Preliminary Assessment of Participating Utilities: The preliminary assessment included examination of water quality, water production, and site details for each of the participating utilities to assess non-treatment options, treatment technologies, and associated costs to address nitrate and co-contaminants (e.g., 1,2,3-trichloropropane (1,2,3-TCP) and perchlorate). Demonstration locations were selected from nitrate-impacted candidate sites; Rio Bravo Greeley School Water System, Lindsay Strathmore Irrigation District (LSID) – Tonyville, and Woodville Public Utility District were included in this assessment.

Affordability Workshops: Workshop presentations are included on the Publications page.

• The 1st Affordability Workshop was held at UC Davis on Friday, April 13, 2018
• The 2nd Affordability Workshop was held at UC Davis on Wednesday, October 17, 2018
• The 3rd Affordability Workshop was held at UC Davis on Thursday, March 28, 2019

Affordability Assessment: This assessment discusses affordability considerations; examines the preliminary costs of treatment in the context of what is considered affordable for the communities served by the participating utilities; and explores affordability metrics, potential funding sources, and policy options. Part 1 of this report can be found on the Publications page.

Shared Service Administration: This project has already produced several significant achievements that will lower the cost of nitrate treatment for utilities in the San Joaquin Valley:  

• Collaborative Funding. Our research project is funded by Proposition 50, Chapter 6b for three community systems simultaneously. This innovative approach to providing safe and wholesome water to a cluster of economically disadvantaged systems has enabled project efficiency.  
• Shared Engineering Services. Evaluation and selection of the best available treatment technology, coordination with State Waterboards Division of Drinking Water, development of equipment procurement documents, site improvement design services and Operations and Maintenance Plans were completed for all three communities by the same engineering team, streamlining the current practice.
• Bulk Consumables Delivery. The Project Team sourced a Southern California salt supplier to extend their delivery business to the Central Valley; bulk deliveries reduce costs, traffic and waste.
• Equipment Procurement Documents. Template have been developed for bidding that can be adapted for other communities and are available at no cost.
• Operations Plan Documents. Template documents have been developed with State Waterboards Division of Drinking Water that can be adapted for future community needs.
