What weird definition of "found water" are they using that makes the finder Chandrayaan 1? Apollo 14 detected lunar water vapor in 1971. Lunar samples obtained both by the Apollo program and the Soviet Luna 24 probe in 1976 contained water.
The water in the Apollo samples have been dismissed by scientists as being contamination from Earth. Besides, the water discovery being referred to here is in orders of magnitude more quantity, at the lunar poles. The reason the discovery of lunar water is credited to Chandrayaan 1 is because it confirmed it beyond any doubt via two instruments.
