Rivanna Water and Sewer Authority is among the leading water utilities when it comes to managing algae and the harmful toxins they sometimes produce. We use an adaptive management approach which takes into consideration the unique “personalities” of each of our water supply reservoirs.
We obtain water quality data on a regular basis so we can respond in real time and stay ahead of the harmful algae blooms (or HABs) with treatment before they get carried away in the reservoirs and cause problems at the water treatment facilities. And we have a commitment to long-term monitoring so we can evaluate trends and continue to refine our approach.
In 2014, Rivanna contracted with DiNatale Water Consultants, a group of foremost leading experts in limnology (the study of lakes), to take an in-depth look at our reservoirs and make recommendations. At May’s Board meeting they gave an informative presentation to the Board and the audience. They gave a thumbs up to our current management strategies, but would like share potential new approaches after more data collection. One important question we are asking: are there alternatives to chemical treatments in the reservoirs?
In the next several months, they will share a less technical version that will be website and mobile-device friendly. After they obtain more information throughout the summer, they will submit their final report early in 2017.
In the meantime, we will continue our in-lake management strategies to minimize HABs that helps to allow us to provide water that is safe, clean, and reliable for our community!
