Abstract: Means are disclosed for introducing a biological poison to water being removed from a lake or stream for presentation to an automatically operating water quality monitoring system. The poison introducing means is operative at only periodic intervals; and, when operating to introduce poison, a sampling device of the monitoring system is disabled to preserve its accuracy. The monitoring system is otherwise permitted to operate routinely during the time the poison is present in the system. The poison is admixed to the water promptly as the water is introduced to the monitoring system, with the result that the biological poison will cleanse the entire monitoring system by killing biological slime otherwise adhering to the exposed surfaces within the system. The biological poison also maintains sensor sensitivity within the monitoring system. The biological poison further suppresses biological activity in the water being monitored, thus preserving sample values that would otherwise have changed as the water being sampled advanced to remotely located monitoring equipment.

Abstract translation: 公开了将生物毒素引入从湖泊或溪流中排出的水以呈现给自动运行的水质监测系统的方法。 毒物引入装置只能周期性地进行; 并且当操作引入毒药时，监控系统的取样装置被禁用以保持其准确性。 否则允许监测系统在系统中存在毒物时常规操作。 当水被引入监测系统时，毒素会及时混入水中，结果是生物毒物会通过杀死生物泥而清除整个监测系统，否则会粘附在系统中的暴露表面。 生物毒物也可以在监测系统内保持传感器灵敏度。 生物毒物进一步抑制被监测的水中的生物活性，从而保留随着取样的水被提前到远程监测设备而变化的样品值。
