Discharge permits by pollutant and parameter

Every discharge permit that carries a numeric limit does so against a named parameter -- a pollutant such as lead or ammonia, or a property of the discharge itself such as temperature or pH. These pages group the current register by parameter: which permits carry a limit for it, where, and how many of those permits have a recorded exceedance on file.

By parameter

The 500 parameters carrying the most permits with a limit. A parameter with fewer than three permits carrying a limit for it does not appear here or at the state and watershed level.
