<br />1) Stoichiometry or chemical 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 H2O2
<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 injection. The following general mineral suite should
<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 11202injection. The following general mineral suite should be evaluated: aluminum, antimony,
<br />arsenic, barium, beryllium, cadmium, calcium, chromium (III and VI), cobalt, copper, iron, lead,
<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.injecting 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 injection of the H2O2 solution,
<br />and the rationale for the estimate.
<br />6) Provide estimates of changes in pH in groundwater and the radius of influence for the H202injection.
<br />If the studies indicate that the proposed injection will remediate the hydrocarbons and will not adversely
<br />affect water quality, we can determine the applicability of WDRs and the appropriate fining fee.
<br />If you have any questions please contact me at (916) 464-4615 or bartonj6a4b5s.swrcb.ca.gov.
