The nitrogen and phosphorus pollution of water has the potential to become a significant environmental problem. Our recent whitepaper deals with this topic and discusses possible solutions.
A large part of the world’s population relies on groundwater for its water supply. With the growing demand for fresh water, the challenges associated with it increase as well. These include the need for more effective monitoring for issues such as groundwater recharge, water supply, drought, pollution and climate change…
New generation of UV Nitrate Sensors
Nutrient monitoring is becoming more important as time goes on – as human activity increases the natural amount of nitrate in water, plants and organisms are more and more negatively affected.
Current nutrient monitoring relies on low temporal frequency monitoring and spot-checking, which are vulnerable to uncertainties and less representative of the waterbody. They also aren’t equipped to measure episodic events, which are time sensitive and unpredictable.
Monitoring is moving more towards continuous measurements, which allows for more effective pollution reduction strategies and prioritization of infrastructure investments. More data also means a better understanding of where to focus data monitoring and conservation efforts.
It is far more cost-effective to prevent contamination in the first place than it is to treat existing contamination. This has led to an increased demand for sensors that deliver continuous data, both spatial and temporal, in real-time and with a lower cost per data point.
This is why we’ve released the OTT ecoN, an affordable UV nitrate sensor designed for optical determination of nitrate (NO3-N) in fresh surface and groundwater. Here’s why you should consider the OTT ecoN for your stations in the field.

The primary activities taken to assure and control data quality are aptly called quality assurance and quality control. Determining the “true value” of a water quality measurement is an important fundamental of any QA/QC program. To determine the true value, many professionals apply a second means of measuring the parameter of interest, such as another instrument that is kept serviced and calibrated just for quality control purposes or a grab sample that is evaluated using a trusted laboratory technique. Instruments such as HYDROLAB‘s produce high quality data for many applications and by leveraging the HYDROLAB Operating System you can maximize uptime with streamlined calibration tasks
Good QA/QC programs require robust calibration procedures that ultimately provide valuable information about, and confidence in, the instrument’s performance. The QA/QC Tech note highlights key information made available during a HYDROLAB multi-parameter water quality sonde calibration.
