  • Sonic Plus Water Treatment System | Environmental Troubleshooters MN

    Sonic Plus Water Treatment System Restoring Water Quality in a Lake The Sonic Plus water treatment system is a proprietary, patent pending, portable standalone water treatment device that uses sonication technology to enhance water quality and reduce aquatic toxicity. This technology organically restores impacted water bodies and holds the potential of replacing the current practice of applying harmful chemical shock treatment to water. The Sonic Plus is a flow through device that recirculates water through the unit and discharges the treated water back into the soil, groundwater table or surface water body. This technology can be used to restore the water quality in lakes, streams, and ground water aquifers. During the past several years, the Sonic Plus has been demonstrated to reduce elevated levels of Cyanobacteria (blue-green algae) in surface water, conserve irrigation water usage, increase crop production, enhance livestock hydration, produce more farm animal offspring, increase milk quantity and quality, and improve the overall health to livestock. Agricultural Irrigation Surface Water Treatment Our patent pending Sonic Plus technology has been proven in the agricultural industry. Our initial agricultural application installed the Sonic Plus to a center pivot irrigator to conserve water usage. While this application was successful in conserving the amount of water pumped into the soil, we discovered the system also acted as a yield-enhancer for row crops. This system is now routinely used by many row crop farmers to cut their irrigation costs, while improving their crop yield per acre. The below picture tells the Sonic Plus story. Clean water irrigation technology not only conserves water but enhances row crop yield to improve the bottom line for farmers. Agricultural Irrigation Two neighboring fields: the field in the foreground used the Sonic Plus technology on a center pivot irrigator, while the field in the background (north of the road) used a standard center pivot irrigator. Note the improved health and growth rate of the crops by using Sonic Plus water enhancement. This agricultural technology is not just limited to the row crop farmer. Our technology has also been applied to livestock production. For many years, people have looked for a more natural or organic method of livestock production. Much of this organic movement has centered around the elimination of chemicals, additives and growth hormones to livestock and their food source. However, the water or hydration of the animal has been the forgotten factor. That is until now. For three years, the Sonic Plus has been installed into the water delivery system at a local diary. This system has provided a cleaner and more healthy water source for the dairy cows and the results are nothing short of astounding. The dairy saw improved health in every measurable category, birth rate, growth rate and milk production, etc. The table and graph below depict how cleaner and healthier hydration of milk cows translates to greater profitability for the dairy. Surface Water Treatment For the past 5 years, we have been using the Sonic Plus water treatment system for the restoration of surface waters that are impaired with Cyanobacteria or blue-green algae as it is commonly referred to. The Sonic Plus treatment system is suspended in the water column, so water can be continuously pumped through the proprietary sonic tube to generate sound frequencies. These sonic frequencies enhance the water’s natural physical properties and reacts as a catalyst throughout the water column to reduce toxic levels of blue-green algae. The Sonic Plus treatment system has demonstrated a significant reduction of blue-green algae in several popular recreation lakes, private ponds and decorative fountains. In the Summer of 2016 and 2017, the Sonic Plus water treatment system was placed in operation at the outlet of Lake Crystal. Below are the before and after photos of Minneopa Falls, which is approximately 12 miles downstream from the outlet of Lake Crystal. Note, the reduction of blue-green algae and the improved water clarity of the Minnopea Falls during the Sonic Plus operation period. 2016 Crystal Lake Recap and Minneopa Falls Historically Impaired Water, Minneopa Falls Pre-Sonic Plus Water Treatment System 2014 Lake Crystal Outlet Restored Water Quality, Minneopa Falls Post-Sonic Plus Water Treatment Project 2016-2017 in Lake Crystal Outlet Today our surface water restoration work is expanding. The implementation and application of this system continues to show positive results for multiple water quality parameters with direct evidence of suppression of cynobacteria levels and improvement in desired oxygen levels. The positive results of suppression of bacteria levels and improved oxygen levels also appears to effect: a reduction of invasive species, regeneration of native plants, increase in the population of desired game fish. Continued testing seems to confirm other water quality and environmental benefits from using this groundbreaking technology.

Winter's the Best Season to Plan your Site Redevelopment's Environmental Work Winter’s a great time to consider your next redevelopment project, because there’s time to assess and design, obtain approvals and permits, get a grant and be first to hit the ground. Here are tips on what to plan for. ​ ​ ​ Vapor Intrusion in Commercial Property Acquisition and Development Savvy leaders and developers are familiar with performing environmental due diligence as part of acquiring commercial property, and the industry standard for due diligence is the Phase I Environmental Site Assessment (ESA). ​ ​ Brownfield Redevelopment has Risks - but also has Business Rewards From approximately 1988 to 1998, businesses that owned or operated petroleum underground storage tanks (USTs) were required to remove and/or upgrade their old tank systems to prevent environmental releases. ​ ​ Preliminary Assessments are Required to Address Renovation or Demolition Project Hazards If you’re planning to renovate or demolish a commercial or residential structure, specific preliminary assessments must be conducted to protect occupants and contractors - and protect you from personal liability. The three primary environmental building inspections include asbestos, lead-based paint and regulated waste. ​ Evaluate Key Criteria before Redeveloping a Brownfield Site In previous Duluthian “Environment” articles, I’ve explained why brownfield properties can be a benefit to developers looking for their next project. This articles focuses on evaluating a project or property to determine if the fit is right for your plans. ​ The Rehabilitation of a River The Knife River, about a 19-mile drive up the North Shore from Duluth, once held one of the largest populations of naturally-reproducing steelhead in the Great Lakes. However, since the early 1970s, the Knife River’s steelhead population has experienced a dramatic decline. One of the reasons for this decline is habitat loss. ​ Back to the top Back to the top Back to the top Back to the top Back to the top Back to the top

  • Site Investigation and Remediation | Environmental Troubleshooters MN

    Site Investigation and Remediation Site Investigation Remediation Site Investigation Environmental Troubleshooters Inc. has a team of environmental scientists, geologists, and environmental professionals who have extensive experience designing work plans to investigate the release of hazardous chemicals and petroleum product. Our work plans determine the sampling strategy and drilling location/depth to adequately identify and delineate the magnitude and extent of a release. Our sampling strategies are based on our previous investigation knowledge and experience and we follow EPA requirements or state-specific guidance documents. Once a work plan is approved, we clear public and private utilities and advance soil borings, soil gas borings, sub-slab vapor points, test pits and/or utilize other investigative technologies (e.g. LIF borings, magnetometer surveys, etc.). Our standard soil sampling strategy includes collection of continuous sample cores to ensure no soil horizon is missed, and the use of dual-tube push probe sampling to provide accurate, discrete samples. ET personnel also have experience overseeing rotosonic, mud rotary, air rotary and bedrock coring drilling techniques. Borehole soil samples are typically collected at the highest photoionization detector (PID) value, highest x-ray fluorimeter (XRF) value, ground water table and/or bottom of the boring. Borehole water samples are typically collected using temporary wells to allow for sufficient ground water recharge providing adequate water volume for sample collection. Should permanent monitoring well be necessary, ET personnel install the wells according to state code with screened intervals in the saturated zone and adequate screen length to account for water table fluctuation when investigating petroleum or most-dissolved phase contaminants in shallow, unconfined aquifers. Deeper monitoring wells designed to assess dense non-aqueous phase liquids (DNAPL) are installed with submerged screens. ET follows strict boring and monitoring well decontamination procedures to ensure no cross-contamination exists during drilling and sample collection. Hollow Stem Auger Drilling in a Tank Containment Remediation When a leak or spill has occurred and cleanup is necessary, we have remediation experience to select the appropriate site-specific cleanup technology. For complex projects, we thoroughly evaluate site parameters and conduct feasibility studies to develop multiple remediation options based on technical and budgetary constraints. This allows you to select the remedial option to meet your needs. ET personnel have extensive experience with the most common remediation options which typically include excavation and/or vacuum pump truck extraction of fuel and contaminated groundwater. Excavation may be required to address recent leaks/spills, during tank removal, and/or to address surface contamination which poses a direct contact and runoff risk. Soil disposal options include composting/biopiling, thermal treatment, asphalt batch incorporation, landspreading/land treatment, stabilization, and landfilling. ET projects have included complex excavations near utility lines, building footings and within buildings. With the more recent establishment of vapor intrusion (VI) standards for residential and industrial/commercial buildings, the requirement for vapor mitigation in these structures is becoming more common. ET is a licensed vapor mitigation contractor and ET personnel have extensive experience installing effective sub-slab vapor mitigation systems. Suction pits are drilled through the slab floor and a vacuum is applied initially with a shop vac. Vacuum field extension is measured using a micromanometer and vapor pins installed through the slab in strategic locations. Permanent vacuum lines are then installed and connected to a radon-type blower. In some cases, remedial systems are the most effective cleanup technology. We have experience with multi-phase extraction, soil vapor extraction, air sparging, bioventing, and other remedial system technologies. ET has designed, installed and successfully operated remedial systems targeting petroleum and chlorinated solvent releases. To ensure we have selected the best approach we optimize our system design using advanced computer modeling and pilot testing. ET personnel have installed/operated remedial systems for emergency response work and standard remedial work at gas stations, industrial and commercial sites, and are familiar with permitting, air emission and water discharge requirements. Environmental Troubleshooters Inc. also has extensive remedial experience with bioremediation via compound injection, which may include oxygen-release compounds, emulsified vegetable oils, bacteria inocculum, and various other solutions. In some cases, bioremediation may involve application of bacteria directly to spill areas. ET personnel have also conducted projects where multiple injection points over large industrial and military projects are required, with use of temporary tanks, dosing pumps and injection via push probe and other technologies.

Our ESAs are conducted in accordance with American Society for Testing and Materials (ASTM) standards and EPA's All Appropriate Inquiry Requirements. Supplemental services required under Housing and Urban Development (HUD) and the Small Business Administration (SBA) are also available. When a Phase I ESA identifies recognized environmental conditions (RECs), data gaps or business environmental risks at a site, ET performs a Phase II ESA to assess for the presence of contaminants, including the collection of soil, groundwater and soil vapor to determine the extent and to quantify the risk to the property and occupants. Burn Pit Brownfields Redevelopment and Clean Up Grant Assistance Brownfields are properties that are contaminated from historic uses. There are unique challenges to redeveloping brownfield sites, including reducing unknowns, cost control, and complying with environmental regulations while running an efficient construction project. State and federal grant funding may be available to assist with redevelopment, including vapor mitigation and contaminated soil management. ET has worked with municipalities and developers for over a decade to assist clients with obtaining state and federal brownfields grants. These grants benefit the community by redeveloping underutilized properties, reducing neighborhood blight, increasing property values and tax base and stimulating redevelopment to the surrounding area. Gander Mountain Brownfields Redevelopment - Before Site Closure Negotiations and Regulatory Assurances Regulatory protections are available for buyers, developers and lenders associated with brownfield properties. If these parties follow the proper due diligence path, they can be granted voluntary party status and receive regulatory No Further Action Letters, No Association Determinations and/or Off-site Source Determinations. These assurances program provide developers with a regulatory path to move forward, banks confidence to loan money and collateralize the site, and realtors the ability to market and sell the site. Many leak or spill sites that have been previously closed still remain contaminated. This residual site contamination may result in a decrease to the value of the property. ET routinely assists clients with determining the property value reductions at sites due to the presence of contamination.
