Overview
The Hach m-ColiBlue24 Economy Kit is useful in testing water for bacteria, especially E. coli and coliforms. It can be used to monitor well water, drinking water and water that has been chemically processed. Features color-coding between E. coli and coliforms, and gives optimal recovery to injured organisms. It can differentiate colonies easily throughout testing and potentially minimize the growth of bacteria.
Benefits
- Read and confirm results in 24 hours
- Enumerate total coliforms and E. coli on one petri dish
- Conduct emergency testing and routine monitoring
- Get superior sensitivity - 1 CFU/100mL
- Differentiate colonies easily - red and blue indicate total coliforms and blue specifies E. coli
- Get optimal recovery of stressed and injured organisms
- Minimize background growth of non-coliform bacteria
- Eliminate special equipment and ultraviolet lamp
- (200) 0.45 m PALL Metricel GN-6 Membranes
- (200) 50 mm PALL petri dishes with nutrient pads
- (200) m-ColiBlue24 glass ampules

From Pans to Buoys: Advancing Reservoir Evaporation Rate Monitoring in Texas
In warmer climates like Texas, high reservoir evaporation rates can lead to declines in water level and water availability during droughts, making monitoring essential in order to ensure water security during times of scarcity. 
 
According to the Texas Water Development Board (TWDB), evaporation rates in Texas were previously based on data collected from a sparse network of Class A evaporation stations, dating back to the 1960s. These pans were stationed near reservoirs and still remain a widely accepted standardized approach to measuring evaporation rates on land. 
 
Monthly pan-to-lake coefficients were developed in the 1980s to connect the data collected from the pans to known lake conditions, extrapolating evaporation rates of the lakes using the pan data.

The United Kingdom has grappled with wastewater management problems for decades. Although sewage treatment in the 20th century allowed many rivers, including the tidal Thames, to have healthy fish populations, combined sewer overflows into rivers–most commonly during heavy rainfall–affected water quality and occasionally even killed fish. 
 
Problems reached a head in 2012 when multiple infractions of European urban wastewater treatment laws threatened costly fines, on top of the environmental cost of repeated sewage spills into British rivers. 
 
Fast forward to 2025, and after a decade of construction work, London’s Thames Tideway Tunnel , affectionately dubbed the “super sewer”, is now fully activated and ready for testing.

In one history, Whangārei Harbor, nestled in the lush hills of New Zealand’s North Island, gets its name from the Māori, “waiting for the breastbone of the whale.” It seems fitting, then, that it’s now home to state-of-the-art acoustic monitoring buoys listening for marine mammals around the clock. 
 
In September 2024, a team from Auckland-based underwater acoustics firm Cetaware Ltd installed NexSens buoys in Northport, a major commercial port at the entrance to the Whangārei Harbor. 
 
The first buoys to be installed by Cetaware in a permanent setting running 24/7, they use real-time artificial intelligence (AI) models to passively sense Delphinidae–from common dolphins to orcas.
