<br /> 1) Stoichiometry or chenucal equations with concentrations in moles for the reaction between the soil
<br /> and groundwater and the H2O2 solution '
<br /> 2) Provide results of a leachability test of native soils, to determine the potential effects from the 142O2
<br /> solution General minerals analyses should be conducted to evaluate if naturally occurring minerals
<br /> will move into solution as a result of the H2O2 infection The following general mineral suite should t
<br /> be evaluated aluminum,antimony, arsenic, barium,beryllium, cadmium, calcium, chromium (III and
<br /> VI), cobalt, copper, iron, lead,magnesium, manganese, mercury, molybdenum, nickel,potassium
<br /> selenium, silver, sodium, thallium, tungsten, vanadium, and zinc
<br /> 3) Provide results of general minerals analyses of the groundwater Results from this analysis should be '
<br /> used to evaluate if naturally occurring minerals will precipitate out of the groundwater as a result of
<br /> the H2O2 infection The following general mineral suite should be evaluated aluminum, antimony,
<br /> arsenic,_barium,_beryllium,-cadmium,_calciuin;_chroinium(III-and VI),-cobalt,—copper;iron;lead, r�
<br /> magnesium,manganese,mercury, molybdenum,nickel,potassium, selenium, silver, sodium,
<br /> thallium, tungsten, vanadium,and zinc
<br /> 4) Provide an estimate of the mass of other constituents/parameters, including Electrical Conductivity, '
<br /> chlorides,sulfides,etc which will be released into the aquifer as a result of ejecting the H2O2
<br /> solution, and the rationale for the estimate
<br /> 5) Provide an estimate of the mass of TDS that will be mobilized by the infection of the H2O2 solution, '
<br /> and the rationale for the estimate
<br /> 6) Provide estimates_of_changes m_pH-in groundwaterand_the radius of- uence for-the-H2O2-infection
<br /> If the studies indicate that the proposed mlection will remediate the hydrocarbons and will not adversely ,
<br /> affect water quality, we can determine the applicability of WDRs and the appropriate fining fee
