  • GRA Urges Governor to Uphold 2002 MtBE Phase Out Deadline
    Groundwater Resources Association of California GRA issued a letter to Governor Davis requesting that the original deadline be maintained Citing the enormous threat posed by MtBE to water resources MtBE has been detected in groundwater at thousands of gasoline stations and also in private and municipal water supply wells across the state GRA president Jim Carter urged Governor Davis to uphold his 1999 Executive Order that calls for MtBE removal from gasoline by December 31 2002 GRA endorsed Governor Davis Executive Order by adopting a resolution in January 2000 requesting an immediate ban on the fuel additive MtBE Further Carter pointed out that every gasoline facility with MtBE is a threat to water resources and drinking water sources due to the significant potential for spills and undetected releases and MtBE s unique characteristics The continuing contamination risks and staggering costs to clean up MtBE in soil and groundwater dictate adherence to the original phase out schedule GRA is a statewide organization of 750 groundwater professionals that is dedicated to resource management that protects and improves groundwater GRA and its members are on the forefront of observing and understanding the severity of MtBE impacts to California s water resources and are

  • GRACast Web Seminar on 1/15/2014 -- 1,4-Dioxane and Urban Runoff as a Potential Source of Emerging Contaminants
    drinking water supplies while simultaneously solving problems associated with wet weather flows As a result several regions are pursuing efforts to capture and recharge groundwater Currently water quality issues associated with urban runoff is limited to regulated stormwater contaminants many of which have been selected on the basis of their potential impacts to aquatic ecosystems If urban runoff contains unregulated contaminants at concentrations that pose potential risks to drinking water supplies it may be necessary to develop strategies for controlling contaminant sources or to add treatment systems to remove the contaminants prior to discharge This talk will address organic contaminants that may pose concerns for urban runoff recharge programs and present options for minimizing risks to water supplies 3 Questions Answers 10 min 4 Characterization and Treatment of 1 4 Dioxane in Groundwater 30 min Dr Shaily Mahendra University of California Los Angeles 1 4 Dioxane a probable human carcinogen is emerging as a contaminant of concern in groundwater resources Improper practices during manufacturing use and disposal of solvents have resulted in the contamination of groundwater with 1 4 dioxane While biodegradation of 1 4 dioxane has been previously reported in a number of laboratory studies reliable analytical tools to assess natural attenuation and bioremediation in the field are lacking We recently developed a novel Compound Specific Isotope Analysis CSIA method for determining the enrichment of 13C in 1 4 dioxane Pseudonocardia dioxanivorans which can grow using dioxane as its only source of carbon and energy was isolated and characterized in our previous work The role of monooxygenase enzymes in catalyzing dioxane degradation was confirmed using several independent lines of evidence and biochemical degradation pathway was described Recently the genome of P dioxanivorans assembled and annotated in collaboration with UC Berkeley and DOE Joint Genome Institute revealed multiple monooxygenase genes
