The EPA’s sampling operations follow the standard guidelines for the River, Lake and Reservoir Water Sampling (NIEA W104.51C), the Standard Guide for Sampling Groundwater Monitoring Wells (NIEA W103.54B) and the General Water Quality Testing Methods (NIEA W102.51C) which are issued by the National Institute of Environment Analysis (NIEA). For detailed sampling specifications, please visit the web links of “Water quality monitoring and sampling operations” on the EPA’s Environmental Water Quality Monitoring and Information System. In addition, sample testing is conducted in accordance with the NIEA’s testing methods. For detailed information, please refer to NIEA’s testing methods.
River:
- Important
- Junctions of main streams and important tributaries
- Other necessary points
Beaches:
In order to allow people to recognize beach water quality to consider when engaging in water activities, the E.P.A invites the Tourism Bureau, each region’s environmental bureau and related Scenic Area Administrations to join and discuss together to decide on selecting the beaches that have the greatest capacity for swimmers.
Territorial Sea:
Monitoring points were established at locations near eatuaries and recreation activity, which might affect water quality.
Reservoir:
Priority was given to locations ensuring safe operations to eliminate risks, such as when reservoirs release water. The monitoring points were determined upon factors such as the goal of sampling investigations, reservoir characteristics and resource allocation. Besides the surface water, stratified sampling was conducted at the monitoring points according to the water depth of the reservoirs.
Groundwater:
Water Resources Agency, Ministry of Economic Affairs, divided Taiwan into ten groundwater regions. The environmental protection bureaus and the Groundwater Pollution Remediation Fund Management Committee established regional groundwater monitoring wells in 20 counties and cities.
