Regulations and Technical Guidance for Sealing Unused Water Wells and Boreholes
Abandoned wells can be found almost anywhere and can be well marked or can just be an empty hole, causing a dangerous trap for anyone that may be exploring. This document explains the sealing requirements for the different types of wells and boreholes that are regulated in Ohio and provides guidance to those that are not regulated.
Properly Sealing Unused Wells
Properly sealing a well has become more important in avoiding contamination in a variety of ways. While this is not an important factor in water usage, this can affect many aspects of our water supply.
Selecting and Sizing a Two-Stage Channel System in an Agriculture Landscape
Drainage construction has been developed to work with the natural flow of a ditch system. By identifying the problem and working through the data collected there a channel can be constructed to gain the best results.
Economics of Implementing Two-Stage Channels
Two-stage channels are an alternative design for the open channel system. The two-stage channel design is a more sustainable approach to surface drainage management. The construction of the new channel does show cost distribution but the cost breakdown does show increased conservation of the water resource.
Two-Stage Ditch Case Study: Cessna Creek – Warmbroad Ditch
Warmbroad ditch is a small, headwater tributary to Cessna Creek and Blanchard River. The channel was modified to increase storage capacity and reduce excess sedimentation, streamflow and nutrient loading.
Building Better Ditches
Drainage has been important to agriculture in the Great Lakes for a long time. Options for re-establishing flood plains have been developed to help create stable streams the can relieve erosion and flooding that a conventional ditch can cause.
Phosphorus Transport in Agricultural Subsurface Drainage a Review
Phosphorus loss from agriculture dense areas has been an important water quality issue for decades. Work has been conducted to better understand the magnitude and importance of transport and treatments to decrease the loads to surface waters.
Contributions of Systematic Tile Drainage to Watershed Scale Phosphorus Transport
The results of the tile-drained watersheds indicate the contributions of Phosphorus to the waterways. To meet nutrients reduction goals surface waters, adjusting nutrient reduction practices and implementing practices are the best opportunity to decrease phosphorus delivery to tile drainage.
Contribution of Tile Drains to Basin Discharge and Nitrogen Export in a Headwater Agricultural Watershed
Intensively cropped watersheds of the U.S. Midwest have been recognized as a key source of nitrogen in the Mississippi River Basin. Results of this study demonstrate the concentrations associated with tile drainage and the seasonal factors. The best management practices can be adjusted to help these watershed issues become less impactful to stream water quality.
