Lower York River Dissolved Oxygen Study, Robert A. Jordan
Lower York River Dissolved Oxygen Study, Robert A. Jordan
Reports
Past studies of the lowerr York River have shown that dissolved oxygen (D .O.) concentrations decline in the summer months, occasionally falling one mg/ 1 near the bottom in deep water (Brehmer,1970; Jordan,1973) . Due to this apparently natural phenomenon the Virginia water quality standards for D.O. in estuaries (4.0 mg/1 allowable minimum, 5 .0 mg/1 minimum daily average, U.S.. E.P.A,1971), are not met during this period . Therefore additional waste-water discharges into the lower York River will not initiate violation of the standards, but may exacerbate the existing situation by extending the area and the time period affected by …
