Excerpt from Investigation of the Pollution and Sanitary Conditions of the Potomac Watershed: With Special Reference to Self Purification and the Sanitary Condition of Shellfish in the Lower Potomac River In the exercise of its constitutional powers, the Congress of the United States has, during the century and a quarter of its existence, passed numerous laws regulating the use of the navigable waters of the country as highways of interstate commerce. There is, however, so far as is known, no Federal law dealing with the pollution of interstate streams. Those who have suffered injury in person or property in consequence of such pollution must, it moms, ground their right to redress on the general principles of the common law or on statutes of the States.
