Traditional production in craft villages has released large amounts of wastes into the environment, which may pose negative impacts on human health and ecosystems. This study was conducted to assess the current state of the water quality in the Thanh Luong rice vermicelli and fresh noodle craft village. Water samples at 12 sites were collected for determination of BOD 5 and COD values. Social survey was also performed at 19 production and 30 non-production households. The results showed that BOD 5 and COD values in water samples varied from 29 to 2620 mg/l and from 91 to 3600 mg/l, respectively. 100% of wastewater samples with BOD 5 and COD values exceeded the regulation limits (QCVN 40: 2011/BTNMT). The highest BOD 5 and COD values in wastewater were 37 and 18 times higher than the limits regulated by QCVN 40: 2011/BTNMT, respectively; those in surface water were 23 and 25 times higher than the values set by QCVN 08-MT:2015/BTNMT and 1/2 of the groundwater samples with COD exceeded the QcVN 09-MT:2015/BTNMT. The results of social survey demonstrated the medium effectiveness of the local environmental management (43% of household questionnaires) and low to medium awareness of local community for environmental protection. Solutions for environmental protection in Thanh Luong village have also been discussed in this study.
