Disclosed herein is an apparatus for facilitating sampling water of water bodies, in accordance with some embodiments. Further, the apparatus comprises a primary housing, a secondary housing, a movement assembly, a sensor, a storage device, and a power source. Further, the secondary housing is submerged in a water body based on disposing of the primary housing. Further, the secondary housing receives a water sample from a depth of the water body in a secondary interior cavity through an opening of the secondary housing based on submerging of the secondary housing in the water body in the depth. Further, the movement assembly transitions the secondary housing between a retracted position and an extended position for the submerging. Further, the sensor generates sensor data based on detecting a characteristic of the water sample. Further, the storage device stores the sensor data. Further, the power source powers the sensor, and the storage device.
