The extra analysis resulted in sampling another lake site and also for more detailed <br />sampling at 1 m increments at the 5401 site. Our normal sampling of Lake Owasso is done at the 5401 site. <br />The extra analysis is charged for but we did not charge for our normal sampling regimen. I did not charge <br />for extra dissolved oxygen, temperature, pH, and specific conductance testing. The extra analyses costs for <br />the two sites, 5401 and 5403, are summarized in the tables below: <br />Analysis 2008 Count Cost/$ Subtotal/$ <br />Barr-Ow Ow5401 2008 Scott Sobiech <br />Field time 4 $35.00 $140.00 <br />TP-MG/L 38 $4.80 $182.40 <br />SRP-MG/L 38 $7.70 $292.60 <br />TDP-MG/L 78 $8.25 $643.50 <br /> Subtotal $1,258.50 <br />Analysis 2008 Count Cost/$ Subtotal/$ <br />Barr-Ow Ow5403 2008 Scott Sobiech <br />Field time 4 $35.00 $140.00 <br />TP-MG/L 51 $4.80 $244.80 <br />SRP-MG/L 51 $7.70 $392.70 <br />TDP-MG/L 51 $8.25 $420.75 <br />CCHLA-PviG~ivl3 8 $11.45 $9 i .60 <br /> Subtotal $1,289.85 <br /> Tota15401 $1,258.50 <br /> Tota15403 $1,289.95 <br /> Total X2,548.45 <br />Our Accounting Division will prepare a billing invoice for $2,548.75 and send it to you for review and <br />payment. <br />Sincerely, <br />Lewis Soukup <br />Lab Manager <br />Lewis.soukup~co.ramsey.mn.us <br />651-266-7161 <br />cc: Tony Lutgen <br />Terry Noonan <br />
