| Description | The City of West Richland (City) is developing an Aquifer Storage and Recovery (ASR) facility at existing City Well No. 10 in conjunction with the Washington State Department of Ecology’s (Ecology) Office of Columbia River (OCR). During the course of delivering Phase 2a of the project (aquifer testing, baseline sampling, and permit application), Ecology requested that the City conduct additional (not included in the original project implementation plan or Grant Agreement) groundwater sampling to develop a formal determination of background water quality in accordance with Ecology publication No. 17-10-035: Guidance for Aquifer Storage and Recovery AKART Analysis and Overriding Consideration of the Public Interest Demonstration (November 2017). This guidance document describes an evaluation of background that is based on eight samples. Because the baseline characterization sample already collected as part of Phase 2a can be used to support this analysis, an additional seven samples are planned as described in this QAPP addendum. The original Phase 2a Quality Assurance Project Plan (QAPP) describes aquifer testing, water quality sampling, geochemical compatibility analysis, and development of information needed to conduct an all known, available and reasonable methods of prevention, control and treatment (AKART) analysis. This Phase 2a QAPP Addendum describes only the additional sampling, analytical program, and schedule associated with collecting seven groundwater samples to be used in establishing background groundwater quality at Well No. 10. Field methods and procedures and QA/QC procedures remain unchanged from the original QAPP except where specifically noted below in this addendum. |
