IMPACTS OF DRILLING FLUIDSON CORAL REEFSThe skeletal extension and corallite shape ofindividuals id of the Caribbean and Atlantic ti reefbuildingcoral Montastrea annularis (Ellis andSolander) were measured after more than sixweeks' continuous flow-through exposure inlaboratory aquaria to treatments t t of 0, 1, 10 and100-ppm (l 1 -1 ) drilling mud. Linear increase ofthe skeleton (extension rate) and fossa lengthwere significantly depressed in the 100-ppmtreatment. t t Chronic exposure to 100-ppm drillingmud impairs coral skeletal growth rate andpossibly interferes with sediment rejectioncapability by lowering calical relief.Dodge, R.E., 1992. Marine Biology, 71(2), 141-147.
EPA reports potentialadverse impacts of drillingfluids and muds on coralreefs. But, presence ofdrilling muds must bepresent in concentrationstigreater than 100 ppm forfour weeks or longer todamage coral reefs.There is potential forenvironmental damage tocoral reefs <strong>from</strong> leakage ofdrilling fluids and muds, butwaves and currents wouldtend to diminish possibleimpacts along the FRT.
