Total Suspended Solids mg/l A thru H Weekly TRPH mg/l A thru H Weekly

* See paragraph "a" for details on frequency of sampling.

1) Perform water column monitoring (dissolved oxygen, light transmittance, turbidity, pH, temperature, and salinity) throughout the water column at three foot intervals starting 3 feet below the surface to a point 3 feet above the bottom.

2) Collect water samples weekly to analyze for Total Suspended Solids (TSS), and Total Recoverable Petroleum Hydrocarbons (TRPH). Collect water samples at all 8 sampling locations A thru H. Collect water samples at mid-depth, at a depth matching one of the water column monitoring depths described in 1) above. Identify depth at which the water sample was taken. Samples must be analyzed by a laboratory certified under the State Water Resources Control Board's Environmental Laboratory Accreditation Program or a laboratory approved by the San Diego Regional Water Quality Control Board.

SECTION 01 57 19 Page 11 Amendment 1
