Here's the DPU's 2005 assessment of the drinking water in the Richmond area:

Interestingly to note is that the amount of water being pumped has increased since 1999 (based on a brochure Dr. Forsyth has given me) and that Richmond's water supply is 100% up to US water standards. The DPU's website is; http://www.ci.richmond.va.us/DPU/

CBP (Chesapeake Bay Program)

The CBP provides a wealth of knowledge about watersheds. A watershed is essentially a group of rivers, streams, etc. which feed into a larger body of water. My study observes the James River Watershed (near the bottom of the map) which eventually feeds into the Chesapeake Bay. As you can see the large extent of the watershed means large regions as well as local communities have a responsibility to preserve this natural feature.

Lets zoom into the James....

Richmond is in the Middle, so lets get closer

Zoom into Richmond..

Just to give you an idea of how this map relates to my current location, The University of Richmond is on the border of Henrico County and Richmond (upper portion of this map). Besides these maps, the CBP also provides valuable data regarding the James River Watershed.
Here are two charts, the one on the left is in reference to toxic releases from 1989-1999 while the right discusses the mode of pollutants affecting the James River Watershed in 1999. The actual amount of pollutants is near 3,000,000 lbs.
