[en] We report the detection of H₂O maser emission from three new galactic regions; a point 0'.9 NE of T Tauri, and toward the H ii regions G29.9--0.0 and G0.55--0.85. The T Tauri water source is not coincident with any known optical object; comparison of the H₂O and CO observations of this region suggests the presence of an embedded protostellar region in the molecular cloud. We have monitored these sources and those in S140-IR and Mon R2 for time variations and have found that all sources except T Tauri are time-variable on the scale of a month. A model for the varying component of Mon R2 is proposd
