Great and interesting project - I'm really impressed by your team finding new ways to use the new tech of fiber optics. What are the limitations of this type of detection? I ask because I understand there to be a huge demand for innovative pipeline assessment and detection technologies, not only related to water quality but to the physical pipeline quality itself - a demand that's only growing with aging infrastructure. Do you have any thoughts on this, or is the fiber optic technology only suited for quality concerns like turbidity? Would love to learn more. Thanks, and great work!
