Excerpt: about this time the particular parasite or bacillus which causes typhoid fever was discovered, the principal means and modes of transmission of the disease were studied and the knowledge of its preventability widely disseminated. However, it was not until about 1890 that active steps were taken to improve many water supplies in this state. In 1892 the city of Newark abandoned the use of the Passaic River as a source of water supply, the water supply thereafter being taken from the Pequannock River. The average typhoid death rate in Newark for the 10 years prior to this change had been about 64 per 100,000 population, for the IO years following the change the average rate was about 22, or one-third the former rate. In 1899 the water from the Passaic River was again used temporarily with a consequent increase in the typhoid death rate. Since then the rate has declined to a much lower point. In 1896 jersey City also abandoned the lower Passaic River as a source of public water supply, thus reducing the typhoid death rate per 100,000 population from an average of 79.9 for the 5 previous years to an average of 2I_8 for the 7 succeeding years. Curiously enough, the last large city in New Jersey to take the necessary steps to improve its water supply for the purpose of making the water safe for human consumption was the State Capital. Soon after the inauguration of Commission Government in Trenton, the newly 'elected commissioners made it financially possible for the city to construct the much needed water filtration plant.
