Detection of gravitational wave sources consisting of massive binary black holes (BBH), in particular, is still a challenge due to contamination from noise transients called glitches. I will discuss our efforts to distinguish BBH from specific kinds of glitches. Gravitational lensing of gravitational waves is expected to be detected in the near future. I will present an improved statistic which will help identify candidate lensed GW events. The stellar population located within lensing galaxies are thought to produce distortions in the gravitational wave signals referred to as microlensing. I will also discuss how severe such microlensing effects are going to be and how they may affect detection of strongly lensed GW events.
