APRIL 2018 RESEARCH UPDATE

Dear Biosolids Friends,

Dr. Brown swallows hard and takes on an overview of the environmental fingerprint of society's use of pharmaceutical and personal care products (PPCPs).  She reminds us that, by the sheer numbers and spread of humanity and through our sophisticated instrumentation, when we look for traces of PPCPs in our water enviornment, we will find traces of PPCPs. The traces may be in the parts per trillion concentrations, but they are there, released from feedlots, septic tank and sewage treatment plants. What does this mean? The reports Dr. Brown reviews do not offer insight into that question, but she does try to point out that the land application of biosolids is not the meaningful source, nor are our WWRFs to blame. If you have people, you have PPCPs.  Continue with the blurb below and, if you can, try to wrap your head around 7 billion people and a part per trillion, For a copy of this opinion-piece blurb and the articles Dr. Brown cites, 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.
