    The samples are tested at the Emergency Public Health Lab- oratory, South Parks Road, Oxford, and I think it may be of interest to set forth the detailed remarks, made by the Analyst, concerning these water samples, viz. :— No. Parish Probable No Result or District of B.Coli of Remarks of Analyst per ioo ml. Sample i. Aynho i Bad Coliform bacteria should not be detectable in ioo c.c. sam- ples of chlorinated water. The chlorination is apparently in- efficient. Part of the contam- ination is due to organisms of faecal origin. 2. Aynho 13 Bad This water is heavily contam- inated. Some of the contam- ination is due to organisms of faecal origin. The chlorination is obviously inefficient. The water is unfit for domestic use. 3. Aynho I Bad Coliform organisms should not be detectable in 100 c.c. of chlorinated water. As coliform organisms of faecal origin are still present the chlorination is inefficient. 4. Aynho 0 Good This water falls into Class 1 of Ministry of Health's grading 5. Aynho 0 Good ditto 6.
