This reaction and the reaction of the sulfuric acid with silicate minerals to release Al and other elements from the mineral structures are likely pathways for the release of iron, aluminum, and sulfuric acid from SBDM into the Pocomoke Sound.
During periods of drought, SBDM may act as reservoirs of acidity where additional sulfuric acid and acid-forming salts may form; however, in cases of above-normal rainfall, large quantities of low pH effluent carrying Fe, Al and other elements can be released from SBDM.
During periods of drought, oxidising conditions are presumed to prevail thereby favouring sulfide oxidation of the SBDM.
Some suggested ways to reduce the discharge of acid and Fe- and Al-bearing waters into the Sound from SBDM deposition sites are: (i) the use of more secure dikes, (ii) the use of sealants, such as bentonite, to line the deposition cells before SBDM placement, (iii) the addition of a sufficient quantity of liming materials to the SBDM during their deposition to neutralise the acidity produced as they undergo oxidation, and (iv) keeping the DM anaerobic to retard the oxidation of sulfides.
The types of decisions being made by the SBDM Councils during the period of July 1, 1996 through November 30, 1997.
A stratified random sampling technique was chosen because an in-depth analysis of SBDM Council materials was planned and a small sample, representative of the population by both region and school level, was required to make the research study both feasible within the time constraints and generalizable to the population.
Table 1 presents the categories of decisions, with examples of decisions fitting within the category, used for coding the minutes of each SBDM Council meeting.
A random sample of 10% of the SBDM Council minutes (N=14 Councils) was also coded by a second researcher.
The earliest SBDM Councils did not reflect even this small amount of diversity.
To improve this situation, the Kentucky Legislature, during its 1994 session, mandated that any school with an 8 percent or greater minority enrollment elect a minority member to its SBDM Council, if one had not been elected in a regular election.
The Kentucky Department of Education has issued no less than four Kentucky Administrative Regulations (KARs) and six Program Reviews (advisory opinions on SBDM operations).
Most SBDM Councils have spent the first year or more of operation developing their bylaws, rather than on the more important business of Making school decision's.
