The residential area of Kwa Zamo Kuhle in Hendrina was identified as one of the five towns in the Highveld Priority Area where an ambient air quality monitoring station should be placed. Hendrina was one of the areas identified as having a high frequency of exceedances for the PM10 daily average standard and also in terms of annual average SO2 concentrations and thus identified as a "hot spot". The site that was considered the most appropriate was Tsiki-Naledi Secondary School in Kwa Zamo Kuhle, being well looked after and secure. The station will give a good indication of ambient air quality in the town of Hendrina as there are no direct sources near to the school. There is also no direct influence of domestic fuel burning as the school is in a built-up area.
