The optimal design of groundwater quality monitoring networks under conditions of uncertainty
The design of a monitoring network to provide initial detection of groundwater contamination at a waste disposal facility is complicated by uncertainty in both the characterization of the subsurface and the nature of the contaminant source. In addition, monitoring network design requires the …

Augmenting Indiana's Groundwater Level Monitoring Network: Optimal Siting of Additional Wells to Address Spatial and Categorical Sampling Gaps
Groundwater monitoring networks are subject to change by budgetary actions and stakeholder initiatives that result in wells being abandoned or added. A strategy for network design is presented that addresses the latter situation. It was developed in response to consensus in the state of Indiana …

Development and implementation of a microresonator impactor for atmospheric particulate sensing
… nodes as part of ambient or personal air quality monitoring networks. As a result, optical particle counters (OPCs) have risen in popularity given their ability to consistently size and count individual particles. OPCs have limitations, however, in their inability to detect ultrafine particles …
