Arlington tap water usually tastes either like dirt or chlorine.
We have needed to purchase bottled water ever since the water pipe cleansing this past spring (2017).
It is inconvenient to routinely transport (heavy to carry) water to the home. It is also an additional recurring household expense that I would rather not pay. Brita filters do not help that much; other brands of water purifiers also have limitations, such as turning the water-taste sour after about a month.
I believe that Arlington residents would be willing to pay a little more to get better quality drinking water from the tap.
Efforts to keep streams clean from pet-waste (such as from dog parks near streams), trash, and other pollutants should also be actively pursued.
