drinking water

We were warned in advance not to drink too much of the tap water - heavy metals contained in it, not bacteria.  We bought  bottled water upon our arrival and learned right away that we were looking for "niegasowana" (no gas).  The sparkling water has never been my favorite, although it appears to be preferred by many here.  After bringing in 2 liter bottles every time we left the apartment (and making Adam shlep two 6 liter bottles home on the bus one day, we decided to look into Brita water filters.  David did his research and discovered that the Brita Maxtra filter passed quality tests in Lublin and several hundred other cities, so that was our next purchase at the store.
