Continuous Instream Monitoring

by FTS     based in Victoria, BRITISH COLUMBIA (CANADA)

Turbidity in natural waters is recognized as an important indicator of its environmental health, and because it's a good surrogate for suspended sediment, monitoring turbidity has always been the "holy grail" for hydrologists. But because of earlier technology, "turbidity" has traditionally been a "bad word". The DTS-12 turbidity sensor is the first sensor to make turbidity monitoring practical, and no longer difficult, inaccurate, expensive, or labor-intensive. Turbidity is the cloudiness or murkiness of water caused by suspended organic or inorganic materials. Turbidity in natural waters is recognized as an important indicator of its environmental health.

Data analysis and visualization tools for monitoring well decommissioning

by C Tech Development Corporation     based in Henderson, NEVADA (USA)

Contaminated groundwater sites worldwide are engaged in regular sampling of monitoring wells at a typical cost of $1,500 per well-sampling event. On most sites, many wells are redundant or geostatistically insignificant and can be decommissioned.
EVS-PRO and MVS`s Well Decommission module analyses all available data and quantifies the impact on site assessment quality associated with removing each well. The impact of removing a well is quantified in terms of its impact on the geostatistical plume extent.
During remediation plumes are shrinking and may drift. This can necessitate decommissioning of some wells and adding new wells. C Tech`s well decommissioning and DrillGuide© technology provide the tools to properly monitor and guide the remediation efforts at the lowest possible cost.

Water measurement systems & sensors for water quality monitoring

by Isodaq Technology - Hydro-Logic Group     based in Bromyard, UNITED KINGDOM

Effective water quality monitoring is the key to environmental protection of watercourses and for reliable process control and wastewater treatment.  Discharge consents under EPR regulations dictate that water quality monitoring is undertaken to ensure that consented parameters are below the consented concentrations.  Traditionally this has been done using water quality sampling methods but increasingly automatic water quality measurement sensors linked to real-time telemetry is seen as the most reliable and timely means of ensuring that treatment processes are operating efficiently and that EPR compliance is maintained.

Dust monitoring and Sand Storm Monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

The frequency and intensity of dust and sand storms in many parts of the world are steadily increasing due to droughts and climate change. The severity of such storms is anticipated to increase over the coming years. These dust storms may last hours or days and cause huge damage and imposed a heavy toll on society with its physical effects, such as visibility reduction, heavy winds, red sky, hailstone and severe lightning. Such Dust storms, have a negative impact on human health, and industrial products and activities. They reduce visibility, layer on skin and cloths, infiltrate buildings and find their way into food and drinking water leaving a permanent sandy feeling in your mouth. Traditional dust monitoring instruments whether they be purely filter based gravimetric samplers or continuous monitors utilising Tapered Element Oscillating Microbalance (TEOM) or Beta Attenuation (BAM) simply are unable to cope with the high dust loads created by these storms. The filters on these instruments are quickly clogged and no further measurements are possible until a service technician visits to replace filters and filter tapes. In dust storm events this is impossible. Therefore, over the past few years a need for alternate technology which are non filter based, can cope with extremely high dust loads, require minimal maintenance and can operate off solar power has been employed in regions such as the Gobi Desert of China for the continuous monitoring of dust storm events. These instruments have demonstrated that an instrument can measure dust storm events with maintenance performed only once every 12 months. That it is possible to communicate remotely and that these systems can not only provide an early warning for dust events but have the accuracy and sensitivity to be an extremely useful tool in gauging hourly changes of visibility. Infact such instruments have been utilised by a number of EPAs around the world, including all Australian EPAs for the purpose of measuring ambient visibility as well as providing an accurate indication of rising dust events.

Analysis of Herbicides in Drinking Water

by Sigma-Aldrich Co., LLC     based in Bellefonte, PENNSYLVANIA (USA)

Herbicides are used throughout the world to combat the growth of unwanted plant life. These polar compounds are hydrophilic, so they may find their way into drinking water sources. While gas chromatography has historically been the preferred technique for analysis of herbicides in water samples, the use of LC-MS/MS for this application is gaining acceptance. This is due to the power of MS/MS to provide detailed identification of multiple analytes, but also in part due to the variety of HPLC stationary phases that are available. In particular, several HPLC phases are available that provide great retention and peak shapes for polar analytes, such as herbicides, even under mostly aqueous mobile phase conditions. The combination of these factors may possibly eliminate need for time-consuming sample preparation.

APHA Color #3020

by Guided Wave Inc,     based in Rancho Cordova, CALIFORNIA (USA)

Measurement of APHA color either on-line or in a laboratory setting using a photometer. Background: APHA is sometimes referred to as the Platinum Cobalt (Pt/Co) or Hazen scale. Also referred to as a “yellowness index”, the APHA color scale is a common method of comparison of the intensity of yellow-tinted samples to assess the quality of liquids that are clear to yellowish in color. Originally developed to determine the purity of municipal water supplies, it is now used as a metric for purity in the water, chemical, oil, plastics, and pharmaceutical industries. APHA color quantifies the appearance of trace amounts of yellowness, which is a visual indicator of product degradation due to exposure to light or heat; the presence of impurities and negative effects of processing. As such APHA color is often used as a product release specification. APHA is a single number yellowness index. The units are based on a dilution of a 500ppm solution of PtCo.

Water Treatment Solutions for Turbidity Removal

by Adedge Water Technologies, LLC     based in Buford, GEORGIA (US) (USA)

Turbidity is a measure of the loss of light transmittance through a liquid due to suspended particles. The more particles in the water, the murkier it looks or the higher the turbidity. This is a measure of the quality of the water. It is measured in units called Nephelometric Turbidity Units (NTU). Turbidity can be caused by run off after a heavy rain as erosion washes soil into a river or lake. It is often increased in the spring and fall when the water temperature at different levels in a lake change causing a turnover of those levels, bringing sediment, plants, and algae to the top.

Waste water treatment plants Personnel Safety & H2S filter management

by Chromatotec Group     based in Val de Virvée, FRANCE

Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. As a result of the confinement of the waste water stations, toxic components such as H2S and Methylmercaptan increased. Safety of employees on such working sites has therefore become of major problem. To fight this hazardous pollution, air filtering systems have been installed. For the station managers, personal safety coupled with the need for constant air quality control and filter change has been a heavy task.
