System development charges (SDCs), otherwise known as impact fees, are difficult for most small systems to determine. This SDC Calculator was developed with funding from MTAC, and predicts the unit cost of adding new development to an existing water system. The Calculator gives users the option of two general methodologies when determining the cost impact of new users.
Built in Microsoft Excel, the SDC calculator also easily imports data from your capital asset inventory database (developed in CAPFinance). This data is especially important when calculating SDCs using the Equity Buy-In methodology
Poster: Chemical Factors Affecting Arsenic Removal at Water Treatment Plants.
The Illinois State Water Surveys' Center for Groundwater Science web site provides a good overview of Arsenic in Illinois Groundwater.
The USEPA is proposing a rule to regulate the disinfection of ground water and other issues to assure protection of the public health in ground water systems. The Proposed Ground Water Rule is currently under review and could be issued this year.
MTAC sponsored a project seeking to improve arsenic removal efficiency with minimal equipment and chemical expense. Development of Low Cost Treatment Options for Arsenic Removal in Water Treatment Facilities found that in an Illinois groundwater, they were able to reduce the total arsenic from about 40 mg/L to less than 5 mg/L in batch, laboratory flow, and pilot-scale flow experiments. The estimated chemical costs for treatment totaled about $0.07/thousand gallons.
EPA 816-R-99-006 is a comprehensive review of the occurrence of various contaminants regulated under the Safe Drinking Water Act found in public water supplies.
The USEPA has made minor revisions to the Lead and Copper. The revision primarily streamline compliance procedures and clarify requirements. The Lead and Copper Rule Minor Revisions (LCRMR) do not change the action limits of 1.3 mg/L for Copper or 0.015 mg/L for Lead.
Storm Event and Continuous Modeling of an Illinois Watershed to Evaluate Surface Water Supplies Based on recent reviews of leading watershed-scale hydrologic and nonpoint-source pollution models, the long-term continuous model SWAT was selected to enhance with storm event simulation algorithms from a storm event model. It will be used as a source-water protection and assessment tool for small public water supply systems.

MTAC Quick Facts highlight results of Competitive Grant Projects.
MTAC, in cooperation with the National Drinking Water Clearinghouse, has developed Fact Sheet handouts to present some of the results of completed projects in an abbreviated format that is easily downloaded for future reference. MTAC also produces their own Fact Sheets for other projects. These sheets provide a summary of the important findings and recommendations of the work.

MTAC is pleased to announce the release of Drought Planning for Small Community Water Systems. This report details existing resources available to assist small communities in planning for extended droughts, and includes recommendations for conducting drought-sensitivity studies for small community water systems in the MTAC region. The report provides a framework for improving drought preparedness planning for small community water systems in the MTAC region. This plan also may be useful in drought preparedness planning in other regions.
This analysis of county-level, public-supply water use in six Midwestern states provides useful insights into the relationship between water use and those factors that are most likely to predict or explain water use. It also provides a perspective on the challenges that face water system managers and regional officials in planning to meet future water system infrastructure needs in the region. Countywide Projections of Community Water Supply Needs in the Midwest This summary reviews the water-use projections and related findings of the study, and makes several recommendations for actions that may improve water use forcasting and infrastructure planning for drinking water systems.
Past MTAC Annual Reports are on the web. Download a copy and read it to learn about what we have been doing.
The Final Reports for a number of MTAC sponsored research projects are available on-line. Completed projects include such diverse topics as drought planning, corrosion, arsenic, financial benchmarking, and source water protection planning.
