Keywords:Groundwater quality, Well water, Groundwater, Handle, Pho Yen city
The study was conducted in Van Phai communes in Pho Yen city to evaluate the quality of well water used in daily life. The analysis results show that most of the indicators meet the standards. However, the nitrate content of 15/21 samples, the ammonium content of 10/21 samples, the Fe2+, 3+ content of 10/21 samples and the total coliform concentration of 1/21 samples did not meet the requirements compared with the Regulations. National technique on quality of domestic water (QCVN 01-1:2018/BYT. Nitrate content 4/21, ammonium content 8/21 samples, Fe2+, 3+ content 2/21 samples, Concentration coliform total, 21/21 samples did not meet the requirements of the National Technical Regulations on Groundwater Quality (QCVN 09-MT: 2015/BTNMT). There is no significant difference between rainy season and November dry season of 2022 on the same sampling point. On the basis of assessing the quality of domestic well water, a solution for domestic well water treatment has been proposed, which basically ensures such problems as simplicity, ease of doing, durability for many years, ease of use and reuse. as well as easy to maintain
