Solving A Taste and Odor Problem Step By Step
2014-05-22 13:31:36| pollutiononline Downloads
By Terry Keep of TrojanUV, Said Abou Abdallah of Arcadis, and Dr. Dean Reynolds, Department of Water Treatment City of Alliance, Ohio The City of Alliance Ohio’s water system has experienced annual Taste and Odor (T&O) events since the mid 1950’s, when the first of two reservoirs, Deer Creek Reservoir, was placed into service. Nutrient contaminants, in particular phosphorous, in the watershed accumulate in the reservoirs causing algal blooms. The blue-green algae, also known as cyanobacteria, produce two aesthetically-offensive secondary metabolite compounds, 2-methyisoborneal (MIB) and trans-1,10-dimethyl-trans-9-decalol (Geosmin). Although both compounds occur in high concentrations in the reservoirs, frequent testing showed that MIB is the primary compound causing T&O problems in the city’s drinking water. MIB can be detected by a few very sensitive persons as low as 7 ng/L (parts per trillion, ppt), but most people cannot detect MIB until it is greater than 20 ppt. A particularly bad T&O event occurred in the winter of 2009 when the MIB level reached 340 ppt. The City was flooded with complaint calls. The Alliance Water Treatment Plant (WTP) fought the problem with the available treatment processes. The main process used for removing MIB was powder activated carbon (PAC). In addition, 24 in. of granulated activated carbon (GAC) capping the eight filter beds in the plant had shown some seasonal success at removing MIB. Concentrations for a typical 12-month period are presented for 2010 and 2011 in Figure 1. The highest MIB concentration during that time was 1100 ppt.
California first step toward curtailing water rights

Reuters: Some farmers and community water districts in drought-hit California could soon face limits on their ability to use water from strained streams that flow into the Sacramento River. The California Water Resources Control Board adopted regulations on Wednesday to limit water use during summer months, the driest season and the time of year when farmers are most likely to need water to irrigate their crops. "Due to severe drought conditions, immediate action is needed," said Dan Schultz, acting...

Abbott out of step on climate change, says Prof Jeffrey Sachs
2014-05-21 20:29:00| Climate Ark Climate Change & Global Warming Newsfeed
Sydney Morning Herald: Australia's reversal on climate change action will ultimately not stick because the rest of the world will make clear that it is unacceptable, globally renowned economist Professor Jeffrey Sachs says. Speaking to Fairfax Media, Professor Sachs said the extreme shocks and pain of climate change were now being felt across the planet and governments acting in an ''anti-scientific perspective or an extraordinarily short-term perspective'' will be surprised by the response from other countries. ''This...
