<P>Lagoon ecosystems have been severely degraded by anthropogenic activities, which result in ecological and hydrological changes in the system. Detailed understanding of the recovery processes of restored lagoon systems has been impeded by the underlying complexity of integral environmental components. The aim of this study was to understand relationships between water quality variables in a restored lagoon, and temporal and spatial changes at each recovery stage after lagoon restoration. Ten water quality parameters were monitored on a monthly basis at 30 sampling sites in the Chilika Lagoon from 1999 to 2009. Self-Organizing Map and principal component analyses showed that salinity was the dominant factor for the Chilika Lagoon and had maximal component loading in the principal component analysis. Mean salinity level increased after opening of a new mouth in the study site, however, a decreasing trend was observed 4 years after the restoration. The pH and pCO(2) exhibited pulse-type resilience after the restoration event. The average nitrate:phosphate ratio increased steadily during the monitoring period. Multivariate analysis of monitoring data of the restoration site provided a deep understanding of its temporal and spatial change. It would be worthwhile to extend multivariate analysis to diverse ecosystems, while considering biological components is recommended in order to evaluate the comprehensive response of the restored system.

Certain physicochemical and biological characteristics of well waters located near major solid waste disposal sites of Bhubaneswar city were studied in the dry and wet seasons of 2001 and 2002. Higher levels of NO₃^(-), PO₄^(--), Cl^(-), SO₄^(---), Fe, Ca, Mg, total hardness, and total and fecal coliform bacteria have been observed in the water samples in wet seasons relative to dry seasons. Most of the physicochemical and biological parameters exceeded the Indian drinking water standards prescribed by IS:10500:1991. The results indicated that in wet seasons, the well waters within 50 meters from municipal waste dumping sites were not suitable for drinking.
