Due to these impacts, HABs can adversely affect various water uses, including drinking water, animal watering and recreational use. These blooms can also cause or contribute to numerous other water quality issues, including:<\/p>\n<ul>\n<li>Deoxygenation of water<\/li>\n<li>Accelerated eutrophication<\/li>\n<li>Emission of compounds that cause taste and odor<\/li>\n<li>Increased turbidity<\/li>\n<li>Discoloration<\/li>\n<li>Increased volatility in pH<\/li>\n<li>Mobilization of toxic metals from the sediment<\/li>\n<\/ul>\n<p>Data indicate that HABs are increasing in frequency and intensity around much of the world and there is a growing need to address these blooms in a proactive manner, particularly in areas where HABs are coupled with water scarcity or contamination challenges.<\/p>\n<p>Nutrient inactivation treatment has proved to be a successful mitigation approach . Following best practices in planning, implementing and monitoring can minimize or prevent HABs both now and for the future.<\/p>\n<p><a class=\"btn btn-primary\" href=\"https:\/\/www.trccompanies.com\/services\/engineering\/electrical-power\/power-academy\/contact\/\">Contact Us<\/a><\/p>\n                <\/div>\n                <div class=\"col-lg-4 columns js-animated-content animated-content\">\n                                        <div class=\"wysiwyg__links js-animated-content animated-content\">\n                        <div class=\"wysiwyg__links__top \">\n                                                        <h4>Related Services<\/h4>\n                                                                                    <ul class=\"js-animated-content animated-content\">\n                                                                <li><a href=\"https:\/\/www.trccompanies.com\/services\/environmental-assessment-permitting-and-compliance\/environmental-assessments\/biological-assessment\/\" target=\"_self\">Biological Assessment<\/a><\/li>\n                                                                <li><a href=\"https:\/\/www.trccompanies.com\/services\/regulatory-environmental-consulting\/environmental-assessments\/environmental-site-assessment\/\" target=\"_self\">Environmental Site Assessment<\/a><\/li>\n                                                                <li><a href=\"https:\/\/www.trccompanies.com\/services\/specialized-consulting\/sustainability-advisory-services\/\" target=\"_self\">ESG and Sustainability Advisory Services<\/a><\/li>\n                                                                <li><a href=\"https:\/\/www.trccompanies.com\/services\/remediation-and-materials-management\/pfas-and-emerging-contaminants\/\" target=\"_self\">PFAS and Emerging Contaminants<\/a><\/li>\n                                                            <\/ul>\n                                                    <\/div>\n                                                                        <div class=\"wysiwyg__links__bottom\">\n                            <a href=\"https:\/\/www.trccompanies.com\/services\/\" target=\"_self\">View All Services<\/a>\n                        <\/div>\n                                                                    <\/div>\n                <\/div>\n                    <\/div>\n\n            <\/div>\n<\/section>\n<!-- End Block: acf\/wysiwyg -->\n\n<!-- Start Block: acf\/wysiwyg -->\n\n<section class=\"wysiwyg section-padding bg-white-fog\">\n    <div class=\"container-fluid\">\n        \n        <div class=\"row\">\n                        <div class=\"col-lg-12\">\n                                                                                \n                                                <\/div>\n\n                                                                        <div class=\"col-lg-4 \">\n                                                        <div class=\"js-animated-content animated-content\">\n                                <h2>Cause of HABs \u2013 The Role of Internal Loading of Phosphorus from Sediments<\/h2>\n                            <\/div>\n                        <\/div>\n                                                                                <div class=\"col-lg-4 columns\">\n                                                        <div class=\"js-animated-content animated-content\">\n                                <ul>\n<li>HABs occur in waterbodies with high levels of phosphorus, which allows for rapid growth of algae and cyanobacteria.<\/li>\n<li>In many cases, bottom sediments contain high levels of phosphorus due to long-term accumulation from watershed sources.

In many cases, phosphorus release from the sediments is the primary driver of HABs in these waterbodies. Nutrient inactivation treatments, such as alum, reduce the amount of phosphorus released which can minimize or eliminate HABs for years. However, nutrient inactivation is not appropriate for every waterbody with recurring HABs.<\/p>\n<p>TRC\u2019s lake management experts can help you diagnose the drivers behind the HABs in your waterbody, determine if nutrient inactivation makes sense and, if so, lead the way in helping you design, permit and implement an effective treatment. We also have the expertise to assist you in HAB issue assessment, community outreach and risk communications and the implementation of other treatment and management approaches.<\/p>\n<p><a
