- Project Memorandum on Nanoparticle Concerns (February 2016)
This memorandum was drafted in response to a specific request from the Soquel Creek Water District (SqCWD) regarding nanoparticles. The SqCWD wanted to know the latest information on nanoparticles as they pertain to potable water reuse projects. Nanoparticles are not regulated for potable water reuse projects (or potable water projects, for that matter). In conversations with the State of California Division of Drinking Water (DDW) in January 2016, the DDW defined their position on nanoparticles, which is that existing regulations are protective of public health and that there is no intent to regulate nanoparticles. With that said, DDW will continue to evaluate the issue.
2015
- Framework for Direct Potable Reuse
- CEC Removal Through Advanced Treatment.
At the Board's October 20, 2015 meeting, Andy Salveson from Carollo Engineers, presented a technical memo that included a comprehensive literature review; data from several existing facilities currently using AWP; comparisons between recycled water, surface water, and our own District groundwater in terms of CEC levels; and detailed testimonials regarding his own personal experiences with looking for endocrine disrupters, pathogens, viruses, and other potential contaminants in recycled water during his 19 years working in the field.
- Technical Memo "CEC Removal Through Advanced Treatment" (by Carollo Engineers, dated October 2015). References and the literature review for the TM are available in hard copy at the District office.
- PowerPoint Presentation from 10/20/2015 meeting
- Technical Memorandum No. 2- CEC Removal through Advanced Treatment with Addendum. As part of the Carollo Feasibility Study, a follow up Technical Memorandum was prepared to investigate CECs which included sampling of the SC WWTF secondary effluent.
