The Draft TMDL Implementation Plan for Moores Creek, Lodge Creek, Meadow Creek, and Schenks Branch is available for public comment through October 22, 2012. The draft plan is available on the DEQ website.
DEQ and local water quality partners met on September 20, 2012, at 6:00 p.m., to discuss the condition of local streams and recommendations to improve them. This meeting featured a panel discussion of local efforts to clean-up local streams. Click here for more information.
Based on routine water quality monitoring, four streams in Charlottesville and Albemarle County have been added to the list of waterways in Virginia that do not meet water quality standards.
VADEQ reports this list to the USEPA every other year in the 305(b)/303(d) Water Quality Assessment Integrated Reports as required by the federal Clean Water Act of 1972. Moores Creek and its tributary, Lodge Creek, were originally listed as impaired on Virginia's in 2008 and 2006, respectively, due to violations of the general aquatic life standard.
Meadow Creek and its tributary, Schenks Branch, were originally listed as impaired in the same reports in 2006 and 2008, respectively, also due to violations of the general aquatic life standard. A Total Maximum Daily Load must be prepared for streams that do not meet water quality standard and are listed as impaired.
Why don't these streams support a healthy aquatic community? After reviewing various types of data and examining possible stressors in the aquatic habitat, VADEQ and its Technical Advisory Committee identified the primary stressor on the aquatic community in each stream to be sediment.
Sediment is soil that has been washed off the land during rain storms and soil that is scoured from the stream banks by fast moving water. Development has changed the way rainwater moves over land and through stream channels. Impervious surfaces have a negative impact on water quality because these surfaces, like pavement, rooftops and sidewalks, do not allow precipitation to slowly infiltrate into the soil.
