工作任務(wù)和要求 主要任務(wù)（一）建立全國(guó)加油站/儲(chǔ)油庫(kù)清單信息，遴選需重點(diǎn)調(diào)查評(píng)估的加油站/ 儲(chǔ)油庫(kù)；（二）開(kāi)展重點(diǎn)調(diào)查的加油站/儲(chǔ)油庫(kù)地下水基礎(chǔ)環(huán)境狀況調(diào)查與污染現(xiàn)狀評(píng)價(jià)； （三）完成加油站/儲(chǔ)油庫(kù)地下水調(diào)查評(píng)估數(shù)據(jù)庫(kù)建設(shè)及成果圖集編制工作。如，前些年北京市安家樓加油站和六里屯加油站均發(fā)生過(guò)嚴(yán)重的漏油事故，曾一度迫使附近的自來(lái)水廠停止運(yùn)行。2022
