  • Study Reveals Climate Change Impacts On Buzzards Bay
    runoff Excess nitrogen also boosts algae growth What we re seeing in the long term data is that the same levels of nitrogen in the system results in much more algae growth than it did two decades ago Rheuban said This increase in algae growth and chlorophyll means that water quality is worse for the same amount of nitrogen which has big implications for water quality targets and clean up plans Identifying and understanding how different ecosystems respond to climate change will aid in future monitoring and clean up efforts as coastal communities prepare to adapt This research is part of multi pronged project funded in 2014 by the John D and Catherine T MacArthur Foundation aimed at partnering with local organizations to develop science based climate change solutions for coastal communities Summer Snapshots Over Time Every summer since 1992 volunteers working with the Buzzards Bay Coalition have headed out to their local beaches and docks to help monitor the health of the bay At sampling sites from Westport to the Elizabeth Islands trained citizen scientists gather samples and test temperature salinity water clarity and dissolved oxygen at the same locations every five days from late May through September In July and August volunteers also collect water samples that are taken to the Marine Biological Laboratory where they are analyzed for nitrogen phosphorus and chlorophyll The Baywatchers program has amassed more than two decades of data that has been a valuable resource over the years not only to the Coalition s education and outreach efforts but also to agencies that monitor water quality and draft clean up plans The data has been used by every level of government to make decisions about the management of waterways from deciding which waters are impaired to determining how much nitrogen a specific estuary can handle said Rachel Jakuba PhD science director for the Buzzards Bay Coalition and a coauthor of the paper This is the first time that over 20 years of the monitoring data has been analyzed for long term trends and patterns in particular with a focus on climate change First researchers looked at which locations and sites had the most consistent data over the 22 year period from 1992 to 2012 and then divided those into 17 distinct embayments see accompanying map for sites We analyzed the data on an embayment by embayment scale Rheuban said The degree of pollution in each embayment is very different and that has to do with a number of different factors levels of development whether there s agriculture or urbanization nearby For example expanded sewering of larger towns on the west side of the bay has helped reduce excess nitrogen from reaching nearby waterways more than sites along the Cape Cod side of Buzzards Bay that do not have such infrastructure already in place We don t see nitrogen increases across the board Rheuban said But what we do see in the analysis of the data is an increase in temperatures and chlorophyll concentration

  • Des Moines Pours 15 Million Into Nitrate Removal
    Works paid a hefty tab for denitrification last year The utility said it shelled out 1 5 million to remove nitrates from the water supply in 2015 according to KCCI It s one more sign of the way farm run off is stressing the water system in Iowa The special facility used to remove it from the water operated for a record 177 days last year The previous record was 106 days set in 1999 KCCI reported Water Works officials said the costs and risks of meeting drinking water requirements for nitrate are increasingly high as Iowa s surface waters demonstrate dangers levels of pollutants Water Works serves about 500 000 customers The utility said in a statement The increase in river nitrate levels is attributable to upstream agricultural land uses with the largest contribution made by application of fertilizer to row crops intensified by unregulated discharge of nitrate into the rivers through artificial subsurface drainage systems Bill Stowe CEO and General Manager Des Moines Water Works weighed in Iowa s political leadership with influence from industrial agriculture and commodity groups continue to deny Iowa s water quality crisis he said in a statement Defending the status quo avoiding regulation of any form and offering the illusion of progress and collaboration places the public health of our water consumers at the mercy of upstream agriculture and continues to cost our customers millions of dollars The utility anticipates the need to upgrade its infrastructure to contend with the problem It plans to spend 80 million for new treatment equipment including denitrification technology The utility is also trying to hold upstream polluters accountable Des Moines Water Works filed suit in March claiming the boards of supervisors of Buena Vista Sac and Calhoun counties serving as trustees of the drainage districts within their

  • Poor Algal Bloom Outlook For Lake Erie
    Lake Erie s algae problem A new study points to climate change as a primary factor and it said that pressure will not relent any time soon By the latter half of this century toxic algal blooms like the one that cut off drinking water to the city of Toledo in 2014 will no longer be the exception but the norm a study suggests While researchers have long suspected that climate change will lead to stronger and more frequent blooms a new fusion of climate models and watershed models has proven those suspicions right For Lake Erie at least the number of severe blooms will likely double over the next 100 years an announcement from Ohio State University said A pair of scientists recently presented these predictions in San Francisco at the American Geophysical Union s annual conference the Block News Alliance reported The presentation by Noel Aloysius a postdoctoral researcher in OSU s aquatic ecology laboratory and Hans Paerl a distinguished professor at the University of North Carolina Chapel Hill hit on familiar calls for tighter controls on farm fertilizers and other forms of nutrient runoff but also underscored the complexity of the problem as Earth s climate continues to warm the report said Around 400 000 residents in Toledo were unable to use their water for over two days due to toxic algae contamination last year CNN reported One of the most pressing causes is farm run off At a House Energy and Commerce subcommittee hearing on cyanotoxins John Donahue president of the American Water Works Association explained this factor There is no uncertainty about one critical aspect of the problem It is always associated with amounts of nitrogen and phosphorus in the water Donahue said per Roll Call Although each watershed is unique and has its own

  • PENETRON Boosts Moorefield Wastewater Treatment Plant’s Efforts To Clean Chesapeake Bay
    Treatment Plant replaces four plants that were previously under notice of environmental violations by the state Now this single larger plant provides the capacity and efficiency needed to serve residents and businesses across the entire western part of Hardy County where the South Branch of the Potomac River flows through a wide valley on its way to Chesapeake Bay The new facility marks a significant milestone in the headwater state s efforts to curb pollution and improve water quality Now in full operation the plant removes 90 000 pounds of nitrogen and 93 000 pounds of phosphorous from West Virginia wastewater every year According to best current estimates the Moorefield plant will take care of 50 65 of West Virginia s total commitment to reduce nutrient pollution in the Chesapeake Bay watershed adds Christopher Chen Director of The PENETRON Group INNOVATIVE TREATMENT PROCESS The Moorefield facility uses an innovative advanced nutrient waste water treatment process to treat 4 1 million gallons of wastewater per day This system exposes the incoming wastewater to nutrient hungry microbes that feed on nitrogen and phosphorous The resulting sludge modified without the addition of chemicals is turned into compost on an adjacent site rather than trucked off to the local landfill Essentially much of the waste going into the plant is generated by a local chicken processing company this is then treated and converted to compost adds Mr Chen The resulting compost is then sold to farmers without adding to the area s landfill PENETRON ADMIX PART OF THE SOLUTION Using an innovative precast post tensioned concrete tank design the process used at the Moorefield plant features an oxidation ditch with two primary clarifiers two final clarifiers a filter tank building a pump station and a leachate storage tank PENETRON ADMIX was specified for the

  • EPA Makes Major Move Toward Regulating Cyanotoxins
    entries on the U S EPA s list of substances it plans to study as a precursor to regulatory action In December the agency announced which substances it will study between 2018 and 2020 The contaminants it chose to investigate include ten contaminants created by algal growths in water sources known as cyanotoxins two metals eight pesticides three acid groups of disinfectant byproducts three types of alcohols and three semivolatile organic compounds Crain s Detroit Business reported Meanwhile the agency has also named some substances that it has decided not to regulate Those include dimethoate 1 3 dinitrobenzene terbufos and terbufos sulfone The Hill recently reported The backdrop is this per Crain s Detroit Business The Safe Drinking Water Act requires EPA to identify no more than 30 unregulated contaminants to monitor study and determine whether they should be regulated every five years These contaminants are ones that are not regulated but are known or expected to be present in drinking water This list of substances known as the Contaminant Candidate List CCL identifies contaminants that may possibly have negative health effects Cyanotoxins which are produced by blue green algae were already on the government radar because they pose a threat to drinking water resources In Toledo OH last year a ban on water use prevented around 400 000 residents from using their faucets for over two days amid toxic algae contamination CNN reported Where does the blue green algae problem come from At a House Energy and Commerce subcommittee hearing on cyanotoxins John Donahue president of the American Water Works Association explained the origin of the problem There is no uncertainty about one critical aspect of the problem It is always associated with amounts of nitrogen and phosphorus in the water Donahue said per Roll Call Although each watershed
