    Using an average wastewater flow rate per resident of just over 100 gallons per day, we have derived from Underground Injection Control Program water quality reports, municipal flow, and census data calculations of the yearly loading of dissolved nutrients per resident of each Ma'alaea condo facility. Each resident generates and injects an estimated 37K gallons/per year and a range of 4 to 16 pounds of combined Total Nitrogen and Phosphorus. Detailed UIC water quality reports here.

    Fecal coliform injected cell counts, by volume and total injected, are shown in this table. Values range from <2 Most Probable Number of colony forming (or infection forming) units of bacteria per 100mL wastewater, up to 16,000 MPN/100mL, with total yearly cells per resident ranging from less than 2.8M cells, up to 22 Billion cells.
