<br /> intervals to meet the current requirements of the CSJ-PHS and State for underground tank
<br /> petroleum releases The data collected in this periodic monitoring program can be used to track
<br /> hydrocarbons in groundwater
<br /> We also recommend that monitoring for biologic parameters be added to the monitoring program
<br /> to estimate biologic activity (i e , dissolved oxygen, pH, ferrous iron, sulfate and nitrate,
<br /> Wiedemeier and others, 1995) This will establish a baseline to estimate the biologic
<br /> degradation activity inferred and gauge selected future biologic monitoring parameters for the
<br /> site monitoring program Depending upon the results of the oxygen content of water, Wright
<br /> may add an oxygen carrier to aid in-situ degradation of the fuel (by biostimulation), pending
<br /> the approval of CSJ-PHS Wright will prepare a monitoring well installation and monitoring
<br /> workplan for CSJ-PHS review prior to starting this work, and will continue with currently
<br /> scheduled groundwater monitoring
