ONE SIGNIFICANT CHALLENGE CAUSED BY THE BREAKUP OF THE SOVIET UNION HAS BEEN THE FRAGMENTATION OF THE SOVIET STRATETIC NUCLEAR ARSENAL. THE SO-CALLED UKRAINIAN DILEMMA IS FUNDAMETNALLY A SECURITY PROBLEM FOR THE NEWLY-INDEPENDENT UKRAINE'S STATE. IT IS A QUESTION OF HOW TO BEST GUARANTEE UKRAINE'S NATIONAL SECURITY AGAINST A HISTORICALLY REALIZED AND CONTEMPORARILY PERCEIVED RUSSIAN THREAT, PREFERABLE WITH NUCLEAR WEAPONS; AND SIMULTANEOUSLY FOSTER AND MAINTAIN GOOD RELATIONS WITH THE WEST, WHICH FEELS THREATENED AND ALIENATED BY THE PROSPECT OF UKRAINE AS A NUCLEAR WEAPONS STATE. THIS ARTICLE ARGUES THAT IT IS A DILEMMA FOR THE INTERNATIONAL COMMUNITY AS WELL, AND EXPLORES ITS POLICY CHOICES WHICH HAVE REPERCUSSIONS IN UKRAINE, AND THUS, RAMIFICATIONS FOR INTERNATIONAL SECURITY.

AbstractSource control is regarded as a key principle in supporting concepts of sustainable management and integrated pollution control for diffuse non‐point stormwater runoff, with infiltration procedures being a prime component of such source‐control systems. The potential conflicts between the benefits of groundwater recharge and the risks to long‐term groundwater quality uncertainties associated with infiltration disposal are considered. The long‐term performance of a number of infiltration systems is reported in terms of their pollutant removal efficiencies, and the utility of an infiltration acceptability matrix approach is reviewed.
