水文地质研究通常涉及在没有车辆进入的情况下在现场获取水质样本。这种情况通常需要使用采样泵。蒙大拿大学的研究人员一直在使用由可充电变速钻头驱动的手持式蠕动泵。这款蒙大拿钻泵 (MDP) 非常便携，制造成本低廉，价格约为 225 至 295 美元（美国）。在过去的二十年中，该泵已被用于对地表水和地下水进行采样和过滤（视情况而定），以分析一般无机和有机化学、稳定和放射性同位素、病原体和微量药物，并开发小直径井和样本吸入渗漏仪。 MDP 为研究人员和教育工作者提供了一种经济的工具，可以在教室、实验室和现场环境中抽水。
Hydrogeologic research often involves obtaining water quality samples in field settings without vehicle access. Such conditions often require the use of a sampling pump. Researchers at The University of Montana have been using a handheld peristaltic pump powered by a rechargeable variable‐speed drill. This Montana Drill Pump (MDP) is highly portable and can be inexpensively built for about $225 to $295 (US). Over the last two decades, the pump has been used to sample and filter (as appropriate) surface water and ground water for analyses of general inorganic and organic chemistry, stable and radioactive isotopes, pathogens, and trace pharmaceuticals and to develop small‐diameter wells and sample suction lysimeters. The MDP provides researchers and educators with an economical tool to pump water in classrooms, laboratories, and field settings.
