Mapping High‐TDS Groundwater Near Impoundments Using Ground and Waterborne Towed Electromagnetics

open access: yesGroundwater, EarlyView.
Abstract Long‐term monitoring at landfills and impoundments containing coal combustion products (CCPs) or other industrial wastes is essential for detecting possible leachate releases to groundwater and mapping contamination plumes. This study evaluates a novel, non‐invasive geophysical approach—towed time‐domain electromagnetic (TEM) surveys—for non ...

Effect of Moderate Heat on TCE Reductive Dechlorination Rates in Groundwater

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Low‐temperature heating (in the mesophilic range of ~15 to 40 °C) of contaminated aquifers offers the prospect of increasing the rates for biotic and abiotic treatment of volatile organic compounds. Thermal In Situ Sustainable Remediation (TISR®) is one of the approaches available to implement low temperature heating.

The Productivity Effect of Public–Private Partnership

open access: yesThe Journal of Industrial Economics, EarlyView.
ABSTRACT Public–Private partnerships (PPPs) are often employed by public authorities to deliver infrastructure and public services through contracts bundling construction, operation, and maintenance over extended periods. Using a novel dataset covering the universe of Italian district heating plants (DHs) from 2007 to 2014, I show that PPP improves ...

Vertical profiling of shock attenuation at the Rochechouart impact structure, France

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Rochechouart, south‐west France, is a complex impact structure. Here, we present the first report of shock barometry of quartz from what are likely parautochthonous basement units at depth, based on samples from the 2017 C.I.R.I.R drilling campaign. The crystallographic orientations of 725 sets of PDFs in 512 quartz grains in samples from four

A geophysical investigation of the Roter Kamm impact crater, Namibia

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The Roter Kamm impact crater is located in the southern Namib Desert. The crater has a diameter of 2.5 km and belongs to the category of simple, bowl‐shaped impact craters, with an elevated rim of fractured target rock. The crater's interior is completely buried beneath sediments, preventing extensive surface investigations of the bedrock ...
