ANALYSIS OF CLANCY DRINKING WATER CONTAMINATION FROM ON–SITE SEPTIC SYSTEM EFFLUENT
No full textClancy, a small unincorporated town in Montana, is situated 11 miles southwest of Helena at the confluence of Clancy and Prickly Pear Creeks. Currently Clancy residences have only on-site drinking water wells and septic systems. Drinking water testing in 2012 and 2017 found nitrate levels exceeded the Environmental Protection Agency’s (EPA) maximum contaminant level (MCL) of 10 mg/L in some of the residential drinking water wells. Elevated nitrate levels can cause a significant health concern for infants due to methemoglobinemia (Blue Baby Syndrome).
Due to the continued detection of elevated nitrate levels in Clancy’s on–site drinking water wells further research into the drinking water quality by the Jefferson County Health Department and Montana Tech Environmental Engineering Department was conducted from February to December 2017. Six water sampling events were conducted on thirty drinking water wells spread over the community of Clancy.
The investigative study objectives were to: 1) Determine if drinking water contaminants are associated with on-site-septic systems, 2) Determine Clancy’s groundwater flow, 3) Determine if nutrient rich groundwater is contaminating Clancy and Prickly Pear Creeks, and 4) Assess the effectiveness of septic effluent identifiers. Drinking water wells were sampled and analyzed for nitrate, chloride, specific conductivity, ammonia, pH, total coliform, Escherichia coli, and radon-222, uranium, and δ 15N/ δ8O isotopes.
Results from the study found nitrate levels to exceed the Environmental Protection Agency’s MCL of 10 mg/L in 18 % of drinking wells. Uranium levels were found to exceed the EPA’s MCL of 30 µg/L in 37% of Clancy’s drinking water wells analyzed in the study. With the information provided from the water quality study the Clancy Water and Sewer District is pursuing the development of a centralized water system for the community.
Many smaller rural communities with on-site septic systems and drinking water wells, over time could likely encounter contamination of drinking water by septic effluent. Methods used in analysis of Clancy’s drinking water quality may be applied to economically identifying septic effluent contamination affecting drinking water wells in other rural communities
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
No full textIn this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
