  • 1. Statistical Valuation of the Classification Water Quality Model in San José Lagoon – San Juan, Puerto Rico Marianne Cartagena Georges Laguerre David Torres
  • 2. San José Lagoon, San Juan Puerto Rico http://www.recursosaguapuertorico.com/LagunasSJ-P3.html
  • 3. Background • San José lagoon has 4.52 km (2.81 miles) of longitude, 2.2 km of width. • Born in San Juan Bay and connects with Martin Peña Chanel, and the Torrecillas Lagoon by the Suárez Chanel • The northwest section of the lagoon is referred to as the Laguna Los Corozos.
  • 4. Background • The decades of 1950 to 1960, – Dredged to depths of up to 11 meters, – Impacting the recirculation of water that means the SJL began to change its morphology; – About 90 percent of the watershed area of the lagoon is urbanized (USGS, 1983).
  • 5. Justification and data description • According to the SJEB Program the results of water monitoring shows that its waters has contaminated – lack of oxygenation, – coliforms fecal, fecal enterococcus, – high turbidity by Secchi Depth • Degradation of ecosystems destruction of organisms. • Water Quality Grade = C. in particular habitat
  • 6. Objectives • Describe the chemical parameters of quality water existing data in the SJL. • Evaluate the relation between the chemical parameters of water such as Dissolve Oxygen, Turbidity, and Coliforms Fecal and qualification index of SJL.
  • 7. Hypothesis • H0: The Water Index to SJL does not change respect to the year. • H0: The Turbidity Variation of SJL is the same for each year of the study period of time. • H0: The month proportion of Dissolve Oxygen in SJL is random. • H0: The amount of Coliform – Fecal does not affect the Classification Water Index in SJL.
  • 8. Methodology • Prior information will be provided by SJEB Program. – Standards: The San José Lagoon components of the estuary are classified as SB waters – coastal and estuary waters intended for use in primary and secondary contact recreation, and for propagation and preservation of desirable species
  • 9. Methodology • Each one of the hypothesis can be resolve using a statistical framework and the data collected by the SJEB Program. • In accordance with the Water Quality Classification Model of in the estuary of the Bay of San Juan to establish inconsistencies in definitions and descriptions of the parameters.
  • 10. San Juan Estuary Bay Program Model • Scope = the numbers of contaminant that exceeded the PR Water Quality Standard. • Frequency = the proportion of samples for each contaminants that exceeded PR Water Quality Standards. • Amplitude = the amount by which the samples exceeded the PR Water Quality Standard. • Index: 100 – (square root (scope2 + frequency 2 + amplitude 2)/1.732
