INTRODUCED April 27 ' 1998 By Al Gurule Councilperson APPROV D: Pr6kident of the Council ATTEST: FWA! 01 W. R's 0 �!� It - City • Council Agenda Title: A RESOLUTION APPROVING AN AGREEMENT Agenda Item # BETWEEN ARCADIS, GERAGHTY & MILLER, INC., FOR ENVIRONMENTAL SERVICES ASSOCIATED WITH HYDRO GEOLOGY 4 Department: WASTEWATER DEPARTMENT Date: APRIL 27, 1998 ISSUE Should the City of Pueblo award a contract to ARCADIS Geraghty & Miller, Inc., for professional services associated with Hydrogeology. RECOMMENDATION Approval of the Resolution. BACKGROUND The Colorado Water Quality Control Division is proposing revisions to the Classifications and Numeric Standards for the Arkansas River Basin regarding selenium. The Basin Standards will ultimately be incorporated into the calculations for establishing the City's wastewater treatment plant discharge limits. Since the selenium is naturally occurring in the Pueblo area, the burden is on the City to provide the data to the State related to the selenium source and concentration. ARCADIS Geraghty & Miller, Inc., will review and collect environmental data related to the local geology which will be submitted to the Colorado Department of Public Health and Environment, along with other data prepared by City staff. FINANCIAL IMPACT The proposed fee for professional services stipulated in the agreement is $59,200 plus time and materials for any work done beyond the original scope of work. Funds will come from the Wastewater - Professional Services account number 014- 0400 - 435 -000- 030 -0020.

ATTEST: CITY OF PUEBLO, A MUNICIPAL CORPORATION -7- City CtiTi6 President of 16e City/Council ARCADIS Geraghty & Miller, Inc. By T72c�S Name: Title: �Ge �v/�°� P F:\ FILES\ CITY\ WWTP\ WQCC \SELENIUM\1998\PROFSRVS.WPD _g ARCAUIS GERAGHTY& MILLER EXHIBIT A Scope of Work CITY OF PUEBLO DEPARTMENT OF WASTEWATER SELENIUM COMPLIANCE SUPPORT Work completed previously by Geraghty & Miller in February 1995 characterized the relationship between the Pierre Shale and selenium concentrations in soils, groundwater, and surface water in an area northwest of the University of Southern Colorado (University Park neighborhood). This areas is just one of two primary areas known to contribute the majority of the selenium loading to the City of Pueblo Wastewater Treatment Plan (WWTP). The second and most significant area contributing to selenium loading is an area north of the Colorado State Hospital in the vicinity of Fairmount Park (Fairmount Park neighborhood). The February 1995 work provided a conceptual model of the hydrogeologic relationships between groundwater, surface water, and infiltration and inflow (I /I) into the sanitary sewer system. However, collection of sufficient data to support this model was not within the scope of that work. The goals of this scope of work include the following: Validate the conceptual model that groundwater intercepted by the WWTP via I/1 would ultimately discharge to the Arkansas River prior to and irrespective of the urbanization of the City of Pueblo. Characterize the relationship between the Pierre Shale and selenium concentrations in soils, groundwater, and surface water in the Fairmount Park Neighborhood. Characterize the hydrogeologic groundwater flow system in the immediate vicinities of the University Park and Fairmount Park neighborhoods. Provide a final report that incorporates previous work and develop simple, clear, and concise presentation graphics to illustrate selenium transport processes. Task 1 - Characterization Within the City The task will include a geochemical investigation of the area immediately north of the Colorado State Hospital to identify sources of selenium, establish the relationship between high selenium concentrations believed to be present in the Pierre shale, and selenium concentrations in groundwater, soil, and surface water.I This work will ' Estimated costs assume that all groundwater and surface water chemical analyses will be performed by the City of Pueblo Department of Wastewater. Page: 1/5 \ \gm_d entech \data \tech rest \pro posa 1 \560060.Oco\sm.doc ARCADES GERAGHTY& MILLER include a scope similar to that performed by Geraghty & Miller on behalf of the City of Pueblo in late 1994. However, some minor modifications to this scope have been made to minimize duplication of work with Task 2 and control costs. This work will include installation of five groundwater monitoring wells, and collection of soil, groundwater, and surface water samples in order to develop a conceptual of selenium transport in the Fairmount Park neighborhood area. Because a significant amount of insight was gained through the previous investigation, fewer sampling locations are required for this task than were installed in late 1994. The final deliverable of this task will be revision of the February 1995 Field Investigation Results, Selenium Source Characterization Report (1995 Selenium Report) prepared by Geraghty & Miller to include the new information detailed in Task 5. Estimated Cost Task 2 - Hydrogeological Evaluation $14,600 This task will include two major components: research of available information (Task 2a) and a groundwater transport evaluation (Task 2b). The availability of relevant and focused hydrogeologic information for either the University Park or Fairmount Park neighborhoods may reduce the scope of Task 2b and lower the overall cost of this task. Task 2a - Research of Available Hydrogeological Information This goal of this task will be to identify an obtain all available information that may aid in interpreting the localized hydrogeology of the University Park or Fairmount Park neighborhoods or the Fountain Creek, Wildhorse Creek, and Arkansas River basins in the Pueblo area. It is anticipated that the primary source of this information will be the United States Geological Survey (USGS). Geraghty & Miller will work cooperatively with the USGS to complete this work. It is believed that sufficient data are available from the USGS to eliminate the need to perform a field investigation to establish the hydrological relationship between Fountain Creek and the shallow alluvial aquifer in the Pueblo Area in general. However, it is unlikely that this information will be available specifically for the reaches of Fountain Creek and Wildhorse Creek within the specific study areas of interest. The research effort will be limited to contacting the USGS and other parties referred by the USGS. The collected background information will be used to focus Task 2b. If sufficient information is available, Task 2b will be reduced in scope and cost. Estimated Cost $ 3,100 Page: 215 \ \g m_dentech \data \tech resc \proposal \560060.Oco\sow. doc ARCADIS GERAGHTY& MILLER Task 2b - Groundwater Transport Evaluation The goal of this task is to develop and support a conceptual model with data, of groundwater transport within the shallow aquifers in the University Park and Fairmount Park neighborhoods demonstrating that groundwater intercepted by sump pumps operated by homeowners and via inflow into the sanitary sewer would indirectly or directly flow to the Arkansas River. The hydraulic characteristics of the aquifers will be identified based on a limited hydrogeological investigation in each of these areas. Five permanent groundwater monitoring wells will be installed in the University Park neighborhood. The groundwater monitoring wells installed in the Fairmount Park neighborhood as part of Task 1 will be located and constructed to meet the requirements of this task as well. No additional costs will be incurred to install additional wells. In addition, permanent gauging stations will be installed in Wildhorse and Fountain Creeks. The locations of each of the monitoring wells and gaging stations will be surveyed for both elevation and lateral location. Water surface elevations will be measured in each of the wells and at the surface water gaging stations a minimum of two times to ascertain the seasonal variability of the hydrogeological conditions. The potentiometric surface of the groundwater will then be mapped over the Fairmount Park and University Park neighborhoods. The average hydraulic conductivity will be estimated at one location in each neighborhood via simple drawdown testing of the planned permanent groundwater monitoring wells. The information gathered in this investigation will be evaluated to determine the relationships between the shallow aquifers, nearby surface water bodies ( Wildhorse and Fountain Creeks and the Arkansas River), and the effects of I/I into the sanitary sewer system. The hydrogeological conditions of the local aquifers prior to urbanization of the City of Pueblo will also be evaluated and calculated. The final deliverable of this task will be revision of the 1995 Selenium Report to include the new information. Estimated Cost Task 3 - Selenium Loading Evaluation $ 29,200 The goal of this task is to estimate the loading rate of selenium into the City of Pueblo wastewater treatment system resulting from inflow and infiltration (I/1) in the University Park and Fairmount Park neighborhoods. This task will use and build upon the recently completed 1/I study performed by the City of Pueblo Department of Wastewater. This evaluation requires information developed in Tasks 1 and 2 plus information gathered as part of the I/1 study, including the average selenium concentration in groundwater in the Fairmount Park and University Park areas, knowledge of the approximate number of households with basement sump pumps 2 The term model refer to a conceptual model of the interrelationships between the groundwater and surface water systems and not a computer -based model.

If sufficient historic groundwater elevation data are available for the areas of interest, the water table elevation and selenium loading to the W WTP could be correlated. The final deliverable of this task will be revision of the 1995 Selenium Report to include the new information. Estimated Cost Task 4 - Final Report Preparation $ 4,300 A single final report will be completed to present the results of work completed under the tasks described above and the previous work completed by Geraghty & Miller. Each of the tasks described above includes some report preparation budget. However, it is expected that the final work product will be a complex report that requires additional editing to incorporate comments from the City of Pueblo and to create a single, high quality document for presentation to the Colorado Department of Public Health and the Environment. Estimated Cost $ 2,500 Task 5 - Illustrative Animation A computerized illustrative animation will be prepared to graphically demonstrate the transport of selenium through the groundwater and the interaction of the groundwater system with surface water and the Pueblo sanitary sewer system. The animation will consist of a simple, clear, and concise conceptual cross section, demonstrating dissolution of selenium from the Pierre Shale into shallow groundwater and the generalized transport of groundwater containing elevated selenium concentrations under both urbanized (current) and pre- urbanized conditions. The graphics will demonstrate discharge of groundwater to surface water prior to urbanization and capture of a portion of the groundwater by the sanitary sewer system after urbanization. Estimated Cost $ 5,500 s Costs assume the listed information items will be available prior to initiation of this task. Page: 4/5 \ \gm_dentech\ data \tech resc\proposa 1360060.0coXsow.doc ARCADES GERAGHTY& MILLER SCHEDULE Geraghty & Miller will begin work on Task 1 immediately upon notice to proceed by the City of Pueblo and once a contract is executed. It is recommended that field work associated with tasks 1 and 2b be prioritized and completed concurrently in order to collect water surface elevation data prior to the spring runoff. Additional water surface elevation data will be collected again in April or May to determine the seasonal variability of these data. All of the work will be completed prior to July 15, 1998, including completion of the final report and development of the illustrative animation.
