    • The invention is directed to a portable carrying device that includes a housing, an elongated flexible strap extendable from the housing, and at least one rigid support arm attached to the housing and configured for supporting an article to be carried. The portable carrying device can include a coupler disposed on a first end of the elongated flexible strap and a mating structure disposed on a portion of the housing for releasably securing the coupler. The rigid support arm can be movable from a first position in which the rigid support arm is compactly stored relative to the housing, to a second position in which the rigid support arm is at least partially extended away from the housing. The housing can have at least one recess for receiving the rigid support arm and the rigid support arm can have a shape corresponding to the recess.

    • A remediation method for decontamination of soil and groundwater that puts maximum remediation stress on the entire area and volume of contamination. This results in site restoration in days and weeks. The target contaminants are organic compounds such as hydrocarbon constituents associated with diesel fuel, gasoline, kerosene, solvents and creosote. Cleanup concentrations to non-detectable levels can be achieved when properly implemented. Positive pressure is used to push an uncontaminated gas throughout the entire contaminated area/volume. When contacting the contaminated area, volume and media, this gas becomes a carrier gas, stripping the contaminants and carrying them to ground level where they can be collected and treated or dissipated to the atmosphere. The method incorporates air entry points (vertical, horizontal, or directional) installed to a depth below the contamination, combined with a predetermined air entry point spacing (depth/spacing ratio). Use of an operating duty cycle enhances contaminant yield from the groundwater, the soil matrix below the groundwater table, and the soil above the groundwater table. Horizontal migration of contaminants during the process is prevented by the use of gas entry points around a boundary perimeter of the zone being purged. One or two days' use of the method produces the same results as one year of other remediation methods, such as "pump and treat". Transfer or removal rates of 40% to 50% per day of the existing contaminants are normal. No (vacuum) extraction wells are necessary to make this in-situ method work. Biodegradation is not a factor. Progress is measured by the amount of contaminants remaining. Site rehabilitation to regulatory standards, measured in micrograms per liter or parts per billion, can be achieved within weeks.
    • 对土壤和地下水去污的补救方法,对污染的整个面积和体积施加最大的补救压力。 这导致了几天和几周的现场恢复。 目标污染物是有机化合物,例如与柴油燃料,汽油,煤油,溶剂和杂酚油相关的烃成分。 当正确实施时,可以实现不可检测水平的清除浓度。 使用正压将整个污染区域/体积的未污染气体推出。 当接触污染区域,体积和介质时,这种气体将成为载气,剥离污染物并将其运送到地面,在那里可以收集和处理或散发到大气中。 该方法将空气入口点(垂直,水平或方向)安装到污染物深度以下,并与预定的空气入口点间距(深度/间隔比)相结合。 使用工作周期提高了地下水,地下水位下面的土壤基质和地下水位以上的土壤的污染物产量。 通过在被清除的区域的边界周边周围使用气体入口点来防止污染物在过程中的水平迁移。 一两天的使用方法产生与其他补救方法(如“泵和治疗”)相同的结果。 每天40%至50%的现有污染物的转移或去除率是正常的。 没有(真空)提取井是必要的,以使这种原位方法工作。 生物降解不是一个因素。 进度由剩余污染物的量测量。 按照每公升或十亿分之几计算的监管标准的现场修复可以在数周内完成。
