    other industry organizations sponsored a research workshop to identify key research needs of the water softener and onsite systems industry The workshop participants discussed the state of the science and research on topics such as ion exchange wastewater characterization of systems with water softeners effects of chlorides on microbiological transformations including BOD removal nitrification denitrification and anaerobic processes interrelationships between salts septic tanks and biological processes and mono and divalent Cat Ions and their effect on settling Speakers included academics such as Dr JoAnn Silverstein from the University of Colorado Dr John Novak from Virginia Tech as well as experts such as Dr Phillip Pedros from F R Mahony Associates and Alan Rimer from Black Veatch Corporation The workshop also provided the participants with the opportunity to hear the perspectives of regulators such as Tom Konsler from Orange County North Carolina John Hayes from the State of Delaware and Maureen Tooke of the US EPA Finally participants also had the opportunity to hear from different industry representatives such as Terry Bounds of ORENCO Joe Harrison of the Water Quality Association and Tom Ferrero of the National Association of Waste Transporters The Workshop attendees identified and prioritized the following top five

    management of domestic wastewater A static flux chamber method was used to measure the emission rates of methane carbon dioxide and nitrous oxide gases from eight septic tanks and two soil dispersal systems A technique developed for the measurement of gas flow and concentration at clean out ports was used to determine the mass flow of gases moving through the household drainage and vent system There was general agreement in the methane emission rates for the flux chamber and vent system methods Several sources of variability in the emission rates were also identified The septic tank was the primary source of methane whereas the soil dispersal system was the principal source of carbon dioxide and nitrous oxide emissions Methane concentrations from the soil dispersal system were found to be near ambient concentrations similarly negligible amounts of nitrous oxide were found in the septic tank All emissions originating in the soil dispersal system were discharged through the building vent as a result of natural wind induced flow The gaseous emission rate data were determined to be geometrically distributed The geometric mean and standard deviation sg of the total atmospheric emission rates for methane carbon dioxide and nitrous oxide based on samples
