The 1,4-dioxane contamination is not a new problem. From 1966 until 1986, Gelman Sciences (later Pall Corporation and now Danaher) used 1,4-dioxane in their manufacturing process at their facility on Wagner Road. Gelman's wastewater, containing 1,4-dioxane, was disposed of onsite during that time. In 1985, 1,4-dioxane was discovered in residential drinking water wells in the area. Unfortunately, 1,4-dioxane does not break down quickly in water and large plume still exists underground in the soil and water, even after all this time.
There is an area in Washtenaw County where a 1,4-dioxane plume is underground. A plume is a volume of contaminated groundwater that extends downward and outward from a source. The 1,4-dioxane plume is moving through groundwater; the direction and speed of the contamination plume is affected by the local geology. The plume area includes parts of Scio Township and western Ann Arbor. This contamination is a concern because wells near the area draw groundwater for use in homes and businesses.
There are currently over 250 monitoring wells located in and around the plume that are used to track water levels and 1,4-dioxane concentrations. If you have one or more monitoring wells on your property and have questions about the access agreement(s), please contact Jim Brode at (269) 993-7585.
The Michigan Department of Environment, Great Lakes and Energy (EGLE) also collect annual surface water samples from the plume area. Surface water sampling locations include the Sister Lakes, Smith Ponds, unnamed tributary of Honey Creek, Honey Creek, the Huron River at Maple Rd, Little Lake and the West Park pond. For more information on surface water sampling please contact the EGLE Remediation and Redevelopment Division's Jackson District Office at (517) 780-7690.
The Michigan Department of Environment, Great Lakes and Energy (ELGE) contracts with the Washtenaw County Health Department to monitor drinking water wells along the plume edges. Approximately 375 drinking water wells have been sampled since 2014.
The Plume-Surface Interaction (PSI) Project is advancing both modeling and testing capabilities to understand exactly how rocket exhaust plumes affect a planetary landing site. This advanced modeling will help engineers evaluate the risks of various plumes on planetary surfaces, which will help them more accurately design landers for particular locations.
Safe and efficient landings often require the use of rocket engines to decelerate the landers to a soft touchdown on the surface. When the rocket plume of a lander interacts with planetary regolith, the landing site can be affected in several ways. The plume exhaust can erode the planetary surface, which can destabilize the lander. Another danger landers face is surface particles that are ejected from the area. These tiny particles can find their way inside a lander and damage important instrumentation and obscure visibility for radar and other optical ranging systems. Better understanding these types of risks will help engineers design landers to accommodate potentially risky situations.
The PSI project is advancing predictive modeling and simulation capabilities to understand the physics associated with the exhaust plume, erosion, and ejected particles from a landing site. This capability to simulate how a plume will affect a landing site will help engineers protect landers by more accurately evaluating the risks of targeted landing sites. With a better understanding of various landing sites, engineers will be able to tailor lander designs for particular sites, which will limit overdesigning and reduce building costs.
Introduction: The COVID-19 pandemic requires us all to re-evaluate aesthetic practices to ensure optimal patient safety during elective procedures. Specifically, energy-based devices and lasers require special consideration, as they may emit plume which has been shown to contain tissue debris and aerosolized biological materials. Prior studies have shown transmission of viruses and bacteria via plume (i.e., HIV and papillomavirus). The purpose of this study was to evaluate plume characteristics of the Er:YAG resurfacing laser (Sciton; Palo Alto, CA) and compare it to the Morpheus8 fractional radiofrequency device (InMode; Lake Forest, CA).
Conclusion: Re-evaluation of the plume effect from aesthetic devices has become important during the COVID-19 pandemic. Further studies are required to characterize viability of COVID-19 viability and transmissibility in plume specimens. Based on this pilot study, we recommend that devices that generate little to no plume such as fractional radiofrequency devices be used in Phase I reopening of practice while devices that generate a visible plume such as Er:YAG laser resurfacing devices be avoided and only used with appropriate personal protective equipment in addition to a smoke evacuator in Phase IV reopening.
Please note MISR Plume Height Project data is now accessed via the MISR Enhanced Research and Lookup Interface (MERLIN), hosted by the NASA Atmospheric Science Data Center. This online tool provides new search, visualization and analysis capabilities beyond those that were available through the old MISR interface. Users are also able to download individual plume files as before.
As of mid-Dec 2023, El Niño conditions in the central-eastern equatorial Pacific remain strong with key oceanic and atmospheric variables consistent with an ongoing El Niño event. A CPC El Niño advisory remains in place for December 2023. Almost all the models in the IRI ENSO prediction plume forecast a continuation of the El Niño event during the rest of the boreal winter and spring of 2024, which rapidly weakens thereafter. ENSO-neutral conditions become the most likely category in Apr-Jun, of 2024, and remain so during the next two seasons of the forecast period. For Jul-Sep 2024, no single category stands out as dominant, with ENSO-neutral and La Niña being equally likely. By Aug-Oct 2024, La Niña becomes the most probable category, with a likelihood of 52%.
The latest set of ENSO prediction models from mid-December 2023 are now available in the IRI ENSO prediction plume. These are used to assess the probabilities of the three ENSO categories by using the average value of the NINO3.4 SST anomaly predictions from all models in the plume, equally weighted. A standard Gaussian error is imposed over that averaged forecast, with its width determined by an estimate of overall expected model skill for the season of the year and the lead time. Higher skill results in a relatively narrower error distribution, while low skill results in an error distribution with width approaching that of the historical observed distribution.
A caution regarding the model-based ENSO plume predictions released mid-month, is that factors such as known specific model biases and recent changes in the tropical Pacific that the models may have missed, are not considered. This approach is purely objective. Those issues are taken into account in the official outlooks, which are generated and issued early in the month by CPC, and which will include some human judgment in combination with the model guidance.
A purely objective ENSO probability forecast, based on regression, using as input the model predictions from the plume of dynamical and statistical forecasts shown in the ENSO Predictions Plume. Each of the forecasts is weighted equally. It is updated near or just after the middle of the month, using forecasts from the plume models that are run in the first half of the month. It does not use any human interpretation or judgment. This is updated on the third Thursday of the month.
The following interactive plot shows the model forecasts issued not only from the current month (as in the plot above),but also from the 21 months previous to this month. The observations are shown up to the most recently completed3-month period. The plots allow comparison of plumes from the previous start times, or examination of the forecastbehavior of a given model over time.
Hovering over any single model will highlight that particular model in the chart.
Clicking a particular model will hide/show that model in the chart.
At the bottom of the plot, you can select which models to show in the chart: all the models, the dynamical models only, or the statistical models only.
