water table protection Water table is inherently susceptible to contamination from landuse activities. Remediation is very expensive and often impractical. Prevention of contamination is therefore critical in effective groundwater management (地下水极易受到土地利用活动的污染。整治地下水是非常昂贵的，而且往往是不切实际的。因此防止污染在地下水的有效管理中很关键。); groundwater protection Precautionary actions, procedures or installations undertaken to prevent or reduce harm to the environmental integrity of fresh water found beneath the earth's surface, usually in aquifers, which supply wells and springs (为避免和减少对地下水体环境整体性的损害，所采取的预防措施、程序或安装的装置，而这些地下水体通常位于含水层，是井水和泉水的来源。) |
