<br /> 2.0 EXPERIMENTAL PROCECURES
<br /> Tests were conducted to evaluate the effect of ozone and Peroxone in the subsurface
<br /> The results were compared to tests using inert nitrogen gas as well as untreated soil and
<br /> groundwater The procedures used are described
<br /> 2.1 Preparation of Soil and Groundwater
<br /> Ten 6-mch long soil cores (3 from IN, 3 from IP2, 2 from IP3, and 2 from EBI) and 5
<br /> groundwater samples (2 L each of IP-1-A, IP-1-B, IP-2-A, IP-2-B, and IP-3-B) were
<br /> received for testing September 29, 2004 and October 4, 2004 respectively Groundwater
<br /> from V-4 was received on November 13, 2004 Additional groundwater from V-4 and
<br /> MW-13 was received on March 29, 2005 MW-13 water was treated assumed to be a
<br /> background sample
<br /> Seven of the 10 soil cores were composited soon after receipt by sieving the soil to
<br /> remove particles > 4 mesh, then mixing by hand to obtain a visually homogeneous
<br /> sample This composite is hereafter referred to as COMP-7 soil The remaining cores
<br /> were stored undisturbed until November 22, 2004, when they were composited then used
<br /> to evaluate the fate of Cr(VI) This composite is hereafter referred to as COMP-3 soil
<br /> The groundwater samples received in September were composited by carefully pouring
<br /> the water into a 5-gallon bucket, gently mixing, then redistributing the water back into the
<br /> original sample containers, which had minimal headspace The groundwater was
<br /> composited because it carie from multiple wells at various depths that may have had
<br /> different initial characteristics This composited sample is hereafter referred to as IP
<br /> groundwater and was stored at room temperature (— 20°C) until needed The V-4
<br /> groundwater samples (received in November 2004) were also cornposited before use and
<br /> stored at room temperature (— 20°C) The resulting composite is hereafter referred to as
<br /> V-4 groundwater
<br /> COMP-7 soil was analyzed for TPHg, TPH-d, BTEX, MTBE, t-butyl alcohol (TBA),
<br /> acetone and metals (aluminum, antimony, arsenic, barium, beryllium, cadmium, calcium,
<br /> chromium, cobalt, copper, iron, lead, magnesium, manganese, mercury, molybdenum,
<br /> potassium, selenium, silver, sodium, thallium, tungsten, vanadium, and zinc)
<br /> Untreated IP groundwater was analyzed for TPHg, TPH-d, BTEX, MTBE, t-butyl
<br /> alcohol (TBA), acetone, metals (aluminum, antimony, arsenic, barium, beryllium,
<br /> cadmium, calcium, chromium, cobalt, copper, iron, lead, magnesium, manganese,
<br /> mercury, molybdenum, potassium, selenium, silver, sodium, thallium, tungsten,
<br /> vanadium, and zinc), alkalinity, bromate, bromide, chloride, conductivity, Cr(VI), nitrate,
<br /> oxidation reduction potential (ORP), pH, sulfate, and total dissolved solids
