SCOPE OF WORK (continued) The annual report will summarize and interpret the following information (for all four quarters): o All groundwater monitoring data, including laboratory and field data for the sampling periods o Statistical results and/or any statistical trends, including findings of any statistical increases for the year including time series plots of concentrations o A summary of concentrations above the maximum contaminant levels of Chapter 173-200 WAC, Water Quality Standards for Groundwaters of the State of Washington o A summary of the leachate results compared to groundwater samples o A summary of the landfill gas conditions o Static water level readings for each monitoring well for each sampling event o Potentiometric surface elevation maps depicting flow direction for each sampling event o Groundwater flow velocity calculations for each sampling event and a discussion of any trends or changes during the year o Geochemical evaluation, including cation -anion balancing and trilinear and/or stiff diagraming for each sampling event noting any changes or trends in water chemistry for each well during the year One hard copy of the final report will be submitted to Kittitas County, Ecology, and the Health Department. BUDGET We estimate that the scope of services described herein will require a budget of $293,109.64. A breakdown of these costs is presented on the attached spreadsheet. Parametrix agrees not to exceed the above budget without the County's authorization. However, if during the work, a level of effort beyond the scope of our work appears necessary, Parametrix will contact the County immediately to discuss any necessary modifications to the scope of services and/or budget estimate. The budget presented in this proposal reflects an estimate based on our current understanding of the project requirements for a scope of work developed from information provided. Parametrix reserves the right to transfer hours and budget dollars between tasks to satisfy project requirements. The budget also reflects estimated direct costs to the project. Parametrix may also transfer funds allocated for direct costs to professional/technical hours, or vice versa, to satisfy project requirements.
