佛罗里达州的地质水文学允许在某些地区对经过处理的废水进行深井注入，前提是要注意保护用于公共供水的上覆含水层。本文讨论了在处理井的施工、运行和最终废弃过程中必须采取的预防措施，以确保对注入的废物进行控制。施工期间必须采取以下预防措施:研究该地区的地质水文，以预测具有高矿化自流水的高产区；在井场周围建造一块不透水、有路缘石的混凝土板，以便进行钻探和测试； 多层套管设计，周围有厚环形空间，允许对水质和压力不同的区域进行适当的固井和隔离；分期建设；导向孔和铰孔的垂直对准和方向控制，以确保钻孔的钻孔段完全有效地胶结；建立地下水监测系统，检查上覆淡水含水层的质量；以及通过使用封隔器测试或其他等效方法确认接收含水层上的承压层的有效性。在操作过程中，必须采取预防措施，控制注入流量和井口压力，并监测将接收区与新鲜或不新鲜区域分开的限制层的有效性- 矿化的上覆含水层。废弃处置井时，需要从底部到表面对套管进行完全密封。包括4个参考文献、表格和图表。

The geohydrology of Florida allows deep-well injection of treated wastewater in some areas, if care is taken to assure protection of overlying aquifers used for public water supplies. This article discusses precautions that must be taken during construction, operation, and ultimate abandonment of the disposal wells to assure containment of injected wastes. The following precautions must be taken during construction: research on the geohydrology of the area to anticipate highly productive zones with highly mineralized artesian waters; construction of an impermeable, curbed concrete slab around the well site to allow drilling and testing; multiple-casing design with thick surrounding annular spaces to allow proper cementing and isolation of zones with differing water qualities and pressures; staged construction; vertical alignment and directional control of both pilot and ream holes to make sure that drilled sections of the holes are completely and effectively cemented; establishment of a groundwater monitoring system to check the quality of the overlying freshwater aquifer; and confirmation of the effectiveness of the confined layers overlying the receiving aquifer through the use of packer testing or other equivalent methods. During operation, precautions must be taken to control the flow rate of the injection and wellhead pressure and to monitor the effectiveness of the confining layers separating the receiving zones from the fresh or less-mineralized overlying waterbearing strata. When a disposal well is abandoned, complete sealing of the casing from the bottom to the surface is required. Includes 4 references, tables, figure.
