Domestic, industrial, and agricultural water: Once every 3 years
Groundwater Quality Testing Items
Drinking groundwater: 46 legally required items
Microorganisms: General bacteria, total coliforms, fecal coliforms, etc.
Harmful inorganic substances: Lead, fluoride, arsenic, etc.
Domestic water, agricultural water, and industrial water
Domestic water: Nitrate nitrogen, etc.

This test checks for substances (59 types) identified by the Ministry of Climate, Energy and Environment as contributors to water pollution.
Specific Hazardous Substances Test
This test targets water pollutants (32 types) that may pose direct or indirect risks to human health, property, or the growth of plants and animals, as specified by the Ministry of Climate, Energy and Environment.
Relevant Laws
Water Environment Conservation Act, Article 2
Enforcement Rules of the Water Environment Conservation Act, Articles 3 and 34, Annexes 2 and 13
Enforcement Rules of the Water Environment Conservation Act, Article 4, Annexes 3 and 13-2
Key Test Items
Metals: Copper, lead, nickel, arsenic, zinc, iron, cadmium, etc.
Organic substances: Tetrachloroethylene, trichloroethylene, phenol, etc.
Microbiological and ecological: Total coliforms, daphnia ecotoxicity, etc.
Test Purpose and Details
This test artificially contaminates the target area with bacteria and then measures the reduction rate of viable bacteria before and after the operation of the product or device.
It also evaluates bacterial growth under actual usage conditions to confirm the change in bacterial count.
Test Scope
Household appliances with sterilization functions (water purifiers, dehumidifiers, humidifiers, etc.)
Additional items can be tested upon client request.
What are Drinking Water Monitoring Items?
These are substances for which drinking water quality standards have not been established but that require monitoring—such as surveys of their presence in drinking water—to ensure drinking water safety.
Relevant Laws
Ordinance on the Operation of Drinking Water Quality Monitoring Items
Monitoring Standards and Inspection Frequency
Raw Water Sources
Corrosion index: 4 times/year
Microcystins (6 types): once every six months (normal) or 1–3 times/week (during algal bloom alerts)
