Water quality monitoring in the San Bernard watershed consisting of ambient, wet weather and waste water treatment facility water quality monitoring.
San Bernard Watershed, Texas
2013 – 2014
EIH worked with the Houston-Galveston Area Council to collect water quality monitoring data for use in the San Bernard Watershed Protection Plan. Ambient water quality was monitored monthly at 12 sites and quarterly at 15 sites in the San Bernard watershed. In addition, on a quarterly basis, 15 sites were monitored during biased-flow, wet weather events. Finally, three sites located at the outfall of waste water treatment plants that discharge into the San Bernard watershed were monitored on a monthly basis. Parameters monitored included: flow, water temperature, dissolved oxygen, pH, and specific conductivity. In addition, lab tests were run on the water, that included total suspended solids (TSS), turbidity, sulfate, chloride, total hardness, nitrate + nitrite, ammonia nitrogen, orthophosphorus, total phosphorus, chlorophyll-a, E. coli, and Enterococcus.
