So your brain says it's safe. Got it. I feel so much better now.
To be honest, I'm not exactly hoarding bottled water (which normally comes from a municipal water supply anyways) and activated charcoal. Hell, I'm not even using a Britta filter - it's probably not enough to be concerned about for humans. The studies simply indicate pharmaceuticals are ending up in the water supply. I can't control how my body metabolizes any medications I take, but I can control where my old medications end up.
That being said, humans aren't the only ones drinking the water, there's plenty of other species to be concerned about. The topic definitely needs more study.
As for FUD - the studies don't have any of that. They simply state "We analyzed these places, we found these drugs." Environmental groups may run with it and spew their own FUD, but they're going to do that anyways. Anyhow, the whole point of science is to study things and report findings. Long term studies with large samples can be used to find correlations and even theorize at causation. A study isn't invalid simply because the findings don't align with your beliefs. A study is invalid because its sample is flawed, it's methods are flawed, or its analysis is flawed.
Anyhow, like I said before, I'm still throwing my old pills in the trash instead of dumping them down the toilet. My trash can is right next to the toilet anyways, so it's not any great inconvenience. When my wife's aunt passed away, it wasn't difficult to take her meds to a pharmacy in town for disposal either. God knows what they did with it, but at least I know we didn't add them to the water table...
