1) Water Supply Well Construction Guidelines for Use in Developing Countries, Second Edition
Last 2 November I posted about the first edition of Water Supply Well Guidelines for Use in Developing Countries thusly:
A serious shout-out goes to Steve Schneider - friend, NGWA colleague, engineer,water well contractor, hydrophilanthropist - who has just finished his opus,Water Supply Well Guidelines for Use in Developing Countries.
As he promised then, here is the second edition:
Download WATER_SUPPLY_WELL_GUIDELINES-second_edition.PDF_CP
Steve has prepared this one-pager with a number of useful explanatory and other links. Note that there is a link directly to Steve's WWW site to download the guidelines; I had trouble downloading the document using the Safari browser.

I am proud to say that my main two professional societies, AWRA and NGWA, have endorsed and supported Steve's work. The Ann Campana Judge Foundation has contributed and is accepting donations to support the publication and translations of the guidelines. Donate here, and specify that the donations are for the well guidelines.
2) Well Construction Cost-Benefit Analysis - Report and Spreadsheet
Jaynie Whinnery, an OSU graduate student and volunteer with EWB-OSU, created an Excel spreadsheet to perform a CBA that considers the differences between properly and improperly constructed/maintained water wells.
From the abstract of Jaynie's report:
This report is an economic cost-benefit analysis that considers the differences between properly and inferiorly constructed and maintained groundwater wells in developing countries, using rural Kenya as a case study. Factors of influence include the lifespan of the well, the number of beneficiaries, project expenses, environmental and health consequences, and other economic factors. The results highlight the importance of the role of proper construction, operation, and maintenance in realizing the full benefits potential of a new water well. Even if inferior construction methods do not cause more serious issues, the typical reduction in lifespan means only 30 percent of the potential benefits are provided. With the prospect of groundwater contamination and aquifer damage, the benefits may even be reduced to zero. This paper argues that saving a few thousand dollars up front, as tempting at it may be, is not worth this risk. Well construction approaches that provide cost savings should be carefully assessed to avoid (1) increasing associated environmental and health risks and (2) reducing the anticipated lifespan of the project.
