IDEM RiverWatch Program

Issue

No data has been collected on a segment of Richland Creek in northeastern Greene County since 2001. Richland Creek has been identified as a PCB-contaminated stream.Since the last sampling, conducted by IDEM personnel, numerous land-use changes have occurred upstream from the monitoring point. The program affords the opportunity to collect new data and provide a mentoring opportunity for interested high school students with access to the stream at the designated monitoring location.

Objective

Collect pertinent data for the IDEM volunteer stream monitoring program known as RiverWatch. Students will be trained to (1) collect water quality data consisting of: temperature, conductivity, pH, redox, dissolved oxygen, biochemical oxygen demand (BOD), turbidity, nitrate, phosphate; (2) flow estimation of stream using cross-section and velocity method; (3) record physical description of stream and bank up to 200 ft above monitoring point, describing stream bed, riparian zone, and sinuosity of stream; (4) collection and identification of macroinvertebrates living in stream at monitoring site, (5) test for total coliform and E. coli bacteria in stream. Student activity will be monitored and assisted as needed. Students will enter data into online forms at IDEM website.Monitoring activity will be conducted once each season for one year for a total of 4 monitoring days.

Planning, coordination, and training associated with lead sampling activities in schools

Issue

The state of Indiana has an objective to test the drinking water of all public school buildings for the presence of lead, to interested schools and school districts. Because lead can enter the drinking?water distribution system through the corrosion of a variety of plumbing materials (pipes, fittings, fixtures, solder, and flux), it is important to identify potential problems at the fixture level under normal water?use conditions (i.e., when schools are in session). A secondary issue is the need to characterize and understand the water chemistry that feeds the water?distribution system of schools to evaluate the potential for pipe or fixture corrosivity from that water. Current methods to identify problems are implemented through the Lead and Copper Rule (U.S. Environmental Protection Agency, (https://www.epa.gov/dwreginfo/lead?and?copper?rule), which provides guidance to systems that find lead exceedances in their lead analyses, but does not offer any method to predict systems that might develop a problem over time from the water supply itself.

Objective

The objective is to provide comprehensive planning, coordination, and sampling services for all schools that express interest and participate in the Indiana school water sampling program.

Spatial analysis of significant water withdrawal facilities in Indiana

Issue

The issue of water-resources planning is coming to the forefront in Indiana. Early reconnaissance studies have indicated that incomplete or inaccurate databases might inhibit studies that rely on those data. Therefore, examination of existing databases and creation of new, targeted, and relevant databases related to water resources are needed in Indiana.

Objective

This project will support the larger effort of improving the data accuracy in databases important to water resources planning in Indiana.

Unconsolidated sediment (soil) core description database forms - Core-nucopia

Issue

A great deal of effort is put into describing soil core for various geologic investigations but recording descriptors on paper forms and then converting that paper data to an electronic format for further processing is cumbersome and rarely accomplished.

Unsaturated-zone hydrology of glacial hydrogeologic settings in Indiana

Issue

Understanding water movement through the unsaturated zone is essential to maximizing agricultural productivity, minimizing flood impacts, limiting contaminant transport to aquifers, and elucidating potential climate-change impacts on Indiana’s water resources.

Objective

Unsaturated zone data from monitoring sites in eight unique glacial hydrogeologic settings are processed and analyzed to better understand rates of water movement toward underlying aquifers and adjacent surface water bodies.
