Figure 7.1 Average groundwater use in Virginia by category 2003 – 2007 (2008_AWRR). Manufacturing includes operations such as paper mills, food processors, drug companies, furniture, and concrete companies; Public water supply includes municipal and private water purveyors; Agriculture includes operations such as commodity farms, fish farms and hatcheries; Irrigation withdrawals are used to promote growth in crops such as tobacco, corn, soybeans, turf grass, and ornamental nursery products; Commercial operations include golf courses, local and federal installations, hotels, and laundromats; Mining includes operations such as sand, rock, and coal companies
Streams are sensitive to salts, sediment, shade, temperature and flow
Terrestrial and aquatic life may be affected by discharges and runoff. With annual average rainfall of 43 inches for the state and 45 inches in Danville, water will be an issue.

Issues- my own reflections • $, not public service or benefit • Greatest unknowns • Risks, not assessment • Virginia is neither ready nor capable
