Pozad\u00ed<\/h2>\n\n

Dne 5. srpna 2015 do\u0161lo v \u0159ece Animas v Coloradu ke katastrofick\u00e9mu \u00faniku chemik\u00e1li\u00ed. Miliony galon\u016f odpadn\u00edch vod z vy\u0161et\u0159ov\u00e1n\u00ed Agentury pro ochranu \u017eivotn\u00edho prost\u0159ed\u00ed (EPA) n\u00e1hodn\u011b vytekly do \u0159eky a obarvily jej\u00ed vody na zlov\u011bstnou oran\u017eov\u011b \u017elutou barvu.<\/p>\n\n

Rozsah a \u00fa\u010dinky \u00faniku<\/h2>\n\n

Zpo\u010d\u00e1tku odhadli pracovn\u00edci EPA rozsah \u00faniku na jeden milion galon\u016f. Pozd\u011bji v\u0161ak tento odhad revidovali na v\u00edce ne\u017e t\u0159i miliony galon\u016f. \u00danik m\u011bl v\u00fdznamn\u00fd dopad na ekosyst\u00e9m \u0159eky, kontaminoval jej\u00ed vodu a ovlivnil divokou zv\u011b\u0159.<\/p>\n\n

\u00danik tak\u00e9 vytvo\u0159il mrak odpadn\u00edch vod, kter\u00fd se t\u00e1hl p\u0159es 160 kilometr\u016f. Dos\u00e1hl hranice Nov\u00e9ho Mexika a srazil se s \u0159ekou San Juan, co\u017e potenci\u00e1ln\u011b ovlivnilo tak\u00e9 jezero Powell a \u0159eku Colorado.<\/p>\n\n

\u010cistic\u00ed pr\u00e1ce<\/h2>\n\n

Prob\u00edhaj\u00ed \u010distic\u00ed pr\u00e1ce s c\u00edlem omezit \u00fanik a zm\u00edrnit jeho dopady.

Jarn\u00ed odtok by mohl potenci\u00e1ln\u011b uvolnit potopen\u00fd kov a kal, kter\u00fd byl vyplaven na b\u0159ehy \u0159eky, by mohl p\u0159edstavovat zbytkov\u00fd probl\u00e9m.<\/p>\n\n

Dopad na divokou zv\u011b\u0159 a \u010dlov\u011bka<\/h2>\n\n

Durango tak\u00e9 uzav\u0159elo toky \u0159eky do m\u011bstsk\u00fdch n\u00e1dr\u017e\u00ed.<\/p>\n\n
