1、惠來縣城區(qū)及周邊飲用水水質(zhì)監(jiān)測評價研究報告《梅州城區(qū)及周邊飲用水水質(zhì)監(jiān)測評價》課題組2009年11月19日9二、惠來城區(qū)自來水及周邊飲用水源水質(zhì)初步監(jiān)測結(jié)果水是生命的搖籃,飲用水水質(zhì)狀況是關(guān)系人類健康、生存與發(fā)展在諸因素最為重要的要素!惠來城區(qū)自來水及周邊飲用水水源水質(zhì)狀況已引起社會廣泛關(guān)注。這也是當今人們對生態(tài)環(huán)境保護的關(guān)切與期望的真實表現(xiàn)。課題組自《梅州城區(qū)自來水及周邊飲用水水源水質(zhì)監(jiān)測與評價》立項以來(2003.10~2004.11),對嘉應(yīng)學院自產(chǎn)自來水、象山水、梅州城區(qū)(嘉應(yīng)學院南生活區(qū))自
