Public Perceptions of the Midwest’s Pavements - Wisconsin - Phase I (Winter Ride)

The Wisconsin Winter Ride Survey was designed to determine the extent to which drivers were tolerant of the rougher ride of pavements on rural two-lane highways in the winter. Survey objectives, as such, were centered around this primary question of winter ride tolerance. A telephone survey was conducted by the Wisconsin Survey Research Laboratory (WSRL), which added questions to its quarterly Wisconsin Opinion Poll for the data collection period of January 15 to March 15, 1997. A similar survey focusing only on the topic of winter driving on rural highways was conducted in Minnesota during the same period. Random digit dial samples were drawn for both states according to accepted sampling procedure. The survey data set provided by WSRL included 417 respondents. Conclusions derived from the Wisconsin Winter Ride Survey included the following. Overall, Wisconsin respondents were predominately tolerant of the pavement’s potentially rougher ride in winter. Three-fourths of the 173 respondents who had noticed a change in the pavement indicated that they were more tolerant of the rough ride in winter than they would be the rest of the year. The extent to which motorists noticed changes in the pavement was influenced by the driving and vehicle characteristics. Respondents who drove more frequently on rural two-lane highways and those driving trucks, full-size vans or sport utility vehicles were more 2 likely to notice changes. The latter finding suggests that differences in suspension and ride entered in for respondents driving cars versus those driving trucks. It follows, therefore, that noticing pavement changes generally increased as ratings of the vehicle’s ride quality declined

Use of landfarming to remediate soil contaminated by pesticides

Landfarming is a cost effective solution to remediating soil and groundwater that have been impacted by pesticides. This remediation technique is a safe, sound and ideal solution for agribusinesses that want to take care of the environment without going bankrupt. With the promulgation of legislation allowing landfarming of pesticide contaminated or impacted soils, Illinois is progressing to explore alternative remediation technologies. Andrews Environmental Engineering, Inc. (ABEl) has permitted and managed the majority of the pesticide landfarming projects since authority was granted to the Illinois Department of Agriculture (IDOA) in July, 1990 to review and authorize these projects. This publication discusses, reviews and summarizes case studies on eighteen pesticide landfarming projects undertaken by ABEl.HWRIC Project Number HWR-91-08
