S u s t a i n a b l e D e v e l o p m e n t A s p e c t s Pollution and Waste Management 031 Water quality Description This indicator measures the level to which coastal waters and river waters that discharge into the coastal area are within the water quality standards prescribed for the specific water use (e.g., drinking, swimming, boating, fishing, aquaculture, etc.). Rationale Criteria and standards for water quality are based on scientific information related to water use and potential risks to human health (e.g., transmit waterborne diseases), productivity (e.g., decrease fisheries productivity) and/or the ecosystem health (e.g., destruction and degradation of habitats). Different parameters provide indications of ecosystem health and potential threats to water use. Data Requirements Priority parameters (temporal/spatial) • Water transparency (secchi depth/total suspended solids) (marine/river/beach) • Dissolved oxygen (DO) concentrations (marine/river/ beach) • Total/fecal coliform counts (marine/river/beach) Secondary parameters (temporal/spatial) • Chlorophyll concentrations (marine/river/beach) • Nutrient (nitrates, phosphates) concentrations (marine/ river/beach) • Biochemical oxygen demand (BOD) concentrations (marine/river/beach) • Groundwater quality (nitrates and heavy metals) Results PG-ENRO’s water quality monitoring program covers Batangas Bay (8 stations) and Pansipit River (8 stations). Additional stations are tested when and where requests can be accommodated. In mid-2007, PG-ENRO initiated the monitoring of coastal waters in Balayan Bay. Results of the monitoring program indicate that total coliform and dissolved oxygen (DO) in Batangas Bay were within acceptable standards, with the exception of a sampling in June 2007 that happened to coincide with heavy rains (Figures 20 and 21). In April 2007, three out of eight Pansipit stations, namely, Pob. Lemery (3.81 mg/L); Bgy. Wawa (4.66 mg/L); and Delta Wawa (4.85 mg/L) had DO levels below standard (5 mg/L). Pansipit nutrient concentrations measured in 2002 and 2003 showed an improving trend which may be due to the dismantling of fish cages in the River, which started in 2002 as part of the Pansipit River Rehabilitation Program (Table 8). Total coliform levels in some parts of Pansipit River, Benangbang River in Balayan, and in Calumpang River were well above standard on occasion, indicating the discharge of untreated domestic sewage and animal wastes to the rivers as the likely source of contamination (Table 9). No data were gathered on groundwater quality. 98 State of the Coasts of Batangas Province
