Appendix B - Cost Matrix for Watercraft and/or Grab Samples The following matrix summarizes the sample collection costs, lab analysis for basic ambient parameters, data review, upload to Seminole Water Atlas, and biannual data uploaded to STORET (via Atlas). The Total Costs need to be multiplied by the sampling frequency (12 for monthly, 4 for quarterly, etc.) to determine Total Annual Costs. This cost matrix is based on samples collected using a watercraft or a combination of watercraft and grab samples. Due to the logistical efforts for watercraft accessed samples, the maximum number of samples that can be collected daily is six (6) sites. No. of Sample Sites Sample Collection Cost Lab Analysis Cost* QA/QC and Upload of Data to Water Atlas Total Costs "multiply by sampling frequency 1 $200.00 $179.50 $40.00 $419.50 2 $265.00 $359.00 $40.00 $664.00 3 $330.00 $538.50 $40.00 $908.50 4 $395.00 $718.00 $40.00 $1153.00 5 $460.00 $897.50 $40.00 $1397.50 6 $525.00 $1077.00 $40.00 $1642.00 7 $725.00 $1256.50 $80.00 $2061.50 8 $790.00 $1436.00 $80.00 $2306.00 9 $855.00 $1615.50 $80.00 $2550.50 10 $920.00 $1795.00 $80.00 $2795.00 11 $985.00 $1974.50 $80.00 $3039.50 12 $1050.00 $2154.00 $80.00 $3284.00 *Lab Analysis Costs based on the following group of parameters that Seminole County currently collects for its ambient monitoring program. Harbor Branch Environmental Laboratory Analysis Costs are based on 2009 Loxahatchee contract, and are subject to revision upon contract expiration. Parameter Lab Cost Parameter Lab Cost Ammonia-NH3 15.00 Ortho -Phosphate 10.00 Nitrite 10.00 Chlorophyll A corrected 45.00 Nitrate 10.00 Color 9.00 TKN 15.00 Fecal Coliform 13.00 BOD5 17.50 Total Suspended Solids 10.00 Total Phosphorus 15.00 Alkalinity 10.00 Total lab costs/event 179.50 Field Sampling includes the following field parameters (at no additional cost): • Water temperature • pH • Conductivity • Total Dissolved solids • Dissolved Oxygen • Turbidity • Flow The following table lists additional lab analysis costs, if requested by cities. (These parameters will not increase the collection costs per sample, only the analytical lab costs.)
