Why STORET for Region 10? Bunker Hill Mining and Metallurgical Superfund Site
Site Overview • Listed as a Superfund site in 1983 • The Coeur d'Alene Basin and downgradient Spokane River are severely impacted by over 100 years of mining activities. • Significant measurable risks exist to: • Humans (e.g., children with blood lead levels above national CDC standards) – some of the highest human blood lead levels measured here • The environment (e.g., major tributaries devoid of aquatic life, yearly die-off of migrating waterfowl). • Collaborative process involving 2 states, 2 tribes, USFWS, USGS, BLM, communities and citizens • One of the largest Superfund sites and very controversial with substantial community interest Tundra Swans
Data Issues – Data Problems Over 5000 historical station locations and over 600,000 analyses to manage Sampling will continue for the next 30+ years - sampling by numerous entities EPA Contractor Issues – periodic change in Superfund contractors associated with significant data management costs for data migration and maintenance Data access and tools for stakeholders/community to view data are limited
STORET Provides the Answers through Collaboration • Over 5000 historical station locations and over 600,000 analyses to manage • Historical data was migrated into STORET Summer 2004 – (URS, Regions 8 and 10, Gold Systems, HQ) • Sampling will continue for the next 30+ years - sampling by numerous entities • Web Simm interface is under development, data submitters will provide an electronic data deliverable that is acceptable for STORET upload (URS, Regions 8 and 10, Gold Systems, HQ) • EPA Contractor Issues – periodic change in Superfund contractors associated with significant data management costs for data migration and maintenance. • STORET is the new data repository for the historical Superfund site data
Data access and tools for stakeholders/community to view data are limited • Creation of a National STORET GIS Layer for use in mapping (Region10, HQ) • HTTP://WWW.STORET.ORG (URS and Region 10) • Bunker Hill Mining and Metallurgical Complex Internet Mapping Application • Mapping STORET results – a mapping application that displays analytical results (Regions 8, 10, HQ) • Reporting and graphing tools (URS and Region 10) • Region 8 STORET Internet Mapping Application (Region10)
Creation of a National STORET GIS Layer 2 Simple Suggestions for Accurate Mapping of STORET Stations • Supply Latitude and Longitude - Measure the location of stations using GPS. • Over 1100 stations were removed from the STORET Mapping Layer • because “0,0” were supplied for the Lat, Long fields. • Datum - Providing “unknown” or “other” as entry to the horizontal_datum field causes accuracy problems when mapping station locations so choose a • horizontal datum for your data.
Analytic Results on a Map or in a Report 3 Simple Suggestions for data input • Supply Units of Measure • Supply Analytical Method • Don’t Use Special Characters in Text Fields - Any embedded quotes, &#%+ or other special characters – they create problems when trying to process data
