Focus: Groundwater monitoring is a key to protecting the environment. Several issues the work group may consider include requiring submittal of quarterly monitoring reports, requiring electronic submission of quarterly monitoring data through Ecology's Environmental Information Management System, determining whether analyses for metals must be conducted for dissolved or total constituents, and clarifying what happens if monitoring indicates that corrective action steps need to be taken. 

Update: The workgroup responsible for rewriting the WAC 173-350-500 section has completed its work. Ecology has prepared draft language to be shared with stakeholders in the spring of 2016. Please send questions to w2rrulemaking@ecy.wa.gov
