AMS Delivers an Affordable Treatment Solution for Hexavalent Chromium Removal in California

Hexavalent chromium (Cr6) in drinking water is a controversial topic in California. More than 20 years after the film Erin Brockovich was released raising public awareness and concern about Cr6, high levels of the contaminant continue to pose a threat to the health of thousands of consumers. To meet the need for an affordable treatment system that eliminates Cr6 from drinking water supplies and removes the barrier to a lower regulatory limit for this carcinogen, AMS developed SafeGuard™ H2O. The technology ensures a safe and affordable treatment approach to meet the Cr6 public health goal of 0.02 ppb while saving California taxpayers millions of dollars. During a pilot demonstration at the City of Los Banos, Calif., AMS’ SafeGuard H2O Cr6 treatment system proved to reduce Cr6 to non-detect levels at an annual cost per household in small communities of less than $5 per day.

When Contamination Comes a Knockin’ — SafeGuard™ H2O to the Rescue

In the fight to keep water safe and affordable, there is only one technology for the job! SafeGuard™ H2O is a fully automated, on-demand, in-situ generator of stannous (reducing agent) and tin dioxide (adsorbent), coupled with online monitoring capability. SafeGuard H2O removes As, Cr(VI), Cu, Fe, Pb, and Mn from drinking water and As, Cr(VI), Hg & Se from wastewater; acts as corrosion inhibitor for lead pipes and cooling systems; adsorbs SO2, H2S from industrial emissions. Tin and electricity are the only consumables. There are no similar technologies to SafeGuard H2O that integrate a low life-time cost contaminant treatment system with real-time performance controls. With SafeGuard H2O, contaminants have met their match!

Los Banos, Calif. SafeGuard™ H2O Cr(VI) Treatment System Pilot Report

A SafeGuard™ H2O intelligent Cr(VI) remediation system demonstration unit with a treatment capacity of 10 gpm was installed with the City of Los Banos, California to evaluate the performance of the technology to treat Cr(VI) to non-detect levels (under 1 ppb) in unchlorinated well water.  SafeGuard H2O is an innovative technology based on a proprietary approach that generates on demand a stannous ion reagent in-situ via an electrolytic process. The pilot with Los Banos provided confirmation of the technology’s efficacy and third-party validation of the SafeGuard H2O system as a cost-effective alternative to traditional Cr(VI) treatment systems. Results are detailed.

The Global Industry Standard on Tailings Management

The Global Industry Standard on Tailings Management, published in August 2020 by The Global Tailings Review, provides a framework for safe tailings facility management while affording Operators flexibility as to how best to achieve this goal. The Standard strives to achieve the ultimate goal of zero harm to people and the environment with zero tolerance for human fatality.

AMS Installs SafeGuard™ H2O Cr(VI) Remediation Full-Scale Pilot in California

AMS installed a full-scale pilot of its SafeGuard™ H2O intelligent Cr(VI) remediation system in a Central Valley California Community. SafeGuard™ H2O is an innovative technology based on a proprietary approach that generates on demand a stannous ion reagent in-situ via an electrolytic process. The goal of the pilot is to demonstrate the system’s ability to effectively and affordably treat water with elevated Cr(VI) levels to non-detect levels (less than 2 ppb) by converting toxic Cr(VI) to insoluble nontoxic Cr (III), which then can be removed by filtration along with tin dioxide — the product of the conversion. The stannous generator system features automatic dosing and incorporates continuous, real-time monitoring of Cr(VI) levels at the influent and effluent to ensure optimal treatment and compliance with regulatory and operational targets 24/7/365. Through the onboard online analyzer the technology’s ability to effectively reduce Cr(VI) was seen immediately.

AMS Talks: The Environmental Impact of Abandoned Mines

In this episode of AMS Talks, Rick Bacon, CEO of AMS, and Marcie Demmy Bidwell, Executive Director for the Mountain Studies Institute in Colorado, discuss the environmental impact of abandoned mines and efforts to protect water quality. Colorado has roughly 23,000 abandoned mines. Because of the financial scale of this challenge and the existential threat posed by these mines to human health and the environment, Bacon and Bidwell discuss the importance of bringing together the voice of governments, mining companies, and technology solution providers to share ideas and work together toward a solution to this pressing issue.

Bringing Innovative and Affordable Solutions to a Costly and Complex Problem

AMS is committed to bringing intelligent water remediation solutions that can be fully controlled, monitored and optimized remotely, while ensuring that these systems are more accessible to a wider sector of the population through affordable financial models. As such, AMS has offered an official response to a white paper — “Economic Feasibility Analysis in Consideration of a Hexavalent Chromium MCL” — published by the California State Water Board (SWB), who is engaged in a process of consultation to determine at what level the regulatory limit for Cr(VI) should be set. AMS’ position on Cr(VI) regulation and comments to SWB are summarized in this technical brief.
