Contemporary data from the United States show that rates of sexual offending and reoffending have been in steady decline for decades. Nonetheless, nonprofessionals continue to view sexual violence as a community safety issue fraught with risk and uncertainty. The past 30 years have been witness to considerable research and practice in the assessment, treatment, and risk management of persons who have sexually offended. Gains have also been made in regard to prevention and citizen education. Modern day technologies include actuarial risk assessment instruments, measures of criminogenic need and treatment progress, refinements to treatment processes, and the establishment of evidence-based models. Legislative authorities in the United States and elsewhere have also attempted to affect risk in the community with, perhaps, lesser degrees of success. This article reviews current policies and practices, with a specific focus on what happens when offenders are released to the community (e.g., how public policies intended to track offenders and/or restrict their movements can negatively affect community reintegration). Comprehensive approaches to community sexual offender management are examined in addition to suggestions of unique approaches intended to ensure citizen buy-in and engagement.

Water tables in aquifer regions of the southwest United States are dropping off at a rate which is greater than can be replaced by natural means. It is estimated that by 1985 wells will run dry in this region unless adequate artificial recharging can be accomplished. Recharging with surface water is limited by the plugging of permeable rock formations underground by clay particles and organic debris.A controlled study was initiated in which sand grains were used as the rock formation and water with known clay concentrations as the recharge media. The plugging mechanism was investigated by direct observation in the SEM of frozen hydrated sand samples from selected depths.
