A recently granted patent (Publication Number: US11828686B1) discloses a liquid sampling apparatus designed to collect and store liquid samples from a body of liquid efficiently. The apparatus includes a frame supporting at least one bailer, with features such as a base with holders for the bailer, an upper portion for securing the bailer, elongate members connecting the base and upper portion, and a weight that can move between retracted and downwardly extended positions. This weight helps maintain the apparatus and bailer in a vertical orientation during sample collection, supported by a telescopic second member associated with the first member.

Furthermore, the patent describes a method for sampling surface water using the apparatus, involving lowering it into the water body with at least one groundwater sampling bailer attached. The method includes collecting water samples while keeping the apparatus and bailer in a vertical position, facilitated by the movable weight. The apparatus's design allows for efficient sample collection while ensuring stability and accuracy in the sampling process, making it a valuable tool for various applications requiring liquid sampling from bodies of water.
