Drinking Luanhe River water is just some units that improve Luanhe River water and introduce their employees' residential areas. In order to save water in some communities, the kitchen and toilet are two sets of pipes. The kitchen is good water and the toilet is groundwater. Dagang district has not completely solved this problem.
Baoding water is introduced from the residential area of Tianjin Petrochemical Company in Dagang District. The water quality is good, cool and clear, and the taste is good. Just boiling water in a kettle will form a thick layer of scale on the kettle for a long time, so always wipe the inner wall of the kettle.
Sinopec No.4 Company also has geothermal water, which is convenient to use. Later, the Tianjin municipal government stipulated that it was not allowed to exploit geothermal water again. So it can't be mined elsewhere, and only four companies have geothermal water.
You can drink bottled water, or you can install a filter on the tap, and my home will be safe.
