EIR Addendum

An addendum was prepared  for 2018 PWS EIR. It describes the inclusion of an adjacent property next to the Chanticleer site and several refinements to the water treatment processes and facility layouts (referred to as Modified Project) and presents the updated environmental analysis performed on the Modified Project relative to the environmental impacts of the approved Project that were disclosed in the certified 2018 PWS EIR.  The Board of Directors approved the adoption of the addendum on November 17, 2020.

Potential Injection Aquifer Geochemical Characterization

Project Memorandum on Nanoparticle Concerns (February 2016) (PDF). 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.


CEC Removal Through Advanced Treatment

At the Board's October 20, 2015 meeting, Andy Salveson from Carollo Engineers, presented the following:

  • 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
  • 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
