The Lawrence Experiment Station, Located at the easterly end of north canal on the Merrimack River, was established in 1887 to carry out the provisions of an act of an act of the Legislature passed the year previous which provided for the protection of the purity of inland waters. This station operates under the state board of health which is required to advise the authorities of cities and towns, corporations, firms or individuals, on matters pertaining to water supply and sewage disposal. Here experiments are conducted to determine the best practicable methods of purification of drainage and sewage or disposal of the same.
Until 1935 all bacterial analyses of waters, sewages, wastes and shellfish for the whole state were made at this station. Another Station is now located at the Westfield State Sanatorium which handles some of the samples from the western part of the state.
