sampling program and could look at 25 off-site wells , but not before the end of the third round of sampling . After much discussion it was agreed the wells to look at were those down or cross gradient . EPA expressed the opinion that DDRW-WB should be looking at these private wells (at least the contaminated ones) monthly. DDRW and the State RWQCB disagreed. The question of who was responsible for the carbon tetrachloride and chloroform in the Rose and Robertson wells came up . DDRW Tracy stated it does not feel it is responsible and that we have sufficient analytical data to support our claim. The question was asked of the regulators , 'Who is responsible to follow this up (carbon tet/chloroform pollution) ? ' State water said they would talk to the industrial site manager who has some sites due south of the Rose well , which might be responsible for the chloroform. No one had any idea where the carbon tet might have come from, although , it was suggested by DDRW Tracy that it may have emanated from above ground storage tanks at the tip of the DDRW triangle , in the old railroad town of Lyoth . Everyone expressed concern for the Rose ' s and Robertson ' s and it was suggested and agreed to that DDRW Tracy provide bottled water to the Rose ' s . DDRW Tracy said we would not at this time agree to provide bottled water for the Robertson ' s because this might set a legal precedent and make us responsible for the carbon tet and chloroform problems , but we would discuss this with our legal staff for a final decision . DDRW environmental staff asked if RWQCB would provide the information on the industrial sites south of the Rose ' s on Banta Road. RWQCB said it was public record data and DDRW-WB said we would get Woodward-Clyde to check it out . The EPA suggested that two quarters of data are not really representative of a trend as far as the plume goes ; everyone agreed we need more data. No one suggested a direct course of action to control the spread of the plume other than collecting more data. When asked , the County representatives said it should be possible to put extraction wells in on the highway (Banta Road) easement . The RWQCB agreed to take a couple more rounds of samples at the Rose and Robertson residences , but that would be the limit of their involvement . The EPA praised them for doing what they had already and felt they went above their requirements !
