Where We Are Going

HAB Innovations continues striving to improve the management of valuable natural resources through our focused research and development efforts.  Current ventures are aimed at:

  • Further increasing alum dose precision
  • Optimizing alum application timing & strategy
  • Technologically enhancing the delivery of alum to the lake sediments
  • Reducing restoration costs
  • Developing new chemistries for phosphorus inactivation
  • Integrating alum with other lake management techniques to gain additive improvements in water quality & lake user experiences

We are also working on multiple innovations aimed at tackling other less-understood sources of environmental pollutions that have long been unaddressed.  It’s been a fun and rewarding ride so far and we will continue to define new horizons here at HAB Innovations!

What We Have Done

HAB Innovations co-founders (Dr. John Holz & Tadd Barrow) have a long history of novel contributions to the fields of aquatic resource management and restoration.  As applied research scientists on the faculty of the University of Nebraska, our combined efforts advanced the understanding of topics such as:

  • Waterbody response to various pollutants (e.g., nutrients, sediment, herbicides)
  • Appropriate & realistic water quality goals
  • The role of internal phosphorus loading in lakes
  • The relationship & dynamics between algae & phosphorus
  • Aquatic community stability & resilience
  • Fish behavior in response to various stressors & pollutants
  • Fish habitat use patterns & selection criteria
  • Toxic algae & public health
  • Effectiveness of numerous lake management techniques, including:
    • Sediment nutrient inactivation (e.g., alum, iron salts)
    • Dredging
    • Sonication
    • Aeration/water column mixing
    • Algaecides & Herbicides
    • Bottom barriers
    • Microbes
    • Barley straw

Holz and Barrow have integrated this knowledge base into their lake restoration and phosphorus inactivation (alum) work in some important ways that have:

  • Increased accuracy & cost efficiency of alum doses
  • Improved alum application strategies to increase effectiveness & longevity
  • Further prioritized aquatic habitat improvement in restoration projects
  • Increased monitoring efforts to document project benefits
  • Revolutionized alum application technology, which has:
    • Maximized environmental & human safety
    • Improved alum floc quality & phosphorus binding capacity
    • Increased both short & long-term sediment phosphorus flux control
    • Reduced application costs
