Certain forms of stream restoration may have the potential to mobilize chemical cocktails of metals, and long-term monitoring is important to identifying these changes in water quality following restoration and construction activities. These peaks reached values comparable to peaks observed during winter road salting events at approximate values of 12.9, 0.146, 64.6, 73.8, 8.01, 0.526, and 0.415 mg/L, respectively. Peaks in magnesium, strontium, sodium, calcium, potassium, manganese, and barium were observed after the restoration occurred, and were 44, 55, 65, 95, 100, 361, and 407 percent larger, respectively, than values for a nearby control reference stream. Regenerative stormwater conveyance (RSC) is a retrofit on ‘zero’ order streams that incorporates elements of Read More. Regenerative SPSCs are open-channel conveyance structures that convert, through surface pools and a subsurface sand seepage filter, surface storm flow to shallow groundwater flow. Pre-restoration water chemistry data has been collected routinely over the past three years and was compared to post-restoration sampling to identify benefits and trade-offs of RSC restoration. However, standing pools that raise water temperatures and decrease dissolved oxygen could potentially release metals that have sorbed onto the streambed as an unintended consequence.

Campus Creek in College Park, Maryland was restored during the summer of 2019 using regenerative stormwater conveyance (RSC): an open-channel approach utilizing a series of step pools and sand channels to slow and filter streamwater and retain nutrients such as nitrogen, phosphorus, and heavy metals before they are transported further downstream. known as regenerative stormwater conveyance. No objection to the final plans for the installation of a regenerative stormwater conveyance in Bingham Run on the west side of Rock Creek Park south of. Stream restoration projects may have unintended consequences on water quality that are not well understood due to a lack of monitoring before and after restoration.
