WET WEATHER TEST PERIOD

The Humboldt County Department of Health and Human Services, Environmental Health Division, announces that the wet weather testing period for evaluation of individual onsite sewage disposal systems is open. The effective date of the opening is January 3, 2006. Under normal rainfall conditions the test period will continue until April 1, 2006. However, the testing period is subject to closure if adequate rainfall is not received for a significant period.

While not required in all geographic locations of the county, wet weather testing is required for proposed sewage disposal sites where impermeable soils necessitate percolation testing, and/or where the depth to groundwater needs to be determined. Wet weather testing is mandatory in the Waiver Prohibition Areas of Old Arcata Road, Jacoby Creek, and Freshwater and is necessary in almost every case in Fieldbrook, Hydesville, and the Trinidad Area.

All parties anticipating to subdivide land or develop sites with individual sewage disposal systems should contact a registered civil engineer, geologist, or other qualified consultant to arrange for testing as early in the wet season as possible. For some sites, the testing process may require several weeks of monitoring, so an early start will ensure completion of testing before the testing period closes.

You can obtain additional information regarding wet weather testing procedures by calling the Environmental Health Division at 445-6215 or 1-800-963-9241.
