sources of groundwater contamination within the delineated areas and the risks <br />associated with those potential sources, The primary risk for contamination to the <br />public ddnkin9 water is from hazardous materials spilled onto the 9round or allowed to <br />enter the storm drains or surface water. <br /> <br />Springfield has delineated the drinking water protection areas around the public water <br />supply wells operated by the Springfield Utility Board and Rainbow Water Distdct in <br />addition to the surface water protection area for the water treatment plant on the <br />middle fork of the Willamette River operated by the Springfield Utility Board. The <br />delineations have been certified by the Department of Human Services Ddnkin9 Water <br />Program, Certification Number 002. As part of the risk evaluation done in developing <br />the Drinking Water Protection Plan, aquifer sensitivity analysis were preformed that <br />identified hazardous materials as a high risk with dense nomaqueous phase liquids <br />(DNAPL's) posing the highest risk for aquifer contamination. DNAPL's are a separate <br />subset of hazardous materials (most are chlorinated solvents) that are heavier than <br />water, sink in the aquifer, and are very hard to clean up. <br /> <br />Springfield has adopted Article 17, which identifies an overlay zone and protective <br />measures addressing hazardous material use and storage for new businesses inside <br />the zones of contribution in the Drinking Water Protection Areas. All new or <br />expanding businesses inside the overlay zone are required to 9o through the plan <br />review and approval process to assure compliance with the ordinance and protection <br />of the drinking water resource. Inspection and follow up are provided by Springfield <br />Utility Board in cooperation with the City of Springfield. <br /> <br /> 14.5 Fixed Site Hazardous N~aterials Locations in Lane County and the <br /> EugenelSpringfie~d N~etro Area <br /> <br />The Oregon Office of State Fire Marshal maintains a comprehensive listing of <br />hazardous substances locations in Oregon4, Key data for Lane County and the <br />Eugene/Springfield Metro Area are shown below in Table 14.2, <br /> <br /> Table 14.2 <br /> Summary of Hazardous Substance information System (HSIS) Data <br /> <br /> Sites with: <br /> Tota~ Reportable 112(r)~ 313 (TRI)2 EHS3 <br /> County Reports Quantities Chemicals Chemicals Chemicals <br /> Lane 4474 1773 1048 450 157 <br /> Eugene 2489 939 559 281 77 <br /> Springfield 735 292 180 97 38 <br /> Metro Area 3224 1231 739 378 115 <br /> <br /> ~ Chemicals reportable under Section 112(r) <br /> 2 Chemicals reportable under Section 313,Toxics Release Inventory <br /> 3 Extremely hazardous substances <br /> <br /> For Lane County, the HSIS database has hazardous materials reports for 4474 <br /> companies and other entities such as cities and universities that have hazardous <br /> <br /> Public Rewew Draft: October 12, 2004 14-7 <br /> <br /> <br />
