Establishing a site-specific groundwater monitoring protocol sensitive to changes in the groundwater chemistry related to potential leakage and also sensitive to natural variability will be imperative for developing cost-effective and robust testing and monitoring plans.
In CCUS projects, a site-specific testing and monitoring plan is mandatory to ensure the protection of underground sources of drinking water (USDWs) from Class VI injection well practices. As these projects have long durations with multiple phases, it is imperative for the groundwater monitoring program to be cost-effective with a robust sensitivity to detect any leakage.
Previously demonstrated changes in pH, carbonate chemistry, and certain trace elements (i.e., those that form strong-complexing anions) are geochemical indicators of initial CO2 leakage in relatively dilute aquifers. In this case study, SCS Engineers examine the sensitivity of dilute aquifer chemistry (major and minor cations and anions) to the leakage of CO2 and brines from the injection formation. We use an inverse thermodynamic modeling approach to simulate the effect of the progressive intrusion of CO2 and brines from the injection zone on the geochemical composition of the overlying dilute aquifer waters. From this, we can infer which geochemical parameters are most likely to be affected by the potential intrusion of CO2 and brines.

EPA permit requirements for Class VI injection wells explicitly include incorporating a Testing and Monitoring Plan to optimize protection of USDWs – Underground Sources of Drinking Water. The regulatory requirement is for periodic monitoring of groundwater quality above the confining zone that may result from injection fluid movement through the confining zone. Testing and monitoring plans usually implement an antidegradation strategy. Take sufficient background data to characterize the statistical distributions of groundwater quality parameters before operation. Then the same water quality parameters are sampled periodically during and after injection and compared to the background. Any statistically significant increases over the background are investigated as a possible result of injectate migration above the confining zone.
To make the detection monitoring program more robust, there is a tendency to increase the number of well/parameter pairs in the monitoring network. This is done by adding additional wells to decrease well spacing and by adding monitoring parameters to make sure that nothing gets missed. Paradoxically, this tendency decreases the statistical power of the groundwater monitoring network by increasing the sitewide false positive rate (i.e., the number of false positive detections increases, often to an unreasonable degree). Each apparent statistically significant increase involves a costly investigation with greatly increased complexity. In this talk, we examine the sitewide false positive rate for sitewide groundwater monitoring networks and its relationship to the number of well/parameter pairs and discuss how hydrologic and geochemical knowledge and characterization can be used to build a more robust and cost-effective groundwater monitoring plan that is protective of USDWs near Class VI injection wells.

Cutting food loss and waste is widely recognized as one of the most powerful levers we have to address climate change and preserve our natural resources. In the United States alone, surplus food accounts for 4% of our greenhouse gas emissions, 14% of all freshwater use, and 18% of all cropland use. We’re wasting precious resources to produce and ship food only to have it end up in a landfill or rot in a field. [ReFED]
These are key action areas where the food system can focus its efforts over the next decade to prevent, rescue, and recycle food at risk of becoming waste. Strengthening food rescue and recycling anything remaining into compost or anaerobic digestion facilities creates beneficial by-products.
The USDA offers grants of up to $300,000 to composting and food waste reduction pilot projects benefiting community food waste and production programs.
Eligible projects can be in rural, urban, and suburban communities. The application deadline is fast approaching on September 1, 2022. USDA anticipates making selections by October 30, 2022, and executing the grant awards by February 8, 2023.
Visit SCS Engineers to learn more about this grant opportunity, check program qualifications, and sign up for free consulting supporting communities interested in this unique USDA grant program.

Hold The Plastic, Please! Consumers who purchase restaurant food for home delivery don’t often require plastic straws, disposable plastic cutlery, and single-use plastic packets of ketchup, soy sauce, and mustard that come along with it. Many restaurants and food delivery services have smartened up and made these optional choices. So, if you want a little less plastic with your food, let your local restaurants know. It will save them and you money and works toward reducing the amount of plastic floating around our oceans.
Beyond Plastics recently published a free, downloadable guide called “Hold The Plastic, Please – A Restaurant’s Guide To Reducing Plastic.” The guide offers restaurant owners detailed, practical, and inspiring advice on how to reduce the use of plastic in their operations and how to effectively convey those changes to customers, reporters, and the general public.
Beyond Plastics is a nationwide project based at Bennington College in Bennington, Vermont, whose mission is to end plastic pollution by being a catalyst for change. It takes changes at every level of our economy and civil life to stem the tide of plastic pollution. Individuals can take small actions in their everyday lives to be part of a growing movement to make a difference. Corporations can initiate changes in their purchasing and packaging habits; governments can impose bans and adopt laws that require extended producer responsibility.
Many landfills are still using hand-held monitoring of methane “hot spots” for compliance purposes while relying on models to estimate LFG emissions. Although technological developments in optical remote sensing and other methods offer significant improvements to measuring actual surface emissions from landfills, no single technology or method has risen to the top of the scientific hierarchy, gained universal acceptance, and achieved regulatory approval. Clearly, the technological advances provide more comprehensive methods for measuring methane concentration, identifying methane hot spots and leaks, and providing better coverage of the entire landfill surface. However, some technology falls short in their ability to provide accurate, consistent, and repeatable methane flux or emissions measurements.
As monitoring technology evolves, so have the various ways SCS takes measurements, from source level, drones, and high-altitude aircraft, to satellites. This paper presented at A&WMA by Patrick Sullivan and Raymond Huff summarises and provides details on the following methods:
• First order decay (FOD) modeling for landfills without active LFG collection systems.
• Non-FOD modeling for landfills without active LFG collection systems.
• FOD modeling with measured LFG collection.
• Non-FOD models with various site-specific data input.
• Measured LFG collection with estimated collection efficiency.
• Surface emission monitoring for compliance purposes.
• Ground-based or low-altitude imaging for concentration or hot spot measurement.
• Satellite and aerial imaging for concentration or hot spot measurement.
• Flux chamber testing.
• Ground-level plume measurement.
• Micrometeorology.
• Stationary path measurement.
• Reverse air dispersion modeling.
• Tracer studies.
• Low or high-altitude imaging.
• Hybrid methods.
The 2022 NAAMC, sponsored by US EPA in conjunction with the Association of Air Pollution Control Agencies and the National Association of Clean Air Agencies, is a must-attend event for federal, state, local, and tribal air pollution organizations involved with operating, planning, or managing air monitoring networks and reporting data to AQS, and AIRNOW.
In addition to essential training on air monitoring topics, these SCS Engineers professionals will present the following sessions:
Sergio Valenzuela – Quantifying Salton Sea’s Harmful PM During High Wind Events
This study analyzes the correlated TEOM data (centric to high wind event days) and PQ200 data in comparison with TEOM data during “clear” (≤5-mph) days to determine the concentration levels of PM created during high wind events. Also, the incorporation of wind rose diagrams, created using wind speed/direction data collected at meteorological towers, aids in understanding varying PM concentrations relative to their deployment site properties. This study provides an essential tool for understanding the amount of exposure that neighboring communities are experiencing during high wind events and how IID’s implemented mitigation efforts will look moving forward.

Jose Landeros – Air Monitoring in Mexicali, Mexico. The Evolution of Air Pollution Monitoring in a Border City.
Advancements in technology have influenced the way air pollution is measured and how air pollution data is received, shared, and acted upon by stakeholders. Using Mexicali, México as an example, this presentation will review the evolution of the air pollution monitoring technologies used to measure and inform stakeholder actions. Stakeholders now can access real-time air quality data from platforms that integrate information from low-cost sensors and regulatory sites. The evolution of technology for measuring and presenting data has been remarkable – from large, manual, analog equipment to small, automated, digital equipment with communication systems that allow for real-time data access.
