Dust Monitoring is commonly used to measure and analyse the level of dust that is present in the air of a particular area with the intention of creating a risk management plan to keep those working in the area safe, avoiding high levels of exposure that may be harmful. This is particularly important for quarries and construction sites as these are areas where the ground can often be unsettled, leading to an increase of dust particles in the surrounding air.
At Crestwood Environmental, we carry out a range of dust surveys and monitoring using equipment that provides accurate measurement of inhalable dust from filter papers using a microbalance with a readability of 0.001mg. This will be an important tool to assess work exposure to dust and will be critical with the changing HSE regulations regarding acceptable levels of dust exposure.
A range of water analysis can be undertaken and tailored to the specific needs and information required by the client. These analyses can include:
- pH: The pH of water measures its acidity or alkalinity. A pH of 7 is neutral, while a pH below 7 is acidic and a pH above 7 is alkaline.
- Redox: The redox potential of water measures the balance of oxidising and reducing agents in the water. A high redox potential indicates that the water is oxidising, while a low redox potential indicates that the water is reducing.
- Conductivity: The conductivity of water measures its ability to conduct electricity. The higher the conductivity, the more dissolved ions are present in the water.
- Salinity: The salinity of water measures the amount of salt dissolved in the water. The higher the salinity, the more salt is present in the water.
- Anions and cations analyses: Anions are negatively charged ions, while cations are positively charged ions. The anion and cation analyses measure the concentrations of these ions in the water.
- Total elemental concentrations: The total elemental concentrations measure the concentrations of all of the elements present in the water.
- Biological oxygen demand (BOD): The BOD of water measures the amount of oxygen that is consumed by microorganisms in the water over a period of time. The higher the BOD, the more organic matter is present in the water.
- Chemical oxygen demand (COD): The COD of water measures the amount of oxygen that is required to chemically oxidise the organic matter in the water. The higher the COD, the more organic matter is present in the water.
These are just some of the many water analyses that can be undertaken, the specific analyses that are performed will depend on your needs and the purpose of the analysis.
