Water Monitoring

Water Monitoring

Construction and related industries can have an effect on water quality.

There are several types of Water Quality Monitoring. These include:

These tests all monitor water quality by rating the purity of the water, and test for different ways in which construction can effect the water quality.

Remote Water Quality Monitoring

Remote Datum can help monitor the effects construction has on water quality easily, providing you with easy access to your data, as well as text and email alerts when pre set levels are exceeded. We install our equipment and help construction industries to monitor their effect on the quality of nearby water bodies.

Groundwater Monitoring

Groundwater Monitoring has several benefits:

Groundwater Monitoring Benefits in Construction Industries

By carefully monitoring groundwater during construction work it is possible to minimse the effect of works and ensure that groundwater supplies are not polluted. If pollution occurs it also ensures that companies are aware and that work can be undertaken to rectify and prevent futher pollution.

Turbidity Monitoring

Turbidity Measurement, Turbidity Probe, Turbidity Monitoring,

Turbidity is the cloudiness or haziness of a fluid by suspended solids that are sometimes invisible to the naked eye. Turbidity measurement is a key test of water quality.

The suspended particles absorb heat from the sunlight, making turbid waters become warmer. This reduces the concentration of oxygen in the water.

Why Monitor Turbidity?

The increase in warmth and decreased oxygen concentration effects organisms that can’t survive in warmer water. By absorbing the sunlight, suspended particles raise the water temperature and kill water organisms. Turbidity monitoring therefore ensures that we prevent fish and other water organisms dying.

Additionally, the suspended particles scatter the light, thus decreasing the photosynthetic activity of plants and algae, which contributes to lowering the oxygen concentration even more.

As a consequence of the particles settling to the bottom, shallow lakes fill in faster, fish eggs and insect larvae are covered and suffocated, gill structures get clogged or damaged.

The suspended particles also help the attachment of heavy metals and many other toxic organic compounds and pesticides.

Turbidity Sensors

A turbidity sensor directs a focused beam into the monitored water. The light beam reflects off particles in the water, and the resultant light intensity is measured by a photodetector positioned at 90 degrees to the light beam. The detected light intensity is directly proportional to the turbidity of the water. The turbidity sensor utilizes a second light detector to correct for light intensity variations, color changes, and minor lens fouling. The sensers are connected to a data logger that transmits the measurements back to a web bureau or the clients server, if pre set parameters are exceeded an SMS alarm and/or email is sent to pre arranged persons and if required, an alarm may sound at the measurement location.

PH Monitoring

pH monitoring is an indicator of water quality and purity. During construction works, foreign material and substances can cause a change in pH. Changes in pH can cause long term effects on the water environment and the species that reside within it. Plants and animals are often unable to survive.

pH Measurement - How is it done?

Remote Datum provides equipment to accurately measure the effects of construction or related works on nearby water bodies. Our kits contain pH Sensors / pH Probes that autonomously collect real time data. The sensers are connected to a data logger that securely transmits the measurements back to a web bureau or the clients server, if pre set parameters are exceeded an SMS alarm and/or email is sent to pre arranged persons and if required, an alarm may sound at the measurement location.

Dissolved Oxygen Monitoring

Rivers, streams and lakes are home to a variety of fish, invertebrates, plants and aerobic bacteria, all of which require oxygen to survive. Water contains a certain amount of dissolved oxygen that allows these organisms to respire and live within it. Most of the dissolved oxygen in water comes from the atmosphere, and is distributed throughout the water body by the current and flow of the water. Algae and other aquatic plants also put oxygen into the water via photosynthesis.

Why do we monitor dissolved oxygen?

When dissolved oxygen levels are depleted, it has a major effect on the aquatic organisms found in our streams, lakes and rivers. Without enough oxygen they are unable to survive. Dissolved Oxygen Monitoring therefore gives us an indication of water quality.

What causes the dissolved oxygen levels to decrease?

One major factor that contributes to changes in the dissolved oxygen levels is the build up of organic wastes. These can enter the water via wastewater from sewage treatment plants, or through construction related projects. When these wastes decay oxygen is used up. Temperature, pressure and salinity (dissolved salt content of water) also effect the levels of dissolved oxygen.

Dissolved Oxygen Sensors / Dissolved Oxygen Probes measure the ratio of dissolved oxygen content (ppm) to the potential dissolved oxygen capacity (ppm), giving a percentage saturation.
