HAB Aquatic Solutions, LLC specializes in improving surface water quality through the use of aluminum-based products (e.g., alum and sodium aluminate). HAB’s research and development efforts improved upon traditional alum treatment approaches by developing treatment systems to address the unique challenges of today’s water resource management projects.

We are a full service alum treatment company. HAB has over 60 years of combined experience and provides the most comprehensive alum services available, including pre-project water quality monitoring, algae identification, chemical dose determination, GPS-guided chemical application, alum injection systems for the treatment of storm water/stream water, and post-project water quality monitoring and evaluation. HAB’s co-founders (John Holz and Tadd Barrow) are two of only a handful of scientists qualified to provide complete alum treatment services: from dose calculation, to application, to project evaluation.

Wapato Lake is a shallow, 34-acre urban lake located in the City of Tacoma, WA. The lake has a long history of poor water quality with the first closure to recreational use occurring in 1942. Problems at the lake have ranged from swimmers getting rashes, to bad odors, to heavy algae blooms, and to the toxic algae blooms that have been common in recent years. Excessive amounts of the nutrient phosphorus is the main cause of the toxic algal blooms.  Internal phosphorus loading (leaching from the lakebed sediments) is significant in the lake and phosphorus is high in the sediments and available to be released into the overlying water column.  HAB Aquatic Solutions will be conducting a buffered alum application over a three period in mid-May.  The application produces a “floc” that settles to the bottom of the lake.  The floc has sites where phosphorus in the sediments become chemically bound as it leaches from the bottom.  The floc effectively intercepts and binds the phosphorus, which makes it unavailable for the algae to use for growth.  The goals of the project are to dramatically reduce the internal loading of phosphorus from the sediments, lower the amount of phosphorus available to algae in the water, reduce the amount of algae and associated toxins and remove any recreational restrictions at the lake.
