## Water quality

The Environment Agency measure water quality of the river systems in England. Each is given an overall ecological status, which may be one of five levels: high, good, moderate, poor and bad. There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of invertebrates, angiosperms and fish. Chemical status, which compares the concentrations of various chemicals against known safe concentrations, is rated good or fail.

Water quality of the River Slea in 2019:

| Section | Ecological Status | Chemical Status | Overall Status | Length | Catchment | Channel |
| - | - | - | - | - | - | - |
| Slea (Kingsley to Sleaford) | Moderate | Fail | Moderate | 6.79 km (4.22 mi) | 31.326 $km^2$ (12.095 sq mi) | |
