WATER SUPPLY OF WESTERN PENNSYLVANIA.

WATER SUPPLY OF WESTERN PENNSYLVANIA.

All over Western Pennsylvania new towns are constantly springing up. Some have become cities; some are incorporated villages that will soon attain the same rank. Although their growth has been rapid, it has not been of the mushroom sort. These centres of business and population have come to stay—a fact which gives rise to the problem as to how they are to be supplied with water for domestic and manufacturing uses and for fire protection. At present some are dependent on springs and wells; others, on streams and creeks. These, however, with the growth of the cities and towns, are becoming contaminated. Sewage and seepage have polluted the wells, springs and streams, and what these have left unharmed the waste from mines, mills, and factories has not spared. When to this is added the decrease in the water supply itself, consequent on the destruction of the forests, the difficulties of the situation are considerably augmented in general, as well as in particular instances. Some cities, such as Dubois, for example, have solved the problem by running a costly tunnel under mountains till pure water is reached, while others have undertaken the task by filtering the water before delivering it to the consumer. Under this head come the two towns of Leechburg and Apollo, which up to the present have been in the habit of taking water from the Kiskeminetas river, which bears the evil reputation of being one of the worst in the State, on account of the enormous body of pollution which is daily discharged into it from mines and mills—to say nothing of the supply being in the habit off running short. To remedy this evil, the Pennsylvania Water company is, now building a water plant for the service of these two towns. The source. of this system will he the Bear creek, whose waters will be purified by being passed through a sand filter—the first of the kind ever seen in that part of Pennsylvania, and one of the few installed for the use of small cities. For the sake of the other towns and villages round about, it is to be hoped the experiment will turn out to be a success.
