Excerpt from Simple Water Testing

Natural water is never found pure. Rain water is the purest natural water. As the rain falls it washes the gases and dust from the air. Upon striking the ground, it takes up impurities from the soil, the rocks and plants. Part of the Water flows on [the surface, absorbing more impurities. On filtering through the ground, the water loses most of its organic impurities which were absorbed from vegetable and animal de posits on the surface. As it does this, however, it also dissolves and absorbs mineral matter and gases.

Since all boiler feed - water must necessarily con tain these impurities to,a greater or lesser extent, the engineer must know how to avoid same, and this book will tell you in a clear and practical way how to do it.

It explains it all so clearly that you can analyze the water yourself, and be able to adopt proper remedies for counteracting the ill effects of such impurities.
