<br /> The purpose of this uoric f,s to anaiyze samples of soil and ground water
<br /> collected from locations nearby the former tanks. These locations will be
<br /> selected 'to Further evaluate the extent of the hydrocarbons reportedly
<br /> observed durjjg tank removal. The proposed work is as follows:
<br /> o Drilling of four soil borings for thoY purpose of obtaiting soil
<br /> Jawn, lea to be analyzed in the field via gas chromatography, and
<br /> i
<br /> furLhdr testing by Bio National Corporation;
<br /> I
<br /> y
<br /> o Conversfon cf _`our soil borings to 7
<br /> g ground water observation walls 'f
<br /> for the purpose of obtaining water samples for analysis at
<br /> Fireman's Fond Laboratories of petalvma, California; and
<br /> o Preparation Of a letter report summarizing the results if the
<br /> i
<br /> investigation.

<br /> The purpose Of the investigation is cc:
<br /> a Furthdr evaluate the concentration of hydrocarbons in the soil; I
<br /> V
<br /> o Further evaluate the vertical and lateral eXtet)t of the observed
<br /> contamination; and 1r
<br /> a Investigate the local stratigraphy of the site.
<br /> 3.1.1 §0jj BorIngsi{
<br /> Soil borings will be drilled to enable installa,:ion of observb-tion
<br /> wells. Truck mounted hcllow-stem auger drilling equipment :rill be used,
