    • The packing-seal is shown in use in a borehole as a level-isolating seal for a groundwater sampler. The packing-seal shown includes an expandable annulus of Dowell (TM) water-expandable material. Surrounding that is a pressure-sleeve of rubber. A sheet of woven Kevlar (TM) is wrapped circumferentially around the sleeve and the Dowell annulus, such that the ends of the Kevlar sheet overlap. Outside the Kevlar is an outer rubber sleeve. Upon expansion of the packing seal to fill the borehole, the Kevlar sheet unwraps to allow the Dowell to expand without restraint. Once the packing seal has filled the borehole, the Kevlar sheet is prevented from unwrapping further. If the borehole contains a fissure the Kevlar provides a rigid bridge over the fissure, and prevents the packing-seal from ballooning out into the fissure.

    • The disclosed sampler comprises a reservoir formed as a stainless steel tube of narrow diameter. Two copper tubes are attached to the reservoir, one each end, and the copper tubes may be crimped so as to seal the sample within the reservoir. The sample (of water) is allowed into the reservoir through a check-valve which is opened and closed by controlling the pressure--from the surface --inside the sampler. The disclosed sampler is sealed into the borehole by means of an inflatable collar, which is also under the control of a surface-manipulated pressure. Samples transported and stored in the sampler are presented for analysis complete with contained gases and uncontaminated.
    • 所公开的采样器包括形成为窄直径的不锈钢管的储存器。 两个铜管连接到储存器,一个端部,并且铜管可以被压接以便将样品密封在储存器内。 通过控制采样器外表面的压力打开和关闭的止回阀,使样品(水)进入储存器。 所公开的采样器通过可充气的套环将其密封在钻孔中,该套环也处于表面操纵压力的控制之下。 样品运送和储存在采样器中的样品用于分析,含有气体和未污染物。

    • Water draining from a septic tank contains ammonium, which traditionally is oxidized to nitrate in an aerobic soakaway. When the effluent enters the groundwater, the resulting nitrate concentration can be troublesome. A body of organic carbon, e.g. wood chppings, is provided, and the nitrate-laden effluent is passed through the carbon. The carbon is placed in the ground so as to be anaerobic: for example, the carbon may be placed below the water table; or the carbon may be mixed into a layer of fine silt, which is maintained in a state of tension-saturation by the effluent. Under anaerobic conditions, the nitrate is reduced by micro-biological action. The carbon is located such that the effluent naturally flows through the carbon, no pumps etc being required. The carbon may be located directly below the soakaway, or the carbon may be in a trench positioned to the side if the groundwater has a lateral component of flow.
    • 从化粪池排出的水含有铵,这在传统的氧气渗透中被氧化成硝酸盐。 当污水进入地下水时,所产生的硝酸盐浓度可能很麻烦。 有机碳体,例如 提供木屑,含硝酸盐的流出物通过碳。 将碳放置在地下以便是无氧的:例如,碳可以放置在水位下方; 或者碳可以混合成一层细小的淤泥,其保持在流出物的张力饱和状态。 在厌氧条件下,硝酸盐通过微生物作用降低。 碳的位置使得废水自然地流过碳,不需要泵等。 碳可以位于浸泡的正下方,或者如果地下水具有侧向流动分量,则碳可以位于侧面定位的沟槽中。
