future, and stronger storms,\u201d explains Dr. Lapointe. \u201cThat is the prediction with climate change, that we&#8217;re going to actually see increased frequency and intensity of these rain events which is like I said, the hammer.\u201d<\/span><\/p>\n<div id=\"attachment_29947\" style=\"width: 610px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-29947\" class=\"size-large wp-image-29947\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2018\/08\/FL_HAB_NOAAimages-600x445.png\" alt=\"Florida\u2019s Algal Blooms\" width=\"600\" height=\"445\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_NOAAimages-600x445.png 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_NOAAimages-300x222.png 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_NOAAimages-768x569.png 768w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_NOAAimages-940x697.png 940w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_NOAAimages.png 1059w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-29947\" class=\"wp-caption-text\"><span style=\"color: #808080;\">June 2018 NOAA satellite images depict the development of a bloom in Lake Okeechobee. (Credit: NOAA)<\/span><\/p><\/div>\n<p><span style=\"font-weight: 400;\">According to Dr. Lapointe, the increase in extreme rain events alone in the years to come is going to increase nitrogen loading in the water by 20 percent. Mitigating that 20 percent will require a reduction of the human nitrogen footprint by about 30 percent.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cWe have a framework, the total maximum daily load (TMDL) amounts that have been developed for different basins around Florida,\u201d remarks Dr. Lapointe. \u201cTo achieve those goals, we have to begin to reduce nitrogen in each of those basins for which there&#8217;s a TMDL, and we&#8217;re doing that through the basin management action plan (BMAP).\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The way to do this is to sever the head of the septic snake.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cI already explained the problem with septic tanks; we have too many of them in Florida,\u201d states Dr. Lapointe. \u201cIt&#8217;s ridiculous, really. One of the most significant things we could do to significantly reduce the nitrogen loads in the basins north of Lake Okeechobee and along the Caloosahatchee and the St. Lucie, would be to get rid of these septic tanks and implement septic sewer programs.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Septic sewer programs replace septic systems with municipal sewers and divert sewage to treatment plants. Treatment reduces nitrogen in the effluent from an average of 65 milligrams per liter to one milligram per liter.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cNow that tells you what the problem is, doesn&#8217;t it?\u201d Dr. Lapointe describes. \u201cIt&#8217;s a major source of the nitrogen fueling the algae blooms we are seeing, and it&#8217;s out of sight, out of mind, because people have septic tanks and they&#8217;re permitted by the state of Florida. It&#8217;s all underground, they can&#8217;t see it. And they are having a hard time believing that their septic tank is part of this problem. But that&#8217;s what the research is showing, and not just mine. And the more you look at it, the more dire the situation is.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Cost may be another reason some Floridians resist the idea of septic pollution as a driving force behind HABs.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cDon&#8217;t forget, it&#8217;s not free,\u201d remarks Dr. Lapointe. \u201cWe&#8217;re going to have to have to get our checkbooks out and actually pay to live in paradise. Paradise ain&#8217;t cheap. If you live here sustainably, you just have to pay for having a clean lake Okeechobee. All of us are going to have to pay. And you know human nature. A lot of people don&#8217;t want to pay.\u201d<\/span><\/p>\n<p><div id=\"attachment_29950\" style=\"width: 610px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-29950\" class=\"size-large wp-image-29950\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2018\/08\/FL_HAB_okeechobee-600x600.jpg\" alt=\"Florida\u2019s Algal Blooms\" width=\"600\" height=\"600\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_okeechobee-600x600.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_okeechobee-300x300.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_okeechobee-150x150.jpg 150w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_okeechobee-768x768.jpg 768w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_okeechobee-1536x1536.jpg 1536w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_okeechobee-2048x2048.jpg 2048w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2018\/08\/FL_HAB_okeechobee-940x940.jpg 940w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><p id=\"caption-attachment-29950\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Blue-green algae bloom on Lake Okeechobee, 2016.
