   MEMORANDUM

Arizona state prisoner Angelo Paul Per-ondi appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging deliberate indifference to his health as a result of exposure to lead contamination in the prison water. We have jurisdiction pursuant to 28 U.S.C. § 1291. We review de novo. Toguchi v. Chung, 391 F.3d 1051, 1056 (9th Cir.2004). We affirm.

The district court properly determined that Perondi failed to establish a triable issue as to whether the defendants knew of and disregarded an excessive risk to him from exposure to lead in the prison’s drinking and cooking water. See Farmer v. Brennan, 511 U.S. 825, 837, 114 S.Ct. 1970, 128 L.Ed.2d 811 (1994) (“[A] prison official cannot be found liable under the Eighth Amendment for denying an inmate humane conditions of confinement unless the official knows of and disregards an excessive risk to inmate health or safety[.]”).

The district court did not abuse its discretion in denying Perondi’s request for appointment of counsel because he did not demonstrate extraordinary circumstances. See Agyeman v. Com. Corp. of Am., 390 F.3d 1101, 1103 (9th Cir.2004). The district court also did not abuse its discretion in denying Perondi’s motion for class certification because Perondi was not an adequate class representative. See Fed. R. Civ. P. 23(a)(4) (requiring that class representative be able to “fairly and adequately protect the interests of the class”); C.E. Pope Equity Trust v. United States, 818 F.2d 696, 697 (9th Cir.1987) (lay person lacks authority to appear as an attorney for others).

The district court did not abuse its discretion in denying Perondi’s motion for a medical examination in light of Perondi’s inability to pay the associated costs. See Fed. R. Civ. P. 35 (providing no cost-shifting mechanisms); Childress v. Darby Lumber, Inc., 357 F.3d 1000, 1009 (9th Cir.2004) (reviewing for abuse of discretion decisions on discovery issues).

Finally, the district court did not abuse its discretion in denying Perondi’s request to amend his complaint to add a defendant, made after the discovery period had ended and defendants had filed their motion for summary judgment. See Flowers v. First Hawaiian Bank, 295 F.3d 966, 976 (9th Cir.2002) (denial of leave to amend after a responsive pleading has been filed is reviewed for abuse of discretion).

Perondi’s remaining contentions are unpersuasive.

AFFIRMED.
