Environmental health experts at Environmental Health Coalition filed this comment letter today on the most recent monitoring reports on the Chatham contamination. EHC Chatham Comment Letter Feb 26 2015<\/a>.
\nThere is important information about 1,4-Dioxane and it speaks eloquently to several issues we are facing locally.  We are very grateful to EHC to their enduring commitment to community health.<\/p>\n

Here are some excerpts<\/p>\n

Regarding whether Natural Attenuation is occurring:<\/u><\/p>\n

\n“The latest monitoring
\nresults do not provide evidence that natural attenuation is occurring.  Increased levels of TCE occur at sampling
\nsites up and down Felicita Creek, including both the northern and southern
\nportions. Not only are the levels not diminishing, this pattern of  monitoring results does not support the Hargis
\ncontention that levels in the more northerly part of the creek will diminish
\nfirst, followed by levels in the down gradient portions of the creek and plume.
\nIn fact, these results show neither a short term nor a long term pattern of
\nattenuation in TCE levels. Levels in FC-4, one of the wells in the northern
\npart of Felicita Park, show an increasing trend over the 20-year period from
\n1994 through mid-2014, as charted in Figure 7 of the Hargis Technical
\nMemorandum of January 16, 2015. <\/o:p><\/i><\/span><\/div>\n
\n<\/div>\n
\nAnother well in the
\nnorthern area of the Park, FC11\/11A, shows an increase since the previous round
\nof monitoring in April 2014. Levels of TCE in MW-58 appear to be exactly the
\nsame in the most recent results as they were 15 years ago, in 2000, also shown
\nin Figure 7.”<\/o:p><\/i><\/span><\/div>\n
\n<\/div>\n
\nRegarding the length of time of the natural attenuation:<\/u><\/div>\n
\n<\/div>\n

<\/p>\n

\n“Not only do these results
\nfail to support the PRP consultant\u2019s theory, the PRP group fails to provide any
\nestimates of how long they expect this natural attenuation process to take. How
\nlong are they expecting Felicita Creek and groundwater to remain contaminated?
\nHow many more years are they asking Escondido families to be patient while
\nupwelling of contaminants continues into their neighborhood park and their
\ngroundwater wells? A generation of children has grown up since the Chatham
\nplume began its migration, and we\u2019re still being told that attenuation will
\neventually occur. It is past time for DTSC to demand that the PRPs take additional
\naction to remediate the plume, as well as to treat all wells that have
\nmeasurable levels of chlorinated hydrocarbons or 1,4-dioxane.”<\/i><\/o:p><\/span><\/div>\n

\nRegarding what the MCL does and doesn’t mean and a preference for the PHGs:<\/u><\/p>\n

\n“Finally, we urge DTSC to
\nbear in mind that MCLs are only as health protective as is technologically and
\neconomically feasible. They are not truly health protective standards, and it is
\ninaccurate to state or imply that water meeting MCL levels is \u201csafe.\u201d In the
\ncase of TCE, which has both an MCL and a Public Health Goal (PHG), we urge you
\nto use the PHG as the basis for decisions to post signs along the creek, and as
\na cleanup level for creek and well water.”<\/i><\/o:p><\/span><\/div>\n

\nRegarding health information on 1,4-Dioxane<\/u><\/p>\n

\n
<\/span><\/div>\n
\n“Levels of other
\ncontaminants are also of continuing concern. 1, 4-Dioxane levels are high in several
\nwells, including an all-time high of 100 \u03bcg\/l in FC-04, a level 33 times the
\nOEHHA public health notification level of 3 \u03bcg\/l. This is of particular concern
\nin a location where children may be exposed. 1,4-Dioxane has been listed on
\nCalifornia\u2019s Prop. 65 list as a carcinogen since 1988.  Most of the human
\ntoxicology of the substance derives from worker exposure; effects of low dose
\nexposure to children are not known. Nor has OEHHA developed a child-specific
\nreference dose for this compound. 1,4-Dioxane exposure can occur through dermal
\nexposure as well as inhalation and ingestion — all plausible routes of
\nexposure for children playing in or near the creek. In short, the possible
\nimpacts of exposing children to 1,4-dioxane are not known, and DTSC must act to
\nprotect children who visit the park.”<\/o:p><\/span><\/div>\n
