Various federal and state guidance documents and rules are rapidly evolving on the subject of vapor intrusion. Discover what experts are saying about the topic when under the scrutiny of discovery and litigation, and how are courts reacting.

Given the existence of non-binding U.S. EPA guidance, complimented by diverse vapor intrusion regulations and policy in the states, how do property owners, regulated parties, plaintiffs, defendants, attorneys, environmental consultants, and others go about evaluating and making decisions regarding vapor intrusion?

The answer is the sa... More →

More than 44 million Americans depend on a private well for their water. Drought conditions and overuse have caused ground water levels to drop all over the country. If a homeowner has a well that is not deep enough, they may have to drill a deeper one or find water elsewhere, an expensive and troubling proposition.

The Journal Nature recently reported that globally, groundwater sources are stressed at 3.5 times their capacity to produce, and the New York Times reported that wells are running dry around the U.S. Midwest. Meanwhile, most people with wells have no idea if the water in... More →

WelNet monitors changes in groundwater systems that are caused by pumping, agricultural methods, and local precipitation. The impact of pumping and agriculture is accelerating and pressure on the groundwater resource is intensifying. Hydrogeologists need data to confirm these changes, and make recommendations to adapt to them. While some exciting new information sources, like NASA GRACE satellite program, have become available, data resolution, and therefore local response, remains low.

In groundwater models, the software estimates that groundwater decision-makers rely on, but they ... More →

Michael R. Shultz blogs that outcropping ancient river deposits illustrates the primary challenge to successful groundwater remediation ... stratigraphic heterogeneity. Encountering heterogeneity in the form of stratigraphic layering is common at every groundwater remediation site where sedimentary aquifers are impacted.

Unfortunately, so too is the common practice of layer labeling and counting in which it is assumed that the first sand encountered when drilling (i.e., the A sand), is a homogeneous, isotropic layer, followed by the next layer, etc. This almost never the case, a... More →

Yamaha has announced the inaugural commercial operation of its RMAX remotely piloted helicopter for agriculture spraying service in the U.S. The RMAX flight was completed in California for Napa-based Silverado Farming Company, a vineyard management company. During its debut the RMAX applied a fungicide for preventative control of powdery mildew, one of the most common fungal diseases affecting grapes and many other crops.

For Yamaha, the U.S. debut of RMAX commercial services for the agricultural industry marks the culmination of several years working with the FAA to receive appropr... More →

Seyed Mahmood VaeziNejad, et al., report that drought and groundwater withdrawal in recent years has caused numerous problems such as subsidence due to falling of subsurface water table, the reduction of water quality, etc. in cities across the world. This research is a case study that deals with harmful effects of subsurface water withdrawal in the city of Kerman and with the practical monitoring of the subsidence that makes the prediction of land subsidence possible.

The artificial neural network has been used for modeling the monitored results and prediction of future subsidence... More →
