How is subsurface injection typically accomplished?

Subsurface injection is a method employed in aquatic pest control that effectively distributes chemicals below the surface of the water. This technique is carried out using short hoses positioned at 2 ft intervals, which allows for precise placement of the treatment material in the water column where it can reach targeted organisms more effectively.

Short hoses facilitate better control over the injection process. By maintaining a 2 ft interval, this method also ensures even distribution and reduces the risk of creating large concentrations of chemicals, which could be harmful and less efficient. The specific placement of the hoses allows for an adequate coverage area while addressing the specific depths where target species are most likely to be found.

While other methods, such as drilling holes in the water surface or using long hoses at 4 ft intervals, could theoretically transport substances, they do not align with the typical practices recognized for subsurface injection that prioritize targeted and efficient application. Aerial applications with drones, although useful for some pest management strategies, do not provide the controlled depth and targeted distribution that subsurface injection specifically requires.
