Task_2: Data consolidation and presentation, <br />EnviroSolutions will reduce all field and laboratory analytical data collected during groundwater <br />sampling activities. We will incorporate the results into the databases EnviroSolutions <br />developed for the City of South Bend municipal source groundwater monitoring program. The <br />databases allow for trend analysis and comparison to state and federal screening levels. <br />EnviroSolutions will describe the field operations and present the results in a brief report for the <br />City of South Bend. Reports will be submitted in May and November of 2019. <br />COST <br />The estimated costs for labor and materials to complete the requested tasks based on our current <br />understanding is $12,725.00. If costs change based on actual site conditions, EnviroSolutions <br />will seek approval from the City of South Bend prior to proceeding. These costs do not include <br />laboratory analytical services. <br />Opt0nal Task 3: South Well Field Moiii taring Wcli_Ejevation Survey <br />EnviroSolutions will survey the elevations of the top of casing and ground surface at all <br />monitoring wells sampled in the South Well Field relative to an area bench mark. The elevation <br />data, combined with the depth to groundwater measurements collected during sampling, can be <br />used to demonstrate the groundwater surface contours in the South Well Field area. <br />Groundwater surface contours drawn on the aerial view of the South Well Field illustrate the <br />groundwater flow direction. In turn, the groundwater flow direction can provide assistance in <br />predicting the movement of dissolved chemicals in area groundwater. <br />The cost for EnviroSolutions to conduct the elevation survey, reduce the survey data, and <br />provide the information to the City of South Bend is $460.00. If the City of South Bend chooses <br />for EnviroSolutions to perform the survey task, this one-time cost would be added to the total <br />cost. <br />TIMELINE <br />Services will be scheduled immediately upon receipt of a completed proposal acceptance form. <br />After receipt of the proposal acceptance form, EnviroSolutions will complete the requested work <br />under the schedule mandated by City of South Bend. As stated above, the intended schedule for <br />groundwater sampling activities to occur in April and October of 2019. Summary reports will be <br />submitted to the City of South Bend in May and November of 2019. <br />Thank you for the opportunity to provide services to the City of South Bend.
