AMS

In this episode of AMS Talks, industry consultant and special guest host Nadia Abboud sits down with Rocio Flores, Water Quality Engineer for Golden State Water Company. Rocio shares valuable insights into how Golden State Water has been tackling the challenge of managing a groundwater source with selenium concentrations that exceed the Maximum Contaminant Level (MCL) for their Edna Road System. Watch this interview for an insightful look into managing heavy metal exceedances in areas with limited water sources and the value of investing in real-time selenium monitoring to support the treatment process.

In this episode of AMS Talks, industry consultant and special guest host Nadia Abboud engages in a detailed conversation with Steve Mungari, Business Development Manager for AMS, about the critical issue of hexavalent chromium (Cr6) treatment planning and compliance. The discussion centers around the initiatives Steve is spearheading at AMS to support the nearly 500 sites across California that need to assess, determine, and implement compliance plans to meet the 10 ppb MCL regulation for Cr6. Watch this insightful interview to learn how AMS is positioned to aid utilities in achieving Cr6 compliance.

As a cost-effective and efficient solution for municipal and industrial users, SafeGuard™ H2O removes inorganics, organics, and metals from water and wastewater. This revolutionary system reduces the need for bulk toxic chemicals.  The fully automated SafeGuard™ H2O technology produces a non-toxic ferrous reagent onsite and on demand using an in-situ electrolytic generator and a certified precursor. It operates on low power electricity from renewable sources.

Cities across California must prioritize the implementation of Cr6 treatment solutions while protecting their investment. Therefore, as cities set out to meet today’s 10-ppb MCL, they must consider the MCL of the future and adopt the right Cr6 treatment approach that can cost-effectively comply with a more stringent regulatory limit. SafeGuard™ H2O provides a solution that ensures safety and confidence for cities. With SafeGuard™ H2O, cities can pursue a water blending strategy where appropriate and be assured of sustainable compliance if the State decides to lower the MCL.

The SafeGuard™ H2O Cr6 removal system from AMS is an affordable and reliable hexavalent chromium (Cr6) remediation solution that complies with California’s new 10-ppb MCL regulation. This NSF-approved Reduction/Coagulation/Filtration system is a designated Best Availability Technology (BAT) for Cr6 removal. With its rapid deployability and competitive financing terms, SafeGuard™ H2O makes demonstrating Cr6 removal easier and more accessible than ever before.

In the latest episode of AMS Talks, Abigail Cantor, P.E., Chemical Engineer at Process Research Solutions LLC. discusses a collaboration project with Madison Water Utility to evaluate real-time monitoring of lead and copper in drinking water. This project is particularly timely given the recent EPA proposal to update regulations for reducing lead and copper exposure through drinking water. The proposed regulation will rely more heavily on using lead and copper monitoring and testing apparatuses that have historically lacked real-time data on water corrosivity, crucial for managing fluctuating lead and copper levels in water. Cantor outlines an innovative testing apparatus approach that mimics residential plumbing and incorporates automated online AMS MetalGuard™  lead and copper monitors to provide more frequent and real-time analysis. Utilities looking to adopt a cutting-edge monitoring and testing approach for lead and copper in drinking water systems will not want to miss this interview.

The fully automated SafeGuard™ H2O technology produces a non-toxic stannous reagent onsite and on demand using an in-situ electrolytic generator and a certified precursor. As a cost-effective and efficient solution for municipal and industrial users, SafeGuard™ H2O removes Cr(VI), Fe, H2S, Hg, Pb, and Se from water and wastewater. It also acts as an antibiofilm, antimicrobial reagent for produced water, and as a corrosion inhibitor in distribution networks and cooling systems.

The Lead and Copper Rule Improvements (LCRI) regulation will rely more heavily on using lead and copper testing and monitoring apparatuses. These apparatuses have issues around sampling constraints and lack real-time data on water corrosivity to anticipate the risk of lead/copper corrosion before it happens in homes/schools/daycares. This is where the benefit of real-time lead and copper monitoring in drinking water systems can significantly contribute to a water system’s compliance with the proposed lead and copper action levels outlined in the LCRI. The automatic, unattended online MetalGuard™ analyzer from AMS provides high-frequency, timely, and accurate predictive data to stakeholders on their exposure to lead or copper contamination risks.

A SafeGuard™ H2O demonstration system with a capacity of 3 gpm (150 mL/minute) was installed onsite for testing at the City of Banning’s Facility Well C2 from June-September 2022. The scope of this demonstration focused on the safe, reliable reduction of Cr6 to Cr3 using SafeGuard™ H2O electrogenerated stannous reagent.  The demonstration validated the effectiveness of the SafeGuard™ H2O technology to treat Cr6 and Cr(T) below 10 ppb, granting it conditional acceptance from the California SWRCB Division of Drinking Water for use of the technology by public drinking water systems to treat Cr6 contamination.

A recent demonstration at the City of Banning, California, validated the effectiveness of the AMS SafeGuard™ H2O technology to treat Cr6 and Cr(T) below 10 ppb, granting it conditional acceptance from the California SWRCB Division of Drinking Water for use of the technology by public drinking water systems to treat Cr6 contamination. SafeGuard™ H2O generates a non-toxic stannous reagent on demand via an electrolytic process, offering utilities of all sizes an affordable, effective and sustainable Cr6 remediation solution.
