James River water quality study
On June 21, 2006, DEQ biologists took water samples from the James River along a 200-mile stretch from Lynchburg to Hopewell. The monitoring sweep was related to an investigation of foam observed in the river. The results from each of the 29 monitoring stations are listed below. Click on any of the (

Additional monitoring data related to the foam investigation and a description of the substances measured are also available.
