It is hereby recognized that the presence of large volumes of water in anthracite coal formations involves serious wastage of the fuel resources of the Nation, and constitutes a menace to health and safety and national security. It is therefore declared to be the policy of the Congress to provide for the control and drainage of water in the anthracite coal formations and thereby conserve natural resources, promote national security, prevent injuries and loss of life, and preserve public and private property, and to seal abandoned coal mines and to fill voids in abandoned coal mines, in those instances where such work is in the interest of the public health or safety.
