Remediation and Reclaimation
Many fresh water sources have been degraded to toxic levels by the inclusion of industrial, agricultural, and human waste products that have been discharged into the closest body of water, accidentally or deliberately for many years.
A heightened awareness by the public of the damage that can occur to public health and the environment has given impetus to new regulations regarding the safe disposal of toxic waste and the recovery of contaminated areas.
The river Thames in the UK was declared dead 50 years ago, but thanks to energetic measures taken to clean up the river, it is now home to 125 species of fish and over 400 species of invertebrates. Seals and dolphins are often seen from the banks as the river winds its way through London.
Efforts proceed to rehabilitate the wetlands, often described as the lungs of the rivers and streams. Wetlands were often drained and filled to provide development land for housing or industrial / agricultural sites. This practice has now been reversed and many wetlands are being rehabilitated and are once again keeping rivers clean and the water fresh.
The Heron Instruments H.Oil and Sm.Oil oil/water Interface meters are used on many remediation sites to detect floating or sinking hydrocarbon layers or to confirm their absence.
The Heron dipperLog System is widely used to monitor stream levels at wetland sites.
Using the Heron dipperWave in conjunction with Heron loggers can reduce human intrusion into these sensitive waterways.
