  • GRA-Cast Web Seminar on 3/20/2013: Tracers and Groundwater Recharge
    analyses to assess rates locations timing and controls on denitrification during infiltration and groundwater flow Our studies show enormous variability in space and time in the physical and biogeochemical behavior of infiltrating water Simultaneous and co located sampling and measurements reveal consistent relations between infiltration and denitrification rates Results from this study raise intriguing questions about recharge processes in general and suggest that MAR systems might be operated for simultaneous improvements to both water supply and water quality 3 Geochemical Imaging of Flow and Transport down gradient from an Artificial Recharge Facility Orange County CA 30 min Jordan Clark PhD Critical for assessing the potential impacts of managed aquifer recharge MAR operations on water quality is detailed knowledge of groundwater dynamics near spreading areas Geochemical tracer techniques including stable isotopes of water tritium helium 3 T 3He dating and the addition of trace gases in controlled experiments are ideally suited for these investigations This presentation will present series of experiments that were conducted using these tracers near the MAR facilities in Northern Orange County CA Here approximately 2 5 x 108 m3 200 000 acre ft of surface water are recharged annually to the groundwater basin T 3He ages show that most of the relatively shallow groundwater within 3 km of the recharge facilities have ages less than 4 years further down gradient ages increase reaching 20 years at distances more than about 6 km and depths greater than 100 m Far from the spreading area in the confined portions of the aquifer there is little evidence for young tritium rich groundwater Gas tracer experiments using sulfur hexafluoride SF6 and xenon isotopes were conducted from the Santa Ana River SAR and two spreading basins Kraemer Basin and Anaheim Lake These tracers were followed in the groundwater for up to 7 years SF6 from the SAR allowing subsurface flow patterns and flow times to selected wells to be quantified Results demonstrate that the mean horizontal flow velocity range between 0 4 and 2 9 km yr 1 It is likely that the tracers were moving primarily through the most conductive layers and thus these velocities do not represent bulk flow within all layers The leading edge of the tracer plume moved at velocities about twice as fast as the center of mass The former velocities are important when considering the potential transport of microbes and other time sensitive contaminants because they reflect the fastest paths in the aquifer These velocities cannot be easily determined with other methods showing the importance of geochemical techniques evaluating artificial recharge sites By combining T 3He dating with gas tracer experiments groundwater flow was imaged with time scales on the order of weeks to decades with spatial scales of 100s of meters to kilometers 4 Question Answers 25 min Moderated by Tom McCarthy PE PG SPEAKER BIOS Andrew T Fisher PhD is a professor of Earth and Planetary Sciences at the University of California Santa Cruz with interests in surface water groundwater interactions water resources managed

  • GRA-Cast Web Seminar on 4/23/2013: Groundwater Recharge Outside of California
    min Bart Weiss PG West Central Florida has exhibited declining groundwater levels in the Upper Floridan aquifer over the last 50 years in the area of southern Hillsborough County and western Polk County These water level declines have caused saltwater intrusion along the coastal area of Hillsborough County The Southwest Florida Water Management District District designated the Southern Water Use Caution Area SWUCA in this area to limit additional groundwater withdrawals and implemented a recovery strategy to mitigate the Most Impacted Area MIA that exhibited the highest decline water levels The District implemented a regulatory water level mitigation policy that would allow groundwater mitigation offset credits to be earned for up to 90 percent of the regional water level improvements within the SWUCA which may be used to develop future water supplies further inland Hillsborough County has taken the regional initiative to be a leader in addressing this water resource mitigation issue by further evaluating aquifer recharge to maximize the use of their seasonally available reclaimed water The County initiated an aquifer recharge pilot project the South Hillsborough Aquifer Recharge Program SHARP to beneficially utilize available reclaimed water as a saltwater intrusion barrier The benefits of coastal aquifer recharge include creating a saltwater intrusion barrier system to mitigate the advancement of saltwater inland the reduction of reclaimed water discharges and the improvement of water levels in the SWUCA and MIA Finally water withdrawal credits mitigation offsets will be obtained from this recharge system and be used to provide a higher reliability to the County s reclaimed water system during the dry months or used to develop additional inland groundwater withdrawals currently not allowed today 4 Phoenix s ASR Well Glass Beads Versus Silica Sand Filter Pack Is There a Difference 20 min Gary Gin RG City of Phoenix has successfully installed developed and pump tested an 18 inch diameter Aquifer Storage and Recovery ASR well with natural silica sand mesh 6 x 9 and glass beads Sigmund Lindner Type S 2 4 2 9 mm Glass beads utilized as a filter pack media in water supply wells in Europe has demonstrated higher collapse strength energy savings in pumping and reduced clogging versus natural silica sand filter packs Phoenix s ultimate goal is to pilot these glass beads under recharge operations to determine the impacts to recharge operations i e reduced backwash operations duration and rates of recharge sustainable over time and well clogging i e duration and ease of unclogging the well The installation of these two filter pack types in the ASR well was to determine developmental and operational pumping and recharge difference In this presentation we will summarize development pump testing and spinner log activities and findings Ultimately we will be testing the long term viable and potential cost savings of utilizing glass beads as a filter pack media in water supply and ASR wells 5 Question Answers 25 min Moderated by Tom McCarthy PE PG SPEAKER BIOS Dave Nazy LHG is currently the lead groundwater specialist in
