WATER / WASTEWATER
High-level water testing software
Aquaread is pleased to announce the launch of PROLINK, a professional PC suite specifi cally designed with the AS-PRO in mind. This new platform features a clean, graphical user interface and introduces several exciting new features.
The dashboard provides a wealth of information related to the Aquasonde, including the serial number, software version, and estimated battery life. It is also where the user can set the sonde’s logging regime, event triggers, and customizable data averaging. Each section in the dashboard can be customized by clicking on the cog icon to access its option settings.
The new calibration section displays all currently fi tted sensors as icons at the top of the screen. By clicking on one of these icons, the user can view the sensor’s previous calibration report values and available calibration options. Once in calibration mode, the live reading for that parameter, along with the temperature, is shown. Below this information, a live graph displays the trend of the sensor in the calibration solution, helping to assess the stability of the readings before beginning the calibration, which contributes to achieving a more accurate calibration.
One of the completely new additions to the PC application is the customizable live data view, allowing users to log data with live data graphs displayed on the screen. Users can switch different parameters on and off to customize the view, enabling them to focus on the behavior of their chosen parameters.
Currently, PROLINK works with Aquasondes, including the new AS-PRO. However, specifi c sections for both the Aquaprobe and Leveline will be added as work on these devices progresses. PROLINK will automatically download and install any updates each time the software is opened, ensuring that users are always running the most up-to-date version without needing to manually check for updates.

Submersible water level transmitter with increased versatility
The Solinst Model 301 Water Level Temperature Sensor provides highly accurate water level transmission using multiple protocols for a wide variety of applications. With the addition of a simple adaptor, the 301 WLTS is now even more versatile with the ability to program it with 4-20mA protocol. This adds to its options that already include Modbus and SDI-12 compatibility.
The WLTS is a compact, all-in-one submersible hydrostatic level transmitter that provides continuous, stable water level and temperature readings, with options for absolute and vented pressure sensor setups. The durable water level pressure sensor provides 0.05% FS accuracy with automatic temperature-compensated readings. There are six pressure ranges (5–200 m), with communication cable assemblies available in lengths up to 300 metres.
The water level pressure sensor and temperature sensor are enclosed in a narrow, robust 22 mm x 192 mm (7/8” x 7.55”) 316L stainless steel housing. Double o-ring seals prevent leaks, and a Faraday cage design protects against power surges and lightning. Each probe features a removable nose cone for optional use of the 1/4” NPTM threaded connection.

MIXING PFAS AND MICROPLASTICS INCREASES TOXICITY, NEW STUDY CLAIMS
A new study has revealed that perfl uoroalkyl substances (PFAS) and PET microplastics are more toxic (to freshwater species, at least) when combined.
Focusing on water fl eas (Daphnia magna), a sentinel species in freshwater ecologies, the study highlights alarming developmental and reproductive impairments.
In particular, the researchers highlighted the compounding effect of exposure, whereby fl eas with historic exposure experienced multiplied impacts.
Maldevelopment, synergistic toxicity, compounding impacts
The study demonstrated exposure to PFAS and microplastics mixtures delayed sexual maturity, stunted growth, and reduced fecundity in Daphnia.
Approximately 41% of effects were judged to be synergistic, likely stemming from interactions between the negatively- charged microplastics and PFAS that enhanced retained uptake.
Daphnia with a history of exposure to pollution exhibited reduced resilience to chemical mixtures compared to naïve populations.
Why PFAS and microplastics uniquely impact freshwater ecosystems
Both PFAS and microplastics are environmentally persistent and bioaccumulate, wreaking havoc in freshwater contaminated by waste streams.
PFAS disrupt endocrine functions in freshwater species, impair reproduction, cause developmental abnormalities, weaken immunity, and increase mortality.
Microplastics, when ingested by microorganisms, block digestive systems and in water, leach endocrine disruptors, like bisphenols, brominated fl ame retardants and phthalates.
Regulating mixtures as well as individual pollutants
The fi ndings of the study underscore the critical need to regulate chemical mixtures rather than simply assessing pollutants in isolation.
Further, PFAS and microplastics frequently co-occur in natural environments, such that their actual impacts (and therefore, their regulatory priority) are probably underestimated.
For instance, while they are regulated in drinking water at specifi c limit, if their synergistic toxicity is ignored, compliant levels may actually be unsafe.
