  • Algae Study Upsets Old Nitrogen Ideas
    Measurement Products Aclara Jacobi Carbons Endress Hauser Inc KROHNE Inc Kaeser Compressors Inc Emerson Process Management Rosemount Analytical Degremont Technologies Brentwood Industries View All Providers News Feature December 8 2015 Algae Study Upsets Old Nitrogen Ideas By Sara Jerome sarmje A new study could upset some of the conventional wisdom around algae growth and nutrient management in freshwater systems Phosphorus limitation has been regarded as the rule in freshwater systems when it comes to managing algae according to the study published in the scholarly journal Hydrobiologia But maybe that s not the best approach The nutrient phosphorus has long been regarded as the key to algal growth in freshwater systems However our results show that both phosphorus and nitrogen are equally important for growth of algae study authors Stefanie Mueller and Simon Mitrovic of Sydney s University of Technology explained in a statement Under regular conditions sediments play an important role in removing nitrogen from the water limiting algal growth Our research shows however that under low oxygen conditions sediments release considerable amounts of nitrates which can spark significant increases in algal growth they continued The authors say their study suggests shifts in typical algae management practices The findings mean water reservoir management needs to take into account the amount of nitrogen the sediments in Grahamstown Dam contribute to water column concentrations when setting limits for concentrations of nitrogen pumped into the lake the authors said Algae can pose major challenges to the effective operation of drinking water facilities Toledo OH banned water use for over two days last year due to toxic algae contamination CNN reported Cyanotoxins which are produced by blue green algae are on the EPA s Candidate Contaminant List 3 which enumerates harmful pollutants for potential regulatory action For similar stories on preventing algal bloom visit

  • Fox Metro Water Reclamation District Prepares To Meet Revised Illinois EPA Guidelines
    Fox Metro currently provides advanced high efficiency wastewater treatment for nearly 300 000 residents of Oswego Aurora Montgomery North Aurora Sugar Grove and portions of Batavia and Yorkville Though Fox Metro meets and exceeds current wastewater requirements the IEPA s recently revised guidelines require Fox Metro to further improve its award winning wastewater treatment facilities and enhance its ability to process phosphorous To comply with these unfunded mandates and upgrade aging infrastructure Fox Metro will build a new South Plant facility on existing District owned land After opening the project for public consideration Fox Metro s Board of Trustees selected the contractor with the most comprehensive and lowest cost bid River City Construction LLC to manage the construction of the new South Plant The water that Fox Metro discharges into the Fox River is already cleaner than the existing river water but the EPA has tasked the facility with reducing the level of phosphorous in the river by 2019 Phosphorus enters the watershed system through fertilizer runoff from farms and lawns and from human waste through wastewater which Fox Metro then receives and treats Within four years the new plant will eliminate 67 percent of phosphorus in Fox Metro s discharged water Phosphorus is a nutrient that depletes dissolved oxygen in water and may cause offensive conditions such as algae blooms The Fox River is part of the Mississippi River watershed the fourth largest river system in the world which flows into the Gulf of Mexico There impaired water contributes to Gulf Hypoxia or low oxygen zones The water in these dead zones does not contain enough dissolved oxygen to support marine life Removing more phosphorus from all Mississippi River tributaries may help alleviate Gulf Hypoxia and improve the ecosystem for aquatic plants animals and other organisms within the Fox River and the entire Mississippi watershed To comply with the IEPA s revised guidelines Fox Metro secured a 92 million State of Illinois Revolving Loan at a rate of 1 85 percent The Board has ensured that this loan will be repaid with user fees as part of planned incremental rate increases This will cost the average family of four about 16 50 per year or 1 38 per month less than a cup of coffee Though the Illinois EPA requires us to build this new plant the Board carefully considered this project to guarantee we can responsibly both environmentally and fiscally upgrade aging infrastructure add natural beauty and greenery to the area and meet new safety and environmental compliance standards said Tom Muth manager of the Fox Metro Water Reclamation District The new building project will benefit the Fox River Mississippi River and Gulf of Mexico for generations to come Fox Metro designed the plant to offer major advantages for minimal cost to each user as the District improves Fox River water quality for future water consumption by local communities Construction will begin in early 2016 the South Plant will be operational by late 2018 About Fox Metro Water

  • Urban Trees Provide Pollution Solution
    regular tap water The stormwater contained high levels of nutrients such as nitrogen and phosphorus High levels of these nutrients are typically present in stormwater in part because of fertilizer runoff Researcher Liz Denman now a member of the Landscape and Urban Design group at VicRoads explains that high levels of nitrogen and phosphorus can quickly go from nutrient to contaminate The levels stimulate algal blooms or higher than normal algae content in water bodies Algae consume oxygen in the water especially as they die and decompose They also block the sun from reaching areas below them upsetting the natural state of the water body The lower oxygen levels can result in fish deaths a loss of biodiversity in the waters and dead zones Some Australia states use mandates as a response The planning provisions in the Australian state where I live have a clause that relates to water management in residential subdivisions she adds This mandates targets for pollutant load reductions In most cases these guidelines require the incorporation of water quality treatment systems Through the 13 month experiment the group measured how well the different tree species grew when watered with stormwater They also looked at how well the trees took extra nutrients out of the stormwater The trees studied were from four species red box brush box white bottlebrush and oriental plane All four species receiving stormwater grew significantly larger than those receiving tap water demonstrating they all have the potential to thrive under urban conditions Additionally the results showed the trees are good at unpacking nutrients from stormwater Scientists collected the water that drained from the bottom of the experimental pots for a period of two hours after watering This water contained fewer undesired nutrients when it came from the planted soils The unplanted soils actually
