OCSD were currently taking to reduce NDMA in WF-21 water and the proposed GWRS
project. The solution included a three-pronged effort to prevent precursor compounds that
form NDMA from entering OCSD, optimizing both agencies’ treatment processes to remove
NDMA and evaluating a DHS-approved UV treatment process for the proposed GWRS project.
OCWD effectively communicated how concentrations in drinking water wells is reduced by
dilution and, that based on data, Orange County’s groundwater was safe. Changes were
made to the WF-21 process and OCSD’s wastewater flows to reduce NDMA to 20 ppt or less
and UV with hydrogen peroxide was ultimately implemented at the GWRS to combat NDMA
concentrations that occur when chlorine is used in the potable reuse process. This information
was actively shared with local retail agencies, city councils, service organizations, regulatory
agencies, and media. This outreach effort resulted in balanced stories in key newspapers and
online publications and no public or political outrage; only one misguided quote from a person
that had been turned down to do a joint study earlier that year.
A few months later, in July of 2000, there was concern that the outreach program needed to be
increased because the boards of directors of both the District and OCSD would be taking a
vote within six months as to whether to proceed with the final design and move forward with
the project. It is also interesting to note that during this time, the LADWP East Valley Water
Project was drawing political and local opposition, which added to the need to increase GWRS
outreach efforts and make sure that the project succeeded.
The one thing that had been learned through the focus groups was that the more information
the public received about the GWRS and the need to ensure a safe, reliable water supply, the
stronger the support from the public. At this point in time, staff recommended holding two
additional public workshops, cable television and radio advertising, additional media relations,
an expert spokesperson and direct mail to targeted audiences. The proposed budget for this
work was between $525,000 - $600,000. The Committee ultimately decided to conduct
additional public opinion research (polling), two to four public workshops, direct mail outreach
and media relations with a budget of $110,000 for this additional effort. The Committee did not
see the need for a major media effort using cable television or radio advertising.
The polling was done by the same firm that was hired three years earlier and some of the
major findings from the polling were:
1. When asked about Orange County water supplies and anticipated population growth,
78% said that Orange County does not have enough water unless new supplies are
found, which was a 19% increase over the prior survey
2. When asked if they were aware of a new water project in Orange County that would
reclaim and purify wastewater, 53% were aware, which was a 28% increase
3. When asked if they favor the project, 36% were in favor, which was a 17% increase
4. When given the statement that “The trouble with trying to repurify sewer water is that
even our best technology can’t get out all the impurities and germs”, 60% agreed, which
was an 11% decrease.
What this information indicated was that the outreach campaign was working in that more
people were aware of OCWD’s messaging and the project, but also that more work had to be
