◉ Scope of Test
a. Groundwater detection at the regional level and long-term monitoring of the groundwater environment;
b. Groundwater detection and long-term monitoring of groundwater environment in contaminated plots and surrounding areas;
c. Groundwater detection and long-term monitoring of groundwater environment in drinking water source protection areas and recharge areas.
◉ Test Items
Sensory properties and general chemical indicators: color, smell and taste, turbidity, visible matter, pH, total hardness, total dissolved solids, iron, manganese, copper, zinc, aluminum, volatile phenols, anionic surfactants , oxygen consumption, ammonia nitrogen, sulfide, sodium;
