Pollution Control Strategies and Tributary Action Teams

A 1997 federal court case required Delaware to set pollution limits for its waterways. These limits are called Total Maximum Daily Loads or TMDLs, a term you will hear a lot in water pollution discussions. In order to meet these new pollution limits, we are identifying ways to reduce water pollution. Usually, citizens don’t

---

Total Maximum Daily Loads

When monitoring reveals that waterways do not meet Delaware’s water quality standards, they are reported on a list of impaired waterways (303(d) List). For each impaired waterway, the Federal Clean Water Act (CWA) requires states to develop Total Maximum Daily Loads (TMDLs) for the pollutants of concern. A TMDL sets a limit on the amount
