Dr. Elaine McGoff:

I can give an answer to Senator Murphy. It depends - that is a great answer - on what one is looking at. If one is looking at nitrate, it is in the south and the south east. If one is looking at phosphate, it is much more spread and is on heavy soil. Sediment is a really big problem. We are also seeing problems because of forestry with our water quality and we seeing problems with what is called hydromorphology where one is dredging and straightening rivers. If you look at the EPA maps, a lot of those problems are spread all over the place. As nitrate is quite isolated in the south and south east, the pristine water bodies tend to be up in the uplands where there is not much agriculture. Forestry is the main pressure on the pristine water bodies, so if you have non-afforested uplands, that is usually where the best of the best is left.
