DECEMBER 2017 RESEARCH UPDATE

Welcome to December, the holiday season and a turn toward winter, frozen ground, snow and ice.  But for Dr. Sally Brown, at work in the Northwest U.S., clouds and rain set the tone of the season. So her thoughts in the December Research Updates turn to the performance of "green infrastructure," those increasingly common bioswales and detention ponds amidst our parking lots, commercial developments and "complete streets."  She is particularly interested in how these devices are deployed, not so much for moderating the hydrology of stormwater discharge to streams, but for their ability to alter the quality of water, especially reducing toxicity of stormwater to aquatic life.  She faces an establishment that, at the starting gate, is biased against biosolids-based components of bioswale soil mixtures, because of presumptions that biosolids-borne metals and nutrients work at cross purposes to high water quality.  That may not be so, particularly for those biosolids with iron and aluminum compounds that can adsorb and chelate contaminants. So, here is Dr. Brown's take on the new research into this area of specialty soil mixes for stormwater management.  For a copy of this opinion-piece blurb and her abstracts of cited literature, go to our website, for which you will need to log-in. And, as always, if you care to receive the original articles, just send a note to wtoffey@mabiosolids.org
