    The study aimed to establish presence of radioactivity and concentration of heavy metals specifically lead and chromium in drinking water from wells within one-kilometer radius from the approximated center of the Calahunan dump site. Results showed that four out of twelve wells have positive results fro gross alpha activity and gross beta activity: wells 2A, 2C, 3A, and 3D. Well 2A, 2C and 3D registered alpha activities of 0.54, 0.033 and 0.369 Bq/L respectively while Well 3A registered beta activity of 1.0 Bq/L. Wells 2A and 3D exceeded the radiological limits set by WHO and PNSDW of 0.1 Bq/L for alpha activity and 1.0 Bq/L for beta activity. These wells that are found adjacent to the perimeter fence of the dump site registered alpha activity (wells 2A, 2C and 3D) and beta activity (well 3A). Radiological activities in all other wells sampled registered less than lower limit of detection. For gamma activity, all wells recorded 137- Cs and 134-Cs activity less than the lower limit of detection. For chromium and lead concentration using FAAS, only well 3C has a chromium concentration of 0.0952 ppm and this exceeded the PNSDW standard for chromium in drinking water (0.05 ppm) FAAS has not recorded any value for lead. For chemical constituent analysis using XRF, two wells in zone 1 (LA and IC), have recorded lead concentration of 0.9 and 0.136 ppm, respectively. In zone two, only well 2D registered a lead concentration of 0.248 ppm. In zone 3, well 3C registered a lead concentration of 0.397 ppm. For chromium concentration, only well 2A in zone 2 has a chromium concentration of 1.79 ppm. The spot interview and ocular inspection found out that the following garbage are disposed of indiscriminately tn the dump site: (1) Television picture tubes, (2) Dysfunctional Computer Monitors, (3) Used syringes and needles, (4) Hospital wastes, (5) Automobile batteries and dry cells, (6) scrap iron, tin cans, paint cans, paint cans, etc., (7) polyethylene bottle, glass bottles, and containers of similar types, and (8) other organic and inorganic wastes. Wells whose values for gross alpha, lead, and chromium concentration exceeded the standard are unsuitable for dinking and other domestic uses. The observation that wells (2A and 3D) near the Calahunan dump site registered higher-than-standard alpha activity may be a good basis to conduct further research particularly on the effect of leachate from dump site.

    Improper home food handling preparation and consumption practices by consumers, inadequate hygiene practices, consumption of raw and unsafe food, as well as cross contamination by raw food are some factors and practices that have been implicated in food borne outbreaks in the home (Taulo et al., 2006). A survey was conducted to 27 households with children aged 0-6 years old from Barangay Lanag Sur, Tubungan, Iloilo. Of the 27 respondents, majority belong to the 30- 39(46.15%) age group, are housewives(65.38%) who were also in charge of preparing the food(53.8%), with monthly income ranging from 0-4999 pesos(57.69%). Among the respondents, six of them were randomly taken for sources of food sample which was tested for physical and microbial examination. Based on the survey, food preparation practices of households in the barangay is composed of washing, cutting, rewashing, boiling to cook/sterilize (for infant formulas), and cooling to room temperature. Majority of the respondents consume right kind of foods essential for nutritional use and use untreated spring water for its preparation. Food samples taken have pH values ranging from 6.15 to 6.975. The test for coliform indicated that two out of six households were positive for presence of coliform. Among the common illnesses of children recorded, 96% have had a history of acute respiratory infections and 84% have had episodes of gastrointestinal illness. Food handling practice in the community is simple and not capable of eliminating pathogenic substances like coliform bacteria totally.
