140万加仑牲畜废水流入堪萨斯河道，州卫生部发布水道警报
据《首府日报》（Capital-Journal）报道，堪萨斯州卫生与环境部（KDHE）10月7日发布水道警报：约140万加仑牲畜废水排入麦金太尔溪（McIntyre Creek），该溪流向堪萨斯河汇入。
据报道，KDHE建议居民避免接触受影响河段及下游水域——牲畜废水可能携带超标细菌（包括大肠杆菌）与消耗氧气、危害水生生物的营养物。这批废水来自托皮卡东北肖尼县（Shawnee County）的一处牲畜养殖场，官员表示污染带正顺流向堪萨斯河移动。
KDHE称正在多个点位监测水质，并与涉事养殖场合作阻止废水继续外排、防止重演。此类溪流警报通常在检测显示细菌水平恢复安全范围后才会解除，视流量与天气可能需要数日。
牲畜废水外排在堪萨斯州是老问题：大型养牛场与养猪场多临水而建。环保组织一直敦促州政府加强对废水氧化塘与土地施用的监管，农业团体则表示多数经营者遵守规则、事故罕见。
KDHE表示将随水质检测结果更新向公众通报，并敦促发现水体变色或死鱼者报告。
堪萨斯州畜牧业是该州经济支柱，此次事件再次引发关于养殖场选址与水道保护距离的讨论。
KDHE Issues Warning After 1.4 Million Gallons of Livestock Wastewater Enter Kansas Waterways
TOPEKA, Kan. — The Kansas Department of Health and Environment issued a public warning Oct. 7 after roughly 1.4 million gallons of livestock wastewater was discharged into McIntyre Creek, which flows toward the Kansas River, the Capital-Journal reported.
KDHE advised residents to avoid contact with water in the affected stretch of McIntyre Creek and downstream waters, warning that livestock wastewater can carry elevated levels of bacteria, including E. coli, as well as nutrients that deplete oxygen and harm aquatic life. The discharge originated from a livestock operation in Shawnee County, northeast of Topeka, and officials said the plume was moving downstream toward the Kansas River.
The agency said it was monitoring water quality at multiple points and working with the facility to stop the discharge and prevent recurrence. KDHE stream advisories typically remain in effect until testing shows bacteria levels have returned to safe ranges, a process that can take days depending on flow and weather.
Livestock waste discharges have been a recurring issue in Kansas, where large cattle feedlots and hog operations sit near waterways. Environmental groups have pressed the state for stronger oversight of waste lagoons and land application, while agriculture groups say most operators follow the rules and that accidents are rare.
KDHE said it would update the public as water testing results come in and urged anyone who sees discolored water or dead fish to report it.
Kansas's livestock industry is a pillar of the state economy, and the incident has renewed debate over setback distances between feedlots and waterways.
