Show I ARTESIAN WELLS. A shallow artesian well in a city is a dangerous thing. It merely gives up the surface water which comes of the last winter's storms and which may have flowed only a mile or two near the surface and may have been tainted more than fhe gravel through which it flows . uld in that distance purify. But when water which has come through a deep fissure from the mountains can at great depth, that is, at a depth below where any of the filth of a city could penetrate, be found, that water is such as the mountains hold' in reserve, and must be pure unless minerals in the hills have contaminated con-taminated It. These sources are what, near the surface, feed the streams that run down from the hills after the snows have melted. If the same fissures can be tapped lower down, the water must be the same and the chances of its continued flow much greater than in the surface streams. Unless the geologists are all in error, the waters tapped by the wells above Liberty Park come from those deep fissures and have been arrested there by a great cross fault running for some miles along the lower foothills of the great range. Above Liberty Park the water is forced up to comparatively com-paratively near the surface, so that wells from 150 to 500 feet tap them. Of their full possible capacity ca-pacity we can gain some idea from the increased volume of the Jordan after these waters find their way by subterranean channels to the river. That amount at this season of the year would make the entire flow of City creek, Parley's creek and the Cottonwoods look like thirty cents. |
