Mae Pu Kha (Thai: แม่ปูคา) is a tambon (subdistrict) of San Kamphaeng District, in Chiang Mai Province, Thailand.
San Kamphaeng District, where Mae Pu Ka is located, is an area where the groundwater contains high levels of fluoride up to 4.8–15 mg/L.
[2] In Mae Pu Kha Subdistrict, it was observed that the village waterworks had been completed and piped water was available to most, if not all of its households.
Although residents have also dug wells in their compounds, these have generally been abandoned due to poor water quality and concerns over airborne pollution.
A study also reported that many rural villagers have been informed of the risks of fluorosis from drinking high-fluoride water through outreach programmes conducted by public health workers and community ambassadors.
