Tribar Release Surface Water Chromium Sampling Results

This data is used in the Tribar Release Sampling Results interactive web app (item details). The Michigan departments of Health and Human Services (MDHHS) and Environment, Great Lakes, and Energy (EGLE) and local officials are working together to protect residents in Monroe, Oakland, Livingston, Wayne, and Washtenaw counties following a release of hexavalent chromium to the Wixom Sewage Treatment Facility from Tribar Manufacturing in Wixom. The sewer feeds the Wixom wastewater treatment plant, which discharges to the Huron River system. Sites shown on the map represent targeted locations. Latitude/longitude coordinates may vary slightly with each visit due to on-site sampling logistics and GPS accuracy. This data was last updated 9/14/22 and shows sampling through 9/8/22. This data shows surface water results for Hexavalent Chromium and Total Chromium.

Hexavalent chromium is a known carcinogen that can cause a number of adverse health effects through ingestion, skin contact or inhalation. Residents with questions about hexavalent chromium, potential health effects or exposures can call the MI Toxic Hotline at 800-648-6942, 8 a.m. to 5 p.m., Monday through Friday. Extended hotline hours will be offered this weekend, Saturday, Aug. 6 and Sunday, Aug. 7, 8 a.m. to 5 p.m. EGLE makes every attempt to ensure data accuracy but cannot guarantee the completeness or accuracy of the information contained within these datasets.

本数据集用于Tribar排放采样结果交互式Web应用（项目详情页）。密歇根州卫生与人类服务部（Michigan Departments of Health and Human Services, MDHHS）、环境、大湖与能源部（Environment, Great Lakes, and Energy, EGLE）以及地方官员正携手开展工作，在威克姆市Tribar Manufacturing公司向当地污水处理厂排放六价铬（Hexavalent Chromium）后，保护门罗县、奥克兰县、利文斯顿县、韦恩县与沃什特瑙县的居民。该污水管网接入威克姆污水处理厂，该厂最终将污水排入休伦河（Huron River）水系。地图上标注的点位均为本次采样的目标点位。由于现场采样的后勤安排与GPS精度限制，每次采样的经纬度坐标可能存在小幅偏移。本数据集最后更新于2022年9月14日，涵盖截至2022年9月8日的全部采样数据。本数据集包含六价铬与总铬（Total Chromium）的地表水检测结果。
