Water Quality Monitoring

Many pollutants all too often found in drinking water, like trichloroethylene (TCE), are proven to cause severe health problems and some, like benzene, cannot be safely ingested by humans at any level. The Lumense water quality monitor will help customers generate valuable, real-time water quality data. The sensor will be useful across a number of applications and industries -- including environmental monitoring and remediation; municipal, industrial, agricultural, and residential water analysis and treatment; and oil and gas extraction and transport.

Water quality monitoring is currently very expensive, slow, and complicated. Truck rolls and/or laboratory expenditures compose the main elements of the high cost. Current methods usually call for trained personnel traveling to potentially contaminated sites, preparing the water source for sampling, and taking samples. Samples are then transported to a laboratory for analysis, and results are typically available in a week. Costs per sample can vary widely, from $100 to $10,000 per sample, according to one analysis. The annual costs of monitoring a single well or surface water source can easily exceed $5,000. And, even then, the sample may offer only a brief glimpse of the true water quality.

Tests of the sensor platform in aqueous applications have already been conducted. Peer-reviewed research papers have been published on the use of the sensor to monitor traditional groundwater contaminants, like TCE and its various breakdown constituents. The company plans to soon conduct field trials with a sensor for monitoring chlorinated hydrocarbons like TCE, and aromatic hydrocarbons like benzene, in water. Production release of an initial water quality monitor product is scheduled for 2015.
