The PVC booms are part of a portable water filtration system to collect environmental DNA (eDNA) samples. At the end of the booms are a filters connected to tubing that runs back to a 12v peristaltic pump (brand is Geotech) and I set this up, filter a pair of water samples, partially break down the system and move to the next. Collection of eDNA is to survey for the presence of rare aquatic species and the canoe and portable pump system allowing covering a few miles of remote access water in a day. Not often (not often enough) are Land Cruiser capabilities needed to reach some remote access point on a stream, but sometimes the access is down a rocky road, muddy track or just a trail through the woods.
