Sampling of the Middle and South River May Be Key to Accurate Nutrient Pollution Data

[caption id="attachment_1140" align="alignleft" width="300"] Middle RIver, Augusta County[/caption] Augusta County is voluntarily considering a sampling program to determine the amount of pollutants that are leaving the county via its two primary waterways – the Middle and South rivers.  Now that the EPA has provided the “green light” of acceptance, it’s back in the county’s court to decide whether to proceed with the sampling. The decision to move forward has been hinging on whether or not grants could be obtained to meet operational costs as well as uncertainty about whether the EPA would accept the data. EPA has now deemed that the proposed monitoring "is consistent with other monitoring being done as part of the Chesapeake Bay River monitoring program." Supervisors will revisit the sampling idea when they meet in late July. For more details, click to read the news article:

Low Impact Design Examples on Display at Science Museum of Richmond

[caption id="attachment_886" align="alignleft" width="300"] Bioretention Area[/caption] As design professionals, many of us feel uneasy about the lack of data documenting stormwater BMPs performance. The data that is available shows a wide range of treatment efficiencies for the same types of BMPs and lacks completeness in documenting how design parameters, maintenance, and other conditions can affect performance. So it’s great to see that the Science Museum of Virginia, in cooperation with Virginia Tech and the City of Richmond, is pursuing several projects to expand the base of stormwater BMP knowledge. The Science Museum has installed the following: • two tree box filters • a bioretention area • a cistern • an area of permeable concrete • vegetated green roof [caption id="attachment_891" align="alignleft" width="300"] Tree Box Filter[/caption] These systems are equipped with instrumentation, including flow weirs and samplers to collect data. The projects are currently collecting data. If you are in the Richmond area, please visit the Science Museum and see...
