Watersheds include rivers, streams, lakes and the terrestrial networks around them. Watershed is a source of drinking water and domestic water, as well as a source of irrigation water in many areas. Therefore, the water quality of the watersheds and rivers is vital to a healthy living environment for human beings. In addition to natural sources of pollution such as animal waste, many watersheds and rivers are subject to some human-induced pollution caused by modern urban development, such as industrial wastewater, plastic waste, etc. In monitoring guidance for rivers of UK's Joint Nature Conservation Committee(JNCC), the monitoring indicators for river water quality are mainly organic pollution, active phosphorus, nutrient diatom index and acidification.
Alfa Chemistry has advanced analytical instruments that measure multiple indicators of water quality in rivers and watersheds in compliance with related regulations. For example, gas chromatography and liquid chromatography are used in series with a variety of detectors, such as UV detectors, flame ionization detectors, and mass spectrometers.
Alfa Chemistry offers the following analytical testing services, including but not limited to:
Total coliforms, total number of colonies, heat-resistant, coliforms, escherichia coli, staphylococcus aureus, etc.
Physical and chemical indicator
pH, turbidity, total hardness, total dissolved solids, total alkalinity, SS, color, phosphate, benzene (BTEX), odor, water temperature, conductivity, suspended solids, total nitrogen, total organic carbon , dissolved oxygen, petroleum and animal and vegetable oils, anionic surfactants, etc.
Sulfate, cyanide, fluoride, chloride, bromide, iodide, carbonate, bicarbonate, etc.
Nutrients and organic indicator
Ammonia nitrogen, permanganate index, chemical oxygen demand (CODCr), biochemical oxygen demand (BOD5), nitrate (in terms of N), nitrite (in terms of N), etc.
General chemicals include asbestos, nitrate/nitrite, turbidity, cyanide, fluoride, etc. Among them, nitrate is a common pollutant mainly found in groundwater. Because nitrate can interfere with the ability of blood to carry oxygen, high nitrate concentration is especially dangerous for infants under six months.
