Development of a Low-Enthalpy Water Resource at Whitford, East Auckland

Abstract

Understanding the ogy o f the warm groundwater resource at Brownhill Road, Whitford has i n the past limited by lack of data. A recent resurgence of interest in the resource has resulted in the col lect ion of a large amount o f new geologi cal , geochemical and geophysical information. In particular, a new gravity profile was installed to gain better knowledge of the basement structures which control the upflow of warm water. Interpretation of this profile has identified a new structure, the Polo Lane Fault, which intersects the Whitford Fault near the southern end of Brownhi11 Road.
