Burford Jurassic Operational Catchment
About
The Burford Jurassic Groundwater Body (GWB) describes part of the Great and Inferior Oolite geological strata that lie beneath the Cotswolds. The Oolites are limestone aquifers - water-bearing permeable strata that provide a high level of storage. Since they support regionally important drinking water supplies these aquifers are classified as Principal Aquifers. The Great and Inferior Oolites are limestone geology separated by the Fullers Earth and consequently the Inferior Oolite is confined under the Great Oolite in much of the Cotswolds. Where the Inferior Oolite is confined it is generally protected from vertical migration of chemicals used at the surface. Whilst the Great Oolite is exposed at the surface for the major part of the Burford Jurassic GWB, the Inferior Oolite is exposed at the surface just in the north western areas of the GWB. In these exposed areas the Oolites are susceptible to vertical migration of chemicals, including fertilisers.

Challenges data for Burford Jurassic Operational Catchment
Reasons for not achieving good status by business sector
The issues preventing waters reaching good status and the sectors identified as contributing to them. The numbers in the table are individual counts of the reasons for not achieving good status with a confidence status of 'confirmed' and 'probable', where the latest classification is less than good status. There may be more than one reason in a single water body. Note, table does not include reasons for deterioration.
