- 1998 General Assembly Legislation Related to WaterVirginia Water Resources Research Center; Manfre, Joseph (Virginia Water Resources Research Center, 1998)The Virginia General Assembly held its regular session from January 14 to March 17, then reconvened April 22-23 to respond to the governor’s vetoes. A special session on April 23-24 passed the budget along with car-tax and school-construction-grant legislation. During the regular session, 2152 bills were considered (939 passing, 651 failing, and 562 carried over until 1999), along with 730 joint resolutions (580 passing, 115 failing, and 36 carried over). Among all this legislative action were 97 water-related bills and joint resolutions.1 (Hereafter, we will use “bills” to include both bills and joint resolutions.) To identify bills related to water, we used the Legislative Information System’s subject index, looking first under two categories: “Waters of the State, Ports and Harbors” and “Water and Sewer Systems.” Of the 97 bills listed below, 73 were in one of these two categories. We then found 24 other pertinent bills under these categories: Conservation; Fisheries and Habitat of Tidal Waters; and Game, Inland Fisheries and Boating.

- Adsorption of organic compounds onto solids from aqueous solutionsWightman, James P.; Dole, Leslie R.; Jones, J.; King, Clarence A. (Water Resources Research Center, Virginia Polytechnic Institute and State University, 1971)The use of solids to remove pollutants is not novel in the sense that solids are used presently for this purpose. For example, the use of charcoal is well known, and the use of alumina in phosphate removal has been investigated. The removal of phenol from aqueous solutions on a variety of solids has been studied in this work. The rationale for this study is as follows. An aqueous solution containing a pollutant (phenol) is a three component system consisting of a solute (phenol) and solvent (water) in contact with a solid. The question arises, what about the removal of the pollutant by the solid? In many instances the kinds of solids that have been used are those which not only compete for the pollutant, but also compete for water. Thus, not only is the interaction between the pollutant and the solid important, but also the Interaction between the water and the sol id. In many systems, for example herbicides, insecticides, and phenol, there is a Iimited solute concentration, which means that there is a basic incompatability in the system to start with. Then as this solution is put in contact with a solid surface, the amount of pollutant and the amount of water removed become relevant. If the solid has an attraction for water in addition to the pollutant, water may be removed and block parts of the solid which could be effective in removing the pollutant. This study has been concerned with the adsorption of phenol from aqueous solutions on several solids chosen to alter the competition of water and phenol for the surface of the solid.

- Agricultural land use : effects on the chemical quality of runoffSmolen, M. D.; Shanholtz, Vernon O. (Virginia Water Resources Research Center, Virginia Polytechnic Institute and State University, 1980)This research is the first phase of the Blackstone Environmental Quality Program, a study to distinguish the water quality effects of agricultural practices. Th is research focused on changes in runoff quaIity when land is put under cultivation. The data will be used in later phases of the program to evaluate chemical transport models. The three study watersheds, located in Virginia's southern Piedmont, had not been under cultivation for 30 years. During the research, two of the watersheds were put into agricultural production while the third was left uncultivated and used as a control. A grab sampling program was maintained on two watersheds for the full five-year period of study. Continuous streamflow gaging was maintained for the last four years. During the final three years, sampling and flow gaging were also maintained on a third watershed. For those three years, grab sampling was supplemented by automatic samplers for stormflow sample collection. Samples were analyzed .for nitrate, ammonium, and total Kjeldahl nitrogen, orthophosphate and total phosphorus, bicarbonate alkalinity, pH, and specific conductance. Clear differences in streamflow characteristics were noted between the treated and the control watersheds. More surface runoff was observed in the treated watersheds than in the control, suggesting that increased surface runoff may have resulted from the cropping activity. All three watersheds exceeded the phosphorus criterion proposed by the Environmental Protection Agency, and a two-to-threefold increase in total phosphorus concentration was attributed to agricultural land use without employment of conservation practices. A twofold increase in total nitrogen concentration also was noted. Soluble inorganic nitrogen was present at a low concentration in the control watershed, but accounted for 20-30 percent of all nitrogen exported from the treated watersheds. The presence of nitrate nitrogen in the agricultural watersheds was the characteristic most attributable to agricultural activity. The research showed that serious enrichment problems could occur in Piedmont lakes or impoundments if the predominant land use of a watershed were agricultural cropping and if conservation practices were not employed.
- Agricultural use of sewage sludge : a literature reviewKelley, W. D.; Martens, David C.; Reneau, Raymond B.; Simpson, Thomas W. (Virginia Water Resources Research Center, Virginia Polytechnic Institute and State University, 1984-12)Stricter regulations on discharge of sewage into waters, higher costs of alternate disposal procedures, and higher prices of chemical fertilizers have increased interest in the use of sewage sludge in crop production. This review addresses the benefits and risks of agricultural use of sewage sludge. Topics evaluated in this study are the biological, chemical, and physical aspects of sewage sludge relating to trace elements, pathogens, nitrogen, and phosphorus and also the economic aspects of land application of sewage sludge. For each topic, additional research needs are identified.
