As part of a risk assessment, this study assessed all the intake holes used by spring water manufacturers. The main findings are summarized here. The detection rate of 10 elements, including boron, was approximately 60% or higher, and antimony was recorded at a rate of 45% or so. Arsenic, which is one of the contaminants assessed in the water quality standard for drinking water, exceeded the limit at four and three sites in the former and latter half of the year, respectively. The other contaminants were within regulatory limits. Antimony and molybdenum, which are on the water quality watch list, were also within the appropriate range. All other hazardous trace elements were recorded at a considerably lower level than the overseas standards. The non-carcinogenic toxicity risk value was obtained by dividing the lifetime average daily dose (LADD) by the reference dose (RfD) of intake toxicity exposure. The hazard quotient (HQ) was below 1/10th of the WHO limit for all elements. The risk evaluation results were below 1/10th of the WHO risk limit and therefore, raised no risk concerns, however, there is a need perform regular examinations on the elements with high detection frequency and assess their exposure amount. In the future, quality management or drinking water will require regular checks and the regulation of hygiene in the manufacturing process. Furthermore, it is necessary to monitor and manage new elements that originate in geological features.
