This study was conducted to preliminarily determine present drinking water quality of selected District II communities in Cagayan de Oro, Philippines. Five community stations (total twenty stations) were established covering three months tap water monitoring. All samples were analyzed using portable meters determining the pH, dissolved oxygen (DO), temperature, conductivity, salinity, turbidity, and total dissolved solids (TDS) Overall, all studied tap water samples from selected stations passed the drinking water regulations except for conductivity (Risk quotient>1). Similarly, both pH and turbidity analyses showed a sampling date specific variations (p<0.05) while the analyses of temperature and salinity showed station specific variations (p<0.05). A strong correlation of studied parameters was also found between conductivity-salinity (r = 0.98); conductivity-TDS (r = 0.90); and salinity-TDS (r = 0.92). Extrapolating from this it can be concluded that the tap water samples were safe to drink. The study was preliminary and further analyses incorporating metals, pathogens, and organics may be needed.

Public Infrastructure vs. Residential Property Rental Value in Lagos, Nigeria PDF
Doyinsola Adeola Jimoh, Victor Olutope Ige
Basic infrastructures have suffered major neglect over a long period of time in many Nigerian cities. Yet, the efficiency of any form of human activity largely depends on the provision of efficient infrastructure which in turn affect the demand and choice of residential property. This study examined the impact of infrastructure provision on property values in Lagos, Nigeria. Questionnaires were administered on residents across the low, medium and high residential neighbourhoods as well as registered Estate Surveyors and Valuers in Lagos State. Data was analysed by both descriptive and inferential statistical tools. The study revealed that infrastructure provision has a population magnet attracting more people to settling in a particular neighbourhood. The model summary for regression of the effect of infrastructures on property values further revealed 99.8%, 99.3% and 99.7% of the sampled variations in low, medium and high density areas respectively are attributed to the residential rental value. Fair and equal distribution of infrastructures is hence recommended to reduce discrimination on the basis of availability. Also, government should embark on site and service scheme to provide infrastructures and other amenities that will enhance property values in the less accessible areas.
