In my previous post, I indicated that HPS' belated measures to manage the copper problem were sufficient. Nope. December 2017: I identified 3 taps in the science lab kitchen area with very high (>4 ppm, in one case ~40 ppm) copper levels. I was surprised -- these should have been tested and passed by HPS (in fact, I watched the technician sample these taps in Mar 2017). January: I tested taps that had been judged safe by the city, and found at least 9 working sinks with levels over the standard. 3 additional sinks with filters were, of course, over the standard. Currently (1/14/18): I have shared results with Administration. Staff and parents have also been informed of recent preliminary test results. Many sinks have been turned off, and for others there is a flushing protocol being put into place, as well as signage. Once again, Administration says that a final testing and remediation plan will be shared with families, staff, and students.
I have refrained from emotional language in this blog. But: the installation of useless filters is flat-out incompetent, and negligent. And not especially surprising.
