Excerpt from Twenty-First (Eighth Biennial) Of the State Board of Health of the State of New Hampshire, for the Fiscal Period Ending August 13, 1910 Elsewhere in this report is shown the record of the examinations of public water supplies of the state at the laboratory of the board. This record is a continuous one, covering a period of several years, and is presented in this form for reference purposes. It is the policy of this board to make such occasional examinations of our water supplies as may be deemed advisable, in order that any deterioration in the quality of a given supply may be investigated and remedial measures be inaugurated. An analytical examination of these records will show that many supplies have been materially improved. In some instances it has been necessary for the board to make a personal examination, to ascertain the topographical sur roundings of the source of the supply, in order to recommend the necessary changes to protect the supply. A few special reports will be found in connection with the general report. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
