Establishing a citizen-science groundwater monitoring network for Scarborough & Kommetjie, Western Cape
The report details the creation of a citizen-science groundwater monitoring network in Scarborough and Kommetjie, Western Cape, commissioned by WWF South Africa. Following a significant increase in borehole drilling during the 2015-2019 drought, the study employed desktop searches and a hydrocensus of 105 properties to identify groundwater users and monitoring sites. Four Solinst Leveloggers were deployed to track water levels and temperature, with data integrated into the Table Mountain Water Source Area Groundwater Dashboard. Findings indicate that borehole depths range from 1 to 60 metres, with water levels between 2.5 and 4 mbgl and electrical conductivity values between 54.8 and 150.7 mS/m. The report recommends continued stakeholder engagement and quarterly data downloads to ensure sustainable groundwater management.

The document describes the selection of four new groundwater monitoring areas—Brackenfell, Constantia/Bergvliet, Noordhoek, and Scarborough/Kommetjie—to support the City of Cape Town's water diversification efforts. Selection was based on borehole density, drilling activity during the 'Day Zero' period, equipment accessibility, and potential points of concern. These sites supplement existing monitoring in Newlands and Epping Industria to manage risks associated with unregulated groundwater abstraction under a changing climate.
