River Pollution and EA21 Compliance
The UK water industry is starting to mobilize resources toward meeting the requirements of EA21, monitoring river water quality and identifying potential point sources of pollution to ensure the health of UK rivers for current and future generations.
EA21 sets out ambitious targets for the protection of rivers, estuaries and coastal zones in the United Kingdom. Part 5 Section 82 requires water utilities to continuously monitor water quality upstream and downstream of all storm overflow and sewage disposal works that discharge into a water course.
Regulations call for the monitoring of five key water quality parameters; pH, dissolved oxygen(DO), ammonia, turbidity and temperature. In addition, the legislation states that additional parameters may be added to the list, including organic pollution measures (COD and/or BOD) and potentially nutrients such as nitrate or even surrogate bacteriological parameters where these can provide additional context.
With more than 20,000 CSOs and over 7,000 sewage treatment works in England & Wales, the legislation creates a significant challenge to the industry in terms of installation, monitoring and continuous maintenance. However, with the right solution, this challenge can be managed—while setting utilities up for success as new measurement parameters are added in the coming years.
By choosing a flexible and modular approach to sensor deployment you can ensure your solution suits the application, no matter the parameters required. Badger Meter, with integrated s::can sensor technology, has demonstrated a successful track record in this demanding application for over 25 years across the globe.
